[PHP] Re: Making verification code harder to OCR?
There was a thread about something similar to this on Slashdot oh, at
least a year ago. One technique that was suggested was to draw a
random image on the screen - say, a grid of colored squares, or a set
of different shapes/images - and just direct people to 'pick the blue
square' or 'click on the large house' or something to finish the
registration.
Of course, there are limits here for the color blind or those using
text browsers/screen readers...
As an alternative, if you needed to stick with text fonts, you could
use some unusual-looking ones, like old english, or a 3-d looking
one, perhaps combined with the color technique below.

Use two different shades of one color (ie. blue and somewhat lighter
blue). You may also want to do some tricks with the form of the
characters, so instead having a nice "0" on your screen, you can use
dots to somewhat represent it. (Much like the color-blindness tests
do).

If this is the query you are actually using, it is causing a PHP syntax
error due to the nested double-quotes. Use
$query_retrievetasks = "SELECT * FROM tasks, users WHERE tasks.UID =
users.User_id AND active='yes' ORDER by tasks.ID";
Note the single-quotes around 'yes'.
I'm guessing your installation is set up to not echo PHP errormessages back
to the screen, that's why you didn't see an error message.

Re: [PHP] Number Sign in String Variables
You need to urlencode() selectively; in this case, only the short_desc needs to be encoded, so you would have a statement something like echo "add_to_cart.php?item_num=$item_num&quantity=$quantity". "&sale_price=$sale_price&unit=$unit&short_desc=". url_encode($short_desc)."&wholesaler=$wholesaler&cost=$cost" ; You need to encode any parameter (everything to the right of that first '?') that might include the '?', '&'. '#' or space characters, since those all mean something special in a URL. To be safe, it's best to encode everything - or at least all strings. However, you have to encode them individually, since you need the UNencoded '&' between them to delimit parameters, and you need that '?' there to indicate the start of the parameters. I don't know the details of your program design, but there may be no reason to pass all the item details (description, sale price, etc.) in the URL anyway. Can't you just look them up in the add_to_card.php page, based on the item_num? Thus, all you need to pass are the quantity & item_number: echo "add_to_cart.php?item_num=$item_num&quantity=$quantity"; For one thing, that would eliminated the possibility of someone trying to get everything for free by manually typing a URL like add_to_cart.php?item_num=SOU3432410&quantity=1&sale_price=0&unit=... -steve At 6:29 PM -0500 1/18/03, Joab Stieglitz wrote: OK.

Re: [PHP] Word Count
To be somewhat more rigorous, you could do:
$numOfWords = count(preg_split('/\s+/', trim($string)));
(also untested); this ignores leading/trailing whitespace, and deals
with multiple spaces/tabs between words. There is an example in the
docs (below) called 'Get the parts of a search string' that shows how
to add other characters that you might consider valid word delimiters
- eg, a comma.
See
http://php.he.net/manual/en/function.preg-split.php

Umm, no. then you'll have $City = "North", $State = "Little" and $Zip =
"Rock" with the last example.
The following works:
$str = "NORTH LITTLE ROCK AR 72118-5227
JUNEAU AK 99801
ANCHORAGE AK 99507-6420
NORTH CARO MI 48732
";
preg_match_all('/^(.*)([a-z]{2})\s+([0-9]{5}(-[0-9]{4})?)/im',$str,$matches)
;
$count = count($matches[1]);
echo $count . ' addresses found:';
for($x=0;$x<$count;$x++)
{
$city = trim($matches[1][$x]);
$state = trim($matches[2][$x]);
$zip = trim($matches[3][$x]);
echo "City: $city, State: $state, ZIP: $zip";
}

Re: [PHP] chill out
Well, you could do what the sunmanagers mailing list does...every so often (every month? every other month?) a 95KB FAQ is sent to all subscribers. However, the main problem is getting people to READ it. And those people likely to read it are probably the same people who'd do the requisite documentation/web search first anyway. I suppose you could set it up so that only new subscribers got the FAQ. Or if you want to be really ambitious/annoying, new subscribers would get the FAQ, then - to activate them on the mailing list - they'd have to take a short web-based quiz on the contents of the FAQ before they are allowed to post. However, as others have said, the signal-to-noise ratio of this list is pretty high, easiest thing is just to tolerate/ignore the inappropriate questions... -steve At 2:21 PM +0500 4/4/03, Haseeb Iqbal wrote: hi all, just like to add something here, (which i recmended before) there should be a automated way to email all the new users about what php is, that explain them that php is server side and it can't do client side, just a plain email will do this will certinaly minimize the no of off topic posts,what you people think? i think it will help Friendship is always a sweet responsibility, never an opportunity.

I assume you mean
if () :
else if ():
else :
here (colon instead of semicolon)? AFAIK PHP doesn't allow the
alternative syntax -
http://php.he.net/manual/en/control-structures.alternative-syntax.php
- with semicolons. Or do you really mean
if () {}
else if () {}
else {}
If you are using the alternative syntax, I recall several messages
about people having problems nesting both forms of syntax. Try using
all one style or the other.
Lastly, quadruple check that you haven't accidentally quoted or
double-quoted a { or ( or something that you THOUGHT was part of PHP
code; syntax highlighting editors can definitely help here.

Not 100% sure if I understand the drift of your question, but here's a few
possibilities.
(1) Are you concerned about whitespace you put in a PHP program to enhance
readability slowing down page loads?
Any whitespace WITHIN PHP tags does not get sent to the browser at all. So
you don't need to worry about it.
(2) Are you concerned that the OUTPUT of your PHP program and/or HTML
embedded therein might have excessive whitespace? If so, you could create
an output handler that cleans up the output before sending, I think; see
http://www.php.net/manual/en/ref.outcontrol.php
Or, use compression. See:
http://www.php.net/manual/en/function.ob-gzhandler.php
(3) If you simply wanted to clean up excessive whitespace in a file, you
could use a snippet like:
...read file into $file variable
# Replace multiple spaces/tabs with a space
$file = preg_replace('/[ \t]{2,}/','/ /', $file);
# Replace multiple lines with single line
$file = preg_replace('/(\n|\r|\r\n){2,}/', '\r', $file);
...write $file back out
That last line for replacing multiple blank lines is probably wrong; at the
very least you'd have to do some platform checking (Win vs. Mac vs. Unix)
to get the proper line ending. You might also be able to use the pattern
'/(^$){2,}/m'
In PHP4 I think you can use arrays:
...read in
$file = preg_replace(
array('/[ \t]{2,}/', '/(\n|\r|\r\n){2,}/'),
array('/ /', '\r'),
$file
);
...write out
See
http://www.php.net/manual/en/function.preg-replace.php

Re: [PHP] PHP and Apache
It's certainly _possible_ -
Your httpd.conf (I'm assuming you use Apache, of course) file is just
a text file that can be read/written like anything else. Then you
could do a
system('/path/to/apache/bin/apachectl restart');
to activate. Doing it this simply, thoughm means that your
webserver's user (usually nobody) would have write access to the conf
file and execute perms to apachectl, which could open up some
bulldozer-security holes. At the very least, you want to access
things through SSL.
But you might want to try Webmin:
http://www.webmin.com/
Looks very comprehensive, and I've seem a number of good
recommendations for it. I've been planning on doing a little testing
of it on my test server, but haven't had the time.

Re: [PHP] Need more memory... possible to set?
Several ways:
(1) PHP still reads a php.ini file, so you could set it there; try a
php -i | grep php.ini
to find out where the commandline php thinks it is (and/or do
php -i | grep memory_limit
to find the default memory limit setting.
(2) You can set it at execution time via the -d command option:

Re: [PHP] Regular Expression
As someone else mentioned, filenames with embedded spaces can be
confusing and should be avoided where possible (in the future, I'd
replace the space with an underscore _). However, the following will
do what you want (untested):
$regs = preg_split('/\w+/', $dirline, 9);
$regs[8] will contain the filename, even if it has spaces.
Explanation: the regex splits the line on strings of whitespace
(spaces, tabs, etc.), for a maximum of 9 elements. Since $regs[8],
containing the filename, is the ninth element, the rest of the line
is dumped into that element without further regex processing.
Since the spacing pattern remains the same from a unix ls -l command
no matter what the file size or date is, you should be ok. See
http://php.he.net/manual/en/function.preg-split.php
for more info.
Also, if you are doing something like
$output = `ls -l`;
and then parsing the output you may want to investigate PHP's
file/directory functions instead:
http://php.he.net/manual/en/ref.dir.php
http://php.he.net/manual/en/ref.filesystem.php

The above regular expression works fine in every except when the filename is

Notice in this case the filename is "6 fantasy" however $regs[1] returns

Can anyone help me to fix this problem.

Actually, using your original query and referring to

Subject: [PHP] PHP and MySQL sorting using COUNT
I'm sorting records using COUNT with the following mysql command
$result = mysql_query ("SELECT company_name, agent_name, count(*) FROM
$cur_listings GROUP BY company_name, agent_name");
Running this in MySQL does exactly what I need it to do but how do I echo
the COUNT portion of the array? I know the company_name would be
$row['company_name'] and agent_name is $row['agent_name'];
Thanks,

[PHP] mysql/php large integer query oddity
I have a query oddity that looks like an integer overflow, but it shouldn't be.
Excerpt from my program:
#DEBUG
echo "\n$Query\n";
#DEBUG
$hResult = _do_query(__LINE__, $Query); # _do_query() simply
executes mysql_query, and does nice error formatting if necessary
$First = true;
while ($Row = @mysql_fetch_array($hResult)) {
if ($First) {
$First = false;
show_table_open($Myself);
}
echo
'',
'', $Row['source_code'], '',
'', $Row['chromo_code'], '',
'', $Row['type'], '',
'', number_format($Row['min_exon_length']), '',
'', number_format($Row['max_exon_length']), '',
# '', $Row['min_exon_length'], '',
# '', $Row['max_exon_length'], '',
"\n";
}
This produces the output
select sm.source_code,chromo_code,type,min(end_coord-start_coord+1)
as min_exon_length,max(end_coord-start_coord+1) as max_exon_length
from source_master sm left join chromosome_master chm using
(source_code) left join contig_master cm on
(cm.chromosome_id=chm._id) left join contig_position cp on
(cp.contig_id=cm._id) group by chromosome_id,type order by
sm.source_code,chromo_code,type

HOWEVER, if I cut & paste the echoed query to the mysql commandline, I get:

+-+-++-+-+
75 rows in set (9.15 sec)
Notice that I get bizarre results on min_exon_length for the
'unspecified type' lines; in addition, the max_exon_length is off 3
of the 5 times. All of the other 75 rows are identical. Is there some
setting in my.cnf or php.ini that I need to check - perhaps
mysql_always_return_correct_results? I tried echoing the results out
directly instead of using number_format(), but there was no change in
the numbers. I've never seen anything like this...perhaps I need more
coffee?

I think your problem lies in a misunderstanding of the
mysql_fetch_array() function. It doesn't return the entire result set
in an array - just one record at a time. You can fix this in one of
two ways:
(1) Loop though the entire result set in your function:
function getCourses($UID)
{
global $link;
$ResultSet = array();
$result = mysql_query( "SELECT C.CourseName FROM tblcourses C, tblusers U,
tblEnrollment E WHERE C.ID = E.CourseID AND E.UserID = U.ID AND U.ID =
$UID", $link );
if ( ! $result )
die ( "getRow fatal error: ".mysql_error() );
while ($Row = mysql_fetch_array( $result ))
{
$ResultSet[] = $Row['C.CourseName'];
}
return $ResultSet;
}
...
$myCourses = getCourses($session[id]);
foreach ($myCourses as $value)
{
print "$value";
}
or (2) set a flag in getCourses() so that the query is only executed
once, otherwise returning a result line - something like:
function getCourses($UID)
global $link;
static $result = false;
if (!$result)
{
$result = mysql_query( "SELECT C.CourseName FROM tblcourses C,
tblusers U,
tblEnrollment E WHERE C.ID = E.CourseID AND E.UserID = U.ID AND U.ID =
$UID", $link );
if ( ! $result )
die ( "getRow fatal error: ".mysql_error() );
}
{
return mysql_fetch_array( $result );
}
...
while ($Row = getCourses($session[id]) as $value)
{
print "", $Row['C.CourseName'];
}
(standard caveats about off-top-of-head, untested code apply)
The reason you are getting the first record TWICE is becaouse of the
default behaviour of the mysql_fetch_array() function. It returns
both an associative array - ie, elements of the form =>
- and a numerically indexed array (0, 1, 2, etc.). You can
alter this behaviour by the second parameter of the function: see
http://www.php.net/manual/en/function.mysql-fetch-array.php

Just to clarify a bit - mysql_fetch_array() DOES return an array -
thus the name - but it is an array containing one record from the
result set. For instance, if the result of the statement
SELECT C.CourseName
FROM tblcourses C, tblusers U, tblEnrollment E
WHERE C.ID = E.CourseID AND E.UserID = U.ID AND U.ID = 1
through the MySQL commandline was
+-+
| C.CourseName|
+-+
| Basketweaving |
| Noodle twirling |
| Poodle furling |
| Puddle curling |
+-+
then the first use of mysql_fetch_array($result) through PHP would
retrieve the array
'C.CourseName' => 'Basketweaving',
0 => 'Basketweaving'
the second call would retrieve
'C.CourseName' => ' Noodle twirling',
0 => ' Noodle twirling'
and so on. If you had two columns in the result set:
+-++
| C.CourseName| C.CourseNo |
+-++
| Basketweaving | 12 |
| Noodle twirling | 23 |
| Poodle furling | 24 |
| Puddle curling | 25 |
+-++
you would get results like
'C.CourseName' => 'Basketweaving',
0 => 'Basketweaving',
'C.CourseNo' => 12,
1 => 12
and so on. The reason you get the doubled keys (associative &
numeric) is for historical compatibility; to turn off the feature,
and retrieve only the associated indexes (the behavior you normally
want), you can use
mysql_fetch_array($result, MYSQL_ASSOC);
Incidentally, I just learned something here myself; there's a
relatively new (>= version 4.0.3) function mysql_fetch_assoc() which
does what you want...return ONLY the associated indexes. See:
http://www.php.net/manual/en/function.mysql-fetch-assoc.php

No, but you can do it this way:
switch ($foo) {
case 1:
...
do_something();
break;
case 2:
...
do_something();
break;
case 3:
do_something();
break;
}
function do_something() {

This accomplishes the same thing.

No, because AFAIK all PHP arrays are associative; there is no
distinction between arrays & hashes as in Perl.

If you really don't want to use mysql_fetch_assoc(), you can use the

$arr = mysql_fetch_array($ResultHandle, MYSQL_FETCH_ASSOC);
This functions exactly like mysql_fetch_assoc(), and is available in
PHP >= 3.0.7.

Re: [PHP] Random Character Generator
Well, here's an untested script off the top of my head:
function random_string($Ncharacters) {
static $CharList = '0123456789abcdefghijklmnopqrstuvwxyz';
$String = '';
$Max = strlen($CharList)-1;
for ($i=0; $<$Ncharacters; $i++) {
$String .= $CharList{rand(0, $Max)};
}
return $String;
}
For php < 4.2.0, you'll need to seed the random number generator first; see
http://www.php.net/rand
You could probably also make something up using rand in conjunction with ord():
http://www.php.net/ord
Also see:

Re: [PHP] Can you recommend a good PHP includes tutorial?
And, you can even do this automatically using the auto_prepend_file
and auto_append_file settings:
http://us3.php.net/manual/en/configuration.directives.php
These can be set in your Apache config file, php.ini or .htaccess, so
you can control what files are used down to the lowest subdirectory

Of course, if you need to include() in the middle of a page, or
conditionally include files, these won't work -

'require' ALWAYS includes the file; 'include' is what you want here.
The tradeoff is that include is slightly slower. For more info, see

The extent of this overhead depends on whether you're running PHP as a module or as a CGI. With CGI, the overhead is quite large, probably too much unless you have a really meaty server or a lightly-hit web site. For an Apache module, I recall a test someone ran > 1 year ago that resulted in an extra ~4 % load for parsing plain html pages through php (as opposed to just statically serving the html pages).

For example -
$NewString = ereg_replace("([[:alpha:]]+) ", "\\1".chr(9), $String);
This will convert a sequence of one or more alphabetic characters followed
by one space to the same set of characters followed by a tab (that's the
chr(9) part).
If you want to match only a specific set of text characters - say, a, e, i,
o and u - then you can use
$NewString = eregi_replace("([aeiou]+) ", "\\1".chr(9), $String);
Notice i used eregi_replace() instead of ereg_replace(); the 'i' means case
INsensitive.
Of course, there are other ways of doing this with preg_replace and
str_replace, both of which are faster than ereg_replace (str_replace is the
fastest); I happen to use ereg becaouse I'm most familiar with it, since it
came along before the preg_ functions. As always, you can check out the docs:
http://www.php.net/ereg_replace
http://www.php.net/eregi_replace

If you really need to make this a float variable, then you can add
$Number = (float)$SanitizedNumber;
although in most cases PHP handles type conversion correctly on-the-fly.

Did you think of

$method = 'doIt';
$this->$method('yes');
}
function doIt($Answer) {
echo "Noodles are happy? $Answer";
}
}

I assume you're talking about Netscape on Windows? If so, yes it runs fine, but only as a CGI - I used to have that setup until I moved to an Apache/PHP module configuration. Off the top of my head, I had (1) set up Windows file associations to associate .php extension with PHP.exe (2) created Shell CGI directories for all my php scripts There was a better way that someone had come up with that avoided step (1) by editing the mimetypes.conf (?) file and associating the php extension with the php executable within Netscape, but I can't remember that method offhand - it's been a while. Also, if you're looking for Netscape on Unix information, there used to be a website that explained how to compile PHP to run as a NSAPI module; unfortunately, that URL disappeared.

Just to explain the error -
split() takes a regular expression for its first argument; '+' is a
special character for regular expressions, and is not valid by
itself. That's why you're getting an error. For more info on regular
expressions, there have been links to good tutorials that pop up from
time to time on this list; also, I think there are a few references
mentioned in the online docs for the ereg_ and preg_ functions. You
can also get the O'Reilly book 'Mastering regular expressions.'
That being said, though, explode() is probably a better function to
use here. If you don't need the functionality of regexps, explode()
is faster.

Some browsers will save the entered info when you hit the BACK
button, some won't; it also depends on your HTTP header settings
(no-cache, must-revalidate, etc.). Probably bad idea to rely on that.
In a nutshell, if your validation fails, don't tell the user to hit
the back button. Instead, redisplay the form with the data fields
already filled in.
I usually write my form display & process programs something like
this (assuming $Submit is the name attribute of the submit button):
...
if ($Submit = 'Enter your data') {
$ErrorList = validate_form_data();
if (is_array($ErrorList)) {
show_form($ErrorList);
} else {
process_data();
}
} else {
show_form();
}
...
Where:
validate_form_data is a function that returns an array of
error messages like $ErrorList[] = ,
or FALSE if all tests passed. If there are errors, I redisplay the
form with entered data (from $HTTP_POST_VARS or wherever), and error
messages displayed alongside the appropriate form fields.
show_form displays the entry form, with any existing data
(from HTTP_POST_VARS, etc.) filled in and error messages, if any,
displayed. Basically, the FORM tag action attribute refers to the
same program as displayed the form - that is, $PHP_SELF.
Hope this is clear...I getting tired, and I don't even think an
intravenous drip of concentrated Mountain Dew syrup will help.

From
http://www.php.net/manual/en/function.eval.php :
"A return statement will terminate the evaluation of the string
immediatley. In PHP 4 you may use return to return a value that will
become the result of the eval() function while in PHP 3 eval() was of
type void and did never return anything."
So, if you're using PHP4, just ensure that there is a return

Of course, you would want to do your own processing in place of the echo.
If you want to use POSTed or cookie variables, replace the _GET_ in
the above snippet with _POST_ or _COOKIE_, respectively.
The reset(), by the way, resets the array pointer to the beginning of
the array. It's not always needed, but I tend to do it anyway. It IS
necessary, however, ig you use the above snippet within an enclosing
loop.

An easy way to read the returned array values into scalar variables is:
list($lang_pref, $currency_pref) = PrefChange($language,
$currency, $state);
You can only do this if your PrefChange function _always_ returns the
same number of elements (two here; it could be any number). If you
have a function that - for example - returns a 2-element array or
FALSE if there's an error, then you have to do something a little
more complex:
$Stuff = PrefChange($language, $currency, $state);
if (is_array($Stuff))
{
# ...do stuff with $Stuff !
} else {
# ...show error message
}

Take a look under date/time functions:
http://www.php.net/manual/en/ref.datetime.php
You want to convert your stored time into a Unix timestamp (that is,
seconds since midnight 1 jan 1970), subtract the unix timestamp of
the current time, and then display the result in your desired format:
$Deadline = ' 27:01:2001:08:13';
$Bits = explode(':', $Deadline);
$TimeDiff =
mktime($Bits[3],$Bits[4],$Bits[5],$Bits[1],$Bits[0],$Bits[2])
- time();
# $TimeDiff is now the time difference, expressed in seconds.
# Now, use modulo operator repeatedly to get day, hour & minute values.
# BTW, there are 86400 seconds/day, 3600 seconds/hour.
$NDays = $TimeDiff % 86400;
$R = $TimeDiff - ($NDays * 86400);
$NHours = $R % 3600;
$R = $R - ($NHours * 3600);
$NMinutes = round($R/60);
echo "You have $NDays days, $NHours hours and $NMinutes left!";
If you're feeling obfuscatory, you could compact the calculations
into (I think):
$NHours = ($R = $TimeDiff - (($NDays = $TimeDiff % 86400) *
86400)) % 3600;
$NMinutes = round(($R - ($NHours * 3600))/60);
Why you would _want_ to do this, I don't know. I suppose if you're an
ex-FORTRAN programmer frustrated by the lack of assigned and computed
GOTOs and want to take it out on others, maybe. OK, now I'm rambling.
And showing my age...

Are these actual program snippets? If they are then
(1) '$test1 = array()' line is missing a trailing ';'
(2) The statement 'list($test,$test1);', to the best of my knowledge,
does nothing in this context.
(3) From your echo statement, you should see the output
'list(Array,Array)' - functions and language constructs aren't
evaluated in double-quoted strings; only variables.
It would make more sense to me to have something like
$test = array('bean', 'noodle', 'wednesday');
$test1 = array('a'=>'apple', 'b'=>'banana', 'c'=>'carrot');
$foo = array($test, $test1);
Then you could display these values like so:
If you have PHP4, use print_r() or var_dump():
echo print_r($foo);
See
http://www.php.net/manual/en/function.print-r.php
http://www.php.net/manual/en/function.var-dump.php
I haven't used either of these functions, so I don't know exactly
what the output looks like. It says var_dump() was available in PHP 3
after 3.0.5, but I'm not entirely sure that's true. If it is, it must
have been undocumented for a while.
An alternative display method would be something like (a little more
cumbersome, but works in PHP3 & 4):
for ($i=0; $i\n";
}
}
Also, instead of the
$test = array('bean', 'noodle', 'wednesday');
$test1 = array('a'=>'apple', 'b'=>'banana', 'c'=>'carrot');
$foo = array($test, $test1);
way of declaring the $foo array, you could also say
$foo = array(
array('bean', 'noodle', 'wednesday'),
array('a'=>'apple', 'b'=>'banana', 'c'=>'carrot')
)
or
$foo[0] = array('bean', 'noodle', 'wednesday');
$foo[1] = array('a'=>'apple', 'b'=>'banana', 'c'=>'carrot');
See
http://www.php.net/manual/en/language.types.array.php
for more information.

Because that's the way it is ;).
The var is part of the syntax of a class definition; it isn't used
anywhere else. I don't know the actual deep reason for having it, as
far as the parser is concerned, but it does make it clear - at least
to me - what the class variables are.
You can also initialize the variable here, too:
var $a = 5;

Yep.
You can also _set_ $a this way:
$test = new simple;
$test->a = 77;
echo $test->first();
will display 77.

If you meant $run3 on the third time line, then you can use
for ($i=1; $i<$SomeNumber; $i++)
{
$SomeValue = some_function(${run$i});
}
Or, use could say
for ($i=1; $i<$SomeNumber; $i++)
{
$VarName = "run$i";
$SomeValue = some_function($$VarName);
}
If you actually _wanted_ to use '$run2' on the third time, I'm
interpreting that to mean you want to limit the maximum value of the
digit to 2. If so, you could do
for ($i=1; $i<$SomeNumber; $i++)
{
$VarName = 'run'.max($i, 2);
$SomeValue = some_function($$VarName);
}

Re: [PHP] isset()
I would do this:
if (!$AgeChild) $AgeChild = 'NA';
More compact, easier to read (to me, anyway). This presumes that a
value of '' (empty string, interpreted by PHP as false) is NOT a
valid value here.
As far as your sniplet goes, it is possible that there may be some
PHP type-casting issues here, depending on: whether $AgeChild is
numeric or string; the fact that the STRING "false" isn't equivalent
to the CONSTANT false, the use of == vs. ===.
Time to check out the docs - specifically the types and variables
sections (also the functions->variables section)...

I think - if you're feeling obscure - that
$count = 0;
while
(($count <= 10) && print 'Number is '.$count++." \n")
{}
will work too. As will - using alternate while syntax -
$count = 0;
while ($count <= 10):
echo 'Number is '.$count++." \n";
endwhile;

In your HTMLTable() function, use
$this->attributes[] = array("border", "0");
$this->attributes[] = array("cellpadding", "0");
otherwise, PHP thinks $attributes is a variable local to that
function, rather that a class variable.

Well, in this case, you'd have to use regular expressions. One way to do it
would be:
$SanitizedString =
ereg_replace('<[[:space:]]*([[:alnum:]]+)[^>]*>', "<\\1>", $String);
this _should_ work (haven't tested it). If you wanted to remove some tags
entirely, and then remove the attributes of the remaining tags, you could
(1) use strip_tags() with a list of allowable tags, then (2) run the regexp
above. Incidentally, the above regexp also removes leading spaces from the
tag. Eg, < font style="unreadable"> becomes . If you don't want,
that user the regexp
'<([[:space:]]*[[:alnum:]]+)[^>]*>'
instead.

Well, just offthetopofmyhead:
function word_occurrence($word,$phrase) {
$word = strtolower($word); # this way,
$phrase = strtolower($phrase); # case is irrelevant
$Bits = split($word.'[^[:alnum:]]*', $phrase);
return (count($Bits)-1);

I tested this, and it works fine (php 3.0.12) EXCEPT it counts
'coffecoffe' as TWO words, not zero. If that's the behavior you want,
then it's fine. Now I'm intrigued...I want to find a single regular
expression that will NOT match 'coffecoffe'. Perhaps preg_ functions
(available on PHP >= 3.0.9).
And, I tried things like
split('[^[:alnum:]]*'.$word.'[^[:alnum:]]*', " $phrase ")

Re: [PHP] Extract from string, version 3.0
Sheesh! No one should let me reply to email without sufficient
caffiene! Now, I actually just read and grokked your question...
I haven't tested this. And, I included a line that removes
apostrophes (eg; "steve's" becomes "steve"). You can comment that
line out if this doesn't suit your needs. The function returns an
array of all words that meet or exceed your threshold count, sorted
by decreasing frequency (you can remove the sort section too, if you
don't need it).
Sorry about the previous two messages...
function your_dream_function($phrase, $threshold) {
$phrase = strtolower(trim($phrase));
$WordList = $Temp = array();
$Bits = split('[[:space:]]+', $phrase);
for ($i=0; $i= $threshold) { $WordList[] = $Temp[$i]; }
}
return ($WordList);
}
Some notes:
(1) I can't recall if PHP3's arsort() would treat the array value as
a string or as a numeric. I think it would always treat the value as
a string (meaning that '2' would come before '12' in an descending
sort), so in that case you would have to modify the function above in
one place (only if you wanted the sort):
Replace
$Temp[$Bits[$i]]++;
in the first for loop with
$x = $Temp[$Bits[$i]]++;
$Temp[$Bits[$i]] = substr(1+$x, 1);
This should left-pad the number with zeros (for up to
occurrences found), so that the ASCII sort sequence is in numeric
order. Using PHP4's arsort($Temp, SORT_NUMERIC) would be much handier!
(2) Iff (if and ONLY if) you are using the sort, you could get a
slight speed improvement by modifying the second for loop as follows;
replace
if ($Temp[$i] >= $threshold) { $WordList[] = $Temp[$i]; }
with
if ($Temp[$i] >= $threshold) {
$WordList[] = $Temp[$i];
} else {
break; # all subsequent words will be below the threshold
}
Again, this is all untested code.

Re: [PHP] var question
You can also look at environment variable $QUERY_STRING. For example,
if ($HTTP_SERVER_VARS['QUERY_STRING'] == 'login') {
...do log in procedure
If register_globals is on, all you need is
if ($QUERY_STRING == 'login')
If you might be passing other parameters in the URL, and want to ignore
case, you could use something like:
if (eregi('login', $QUERY_STRING)) {
This would match
www.blah.com?login
www.blah.com?LogIn
www.blah.com?login&user=herman_hollerith
but it would also match
www.blah.com?sloginthemud
www.blah.com?login0
So, a little regular expression twiddling might be in order.

I think this used to be in the docs or notes, but I couldn't find it
when I did a quick search.
As I understand it, mysql_error() and mysql_errno() only return
errors on an active connection. So, if the error occurs on
mysql_connect/pconnect(), they will not return anything. So, you can
do something like:
$LinkId = @mysql_connect(...);
if (!$LinkId) {
call error_function('Unable to connect to database;);
exit;
}
or, more simply:
$LinkId = @mysql_connect(...) or die('Unable to connect to database');
There's no way that I know of to get more details on WHY the connect
failed other than not using the '@' and seeing what the mysql_connect
error message does. In PHP4, you might be able to catch that message
using the output buffering functions, then format that the way you
want. See
http://www.php.net/manual/en/ref.outcontrol.php
for more info on output buffering.

AFAIK, it will reread the .ini file every time only if you're running PHP as a CGI, as opposed to an Apache module (or ISAPI or NSAPI module, but I don't think either of those are industrial strength yet).

Re: [PHP] string to array??
Actually, you can treat a string as an array without any further processing:
$Globbot = 'dribcot';
echo $Globbot[0]; # echoes 'd'
echo $Globbot[6]; # echoes 't'
Check out 'String access by character' about halfway down the page at
http://www.php.net/manual/en/language.types.string.php
(or, in Portuguese,
http://www.php.net/manual/pt_BR/language.types.string.php
).
Actually, using the [] syntax is deprecated - using {} is the new way
- but I'm a creature of habit...

Re: [PHP] string to array??
Sorry if I was less than totally clear; I was referring to this part
of the page:
Characters within strings may be accessed by specifying the
zero-based offset of the desired character after the string in curly
braces.
Note: For backwards compatibility, you can still use the
array-braces. However, this syntax is deprecated as of PHP 4.
Example 6-3. Some string examples
/* Get the first character of a string */
$str = 'This is a test.'
$first = $str{0};
...and that was the first I'd noticed that myself; I assume that the
{} syntax is only being used to refer to arrays as strings, to avoid
confusion with an array of strings -
$str = array('string 1', 'thing 2');
echo $str[0]; # produces 'string 1'
- and a scalar string variable being treated as an array of
characters. So I'm guessing (too lazy to test right at the moment)
that you would get
$str = array(array('bork','fubar'), 'snafu');
echo $str[0][1]; # produces 'fubar'
echo $str[1][1]; # produces null
echo $str[1]{1}; # produces 'n'
Again, that's just what I'm assuming from the docs. A quick test
would clear it up, but it doesn't affect me right now, and I'm
feeling lazy ;)
Hope that clears up my statement...

[PHP] Re: Any Ideas
Or do it all in one line:
$string = ereg_replace('[!@#$%^&*()_+=-';:"/.,<>?]', '', $string);
If you want to remove non-alphanumeric characters from a string, you can do:
$string = ereg_replace('[^[:alnum:]]', '', $string);
Perl-compatible regular expressions would work as well, and be
slightly faster. For more info, see:

Re: [PHP] Book database (slightly OT)
Perhaps the Library of Congress?? http://www.loc.gov/z3950/ You could hack the web interface, but it would be more efficient to query the database directly using the Z.39.50 stateful protocol: see http://lcweb.loc.gov/z3950/gateway.html#about and http://www.niso.org/standards/resources/Z3950_Resources.html among other places. You could probably write a pretty decent interface using PHP's socket functions, but it would be more efficient to write a PHP extension for it - depending on how intense your searches were. That was on my to-do list for a project a few years ago, but I'm no longer working on that. -steve At 4:32 PM -0500 1/29/02, Reuben D Budiardja wrote: >Hi, >I am working on a projects for book cataloging.

Re: [PHP] Using a mysql data base and cookie to log a person in
Have you considered PHPLIB? http://phplib.sourceforge.net/ http://sourceforge.net/projects/phplib http://www.sanisoft.com/phplib/manual/ The docs'll give you an idea of how they did it. The code is pretty complex, though, but it does a lot. I'd suggest using this as a base, if PHP4's session handling isn't sufficient. I use it, with my own hacks for my authorization needs. -steve At 8:38 AM -0800 2/20/02, Brandon Orther wrote: >Hello, > >I loosely understand how I can have a person login to a system by giving >them a cookie with a certain amount of time with a encrypted code.

Re: [PHP] viewing get/post variables
You might be thinking of the register_globals parameter here, instead of safe_mode: http://php.he.net/manual/en/configuration.php#ini.register-globals It is, in general best to keep this off so that you can explicitly validate user input. If you trust the POST or GET data, though, you can turn register_globals ON or use the extract() function - http://php.he.net/manual/en/function.extract.php - for example: extract($HTTP_GET_VARS); echo $var1; or in a function, extract($GLOBALS['HTTP_GET_VARS']); echo $var1; I don't think the safe_mode setting affects this, but I'm not sure. Some of the default settings may have changed between 4.0.6 & 4.2; that might explain why behavior changed after upgrading. -steve At 10:43 AM -0300 4/16/02, Martín Marqués wrote: >On Mar 16 Abr 2002 10:35, Christoph Starkmann <[EMAIL PROTECTED]> wrote: >> Hi Martín! >> >> > I can't remmeber how to configure php.ini so that if I get the URL >> > http://localhost/index.php?var1=10 >> > an echo $var1 will return 10 >> > What I mean, is that _GET["var1"] exists, but I want $var1 to >> > be available. >> >> If $var1 is not available directly, your safe_mode seems to be >> turned on. >> One way would be to turn safe_mode off again: change the line >> >> safe_mode=On >> to >> safe_mode=Off > >safe_mode is Off. > >> in your php.ini. >> >> The safer way would be to prepare $var1, for example like this: >> >> $var1 = $HTTP_GET_VARS["var1"]; >> >> Now you can use $var1. > >Before I upgraded PHP form 4.0.6 to 4.2.0RC2 it worked directly, without >having to pass the $HTTP_GET_VARS. > >Saludos... :-) > >-- >Porqué usar una base de datos relacional cualquiera, >si podés usar PostgreSQL? >- >Martín Marqués |[EMAIL PROTECTED] >Programador, Administrador, DBA | Centro de Telematica >Universidad Nacional > del Litoral >- -- ++ | Steve Edberg [EMAIL PROTECTED] | | University of California, Davis (530)754-9127 | | Programming/Database/SysAdmin http://pgfsun.ucdavis.edu/ | ++ | "If only life would imitate toys." | | - Ted Raimi, March 2002 | | - http://www.whoosh.org/issue67/friends67a.html#raimi | ++ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Making varibles (more than one) with a function.
Because global is specific to the SCOPE not to the variable -
variables themselves aren't tagged as global. If you add
global $text;
in your echoo() function it will work. Alternatively, you could replace
echo $text;
with
echo $GLOBALS['text'];
in your echoo() function.
See
http://www.php.net/manual/en/language.variables.php
for more info.

I have done a similar thing by executing another script via sudo using the PHP command passthru() (or you could use exec(), system(), whatever's appropriate). See http://www.courtesan.com/sudo/ for more info. The whole setup was (and is) a bit of a kluge, but the script didn't need to be run often so it doesn't impact server performance any. -steve At 09:37 AM 3/28/02 , Ken Nagorski wrote: >Hi there, > >I have a little problem.

Re: [PHP] arguments against php / mysql?
Other people have made similar arguments, but just thought I'd throw in my 2c:
I had a couple of years experience running MySql (3.22.something) on
WinNT4sp5, 3-4 years with PHP as a CGI (going all the way back to
PHP2 aka PHP/FI) and ~9 months using Apache/PHP on Windows. As of
last fall, I have no Windows machines anymore, so my recollection at
the moment of details/versions is a bit fuzzy.

While I had fairly modest database usage, I NEVER had a single
problem with MySQL/Windows. It was fast, took up very little memory,
was about as close to set-and-forget as I've seen.

As others mentioned, this is obsolete info; I migrated sites running
on Netscape Enterprise 3.5 & IIS to Apache with the PHP module (I
believe the versions were 1.3.20 & a fairly early PHP4) with few
problems (the biggest of which were a few functions that didn't work
as expected in a PHP release candidate, but there were simple
workarounds and - well, it was a release candidate not a final
release). I used the PHP modules from PHP4WIN:
http://www.php4win.de/
By the way, the Apache/PHP-based solution worked much better than the
ColdFusion stuff I was running on the same server. Cold Fusion sucked
up tons of RAM, and on occasion database queries on an Access
database caused CPU usage to spike at 100% until I restarted the CF
server.
If you want to use PHP with IIS, then it is my (likely obsolete &
incorrect) understanding that the PHP ISAPI version is still somewhat
experimental, and that CGI is the recommended approach there. But
then, I would avoid IIS as a web server to begin with.
>3. Loss of verity - the powerful search engine bundled with Cold

I'm sure you could still use Verity, but yes - you'd have to purchase
it separately. I had just started using htDig -
http://www.htdig.org/
- as a search engine on the Windows box, but I didn't get much of a
chance to get production experience with it. There's also MnoGoSearch
-
http://www.mnogosearch.ru/
- which looks promising (and is pretty popular on the Unix side), but
I don't have any experience with it. And, I think there's some
nominal license fee to use it on Windows.
Thus endeth my spiel -

RE: [PHP] Set Global Variables
Well, on unix, you could use the (still experimental, according to the docs) shared memory functions: http://php.he.net/manual/en/ref.shmop.php There's also the apparently more mature, but less portable semaphore/shared memory functions (also Unix only) here: http://php.he.net/manual/en/ref.sem.php I've never used either of these. Maybe you could explain what you're trying to do a bit more (and what platform you're on). I can't see where loading separate copies of the variables would be much of a memory issue, unless you have large numbers of variables, very long strings stored there, and hundreds of apache child processes. - steve At 2:52 PM -0400 4/11/02, [EMAIL PROTECTED] wrote: >If I do that, won't the data that I fetch be duplicated in memory for each >user?

Syntax here is wrong; you don't need to declare function arguments
using var; only class variables need that. I'm uncertain what will
happen if you do this. I would expect that - if PHP's error reporting
were turned up to the maximum - it might give you a warning message.
So do either:
(1) Drop the 'var $HTTP_POST_VARS line;
OR do
(2)
clas Member{
var $HTTP_POST_VARS;
function vallidateForm (){
echo $this->HTTP_POST_VARS['frmUsername'];
}
}
Although option (2) would require rewriting the code below.
Also I assume that the 'clas Member{' line is just a typo, and your
actual code says 'class Member{'...

If you are using an old (any PHP3.x, and I think some early betas of
PHP4) version of PHP, you need to turn 'track_vars' on to enable
$HTTP_POST_VARS and other $HTTP_xxx_VARS arrays. If that's the case -
and you can't upgrade immediately - you need to turn track_vars on in
httpd.conf, php.ini, or .htaccess (whatever's appropriate in your
setup).
Hope that helps -

Re: [PHP] Reg ex help-Removing extra blank spaces before HTMLoutput
One way to do it is:
$NewString = ereg_replace('[[:space:]]+', ' ', $String);
There are also ways to do it with preg functions that are slightly
more efficient; see the pcre docs. And, the standard (AFAIK)
reference book for regular expressions is O'Reilly's 'Mastering

Re: [PHP] last entry in mysql
This may be stating the obvious, but: (1) Does your table have an auto_increment column? (2) If so, did a previous query in the program - for example, an INSERT - generate a new record with an auto_incremented value? AFAIK, mysql_insert_id() won't return the last id unless you have a previous query in that same program that INSERTED/UPDATED an auto_incremented column. If you want the maximum value of the column, you can always issue the query: SELECT max(your_auto_incremented_column_name_here) FROM your_table_name_here At 10:30 AM -0600 12/12/01, Yoed Anis wrote: >hey guys, > >quick question I'm having trouble finding an answer too. >In a mysql database, how can I select that last row entry.

Re: [PHP] $PHP_SELF not working -please help
Is the code below in a function? If so, you'll have to globalize $PHP_SELF:
function your_function() {
global $PHP_SELF;
...
echo $PHP_SELF;
..
}
alternatively, you could do
function your_function() {
...
echo $GLOBALS['PHP_SELF'];
..
}
To the best of my knowledge, PHP_SELF is set regardless of the
register_globals configuration setting, but I'm not 100% sure.

Use strlen(). For example:

if (strlen($String) > 20) {
$String = substr($String, 0, 17).'...';
}
In PHP4, you can use the substr_replace() function to replace the
third line in the example above:
$String = 'hi my name is';
if (strlen($String) > 20) {
$String = substr_replace($String, '...', 17);
}

If by 'spaces' you want to include tabs, newlines & stuff, you can also do:
if (!ereg("^[[:alnum:][:space:]_-]+$", $string)) { get outta here! }

Yes, you'll need the reset() there if you're looping through the
$HTTP_POST_VARS array more than once. However:
I take it that you were trying something like
echo $HTTP_POST_VARS[0];
? If so, you will indeed get the output 'array' if element 0 is an
array. As someone suggested, you can use the print_r() or var_dump()
functions (print_r, I think, is PHP4 only) to display it. You can
also do something like
...
if (is_array($HTTP_POST_VARS[0])) {
while (list($k,$v)=each($HTTP_POST_VARS[0])) {
echo '$HTTP_POST_VARS[0]', "[$k] = $v";
}
} else {
echo '$HTTP_POST_VARS[0] = ', $HTTP_POST_VARS[0];
}
...
In PHP3, POST/GET elements could only be one dimensional arrays, at
most. In PHP4, though, these can have 2+ dimensions, so for maximum
generality you'd have to have somewhat more complex code than this.

Are you talking about a specific row in the mySQL result set? If so,
use the mysql_result() function. However, this function only returns
one column at a time, so you'd have to loop, something like:
$i=0;
unset($row);
while ($Value = mysql_result($ResultId, 4, $i)) {
$row[] = $Value;
$i++;
}
Note I used row # 4 in the mysql_result() call instead of 5, since
(I'm 89% sure) row counts are 0-based.
I'm also pretty sure you CANNOT use mysql_result() to position to the
desired row, then use mysql_fetch_array() or a similar function to
fetch the whole row.
See
http://www.php.net/manual/en/function.mysql-result.php
for more info.
You may be able to use the mysql LIMIT functionality to do what you want:
$Query = 'SELECT * FROM table ORDER BY name LIMIT 4,1';
This grabs the fifth (again, row counts are 0-based) row. See
http://www.mysql.com/doc/S/E/SELECT.html
Incidentally, your original statement
$row[5]=mysql_fetch_row($result);
would simply create a 1-element array $row, with the array index 5.
If this was your first fetch statement, $row[5] would still contain
the first row of the result set.

As far as I know, there are no ill effects from doing this; I do it

(I have the top form on a PHP3-based setup).
On the occasion when I need to redirect the user to another page

Re: [PHP] PHP3
The PHP version plays no part in this, since the SELECT statement below is passed directly to MySQL. And, yes, this should work on that MySQL version - it's a pretty simple statement. Were you experiencing a problem with it? If so, post the relevant PHP code & the error message you're getting. The only thing that might conceivably be a problem is the table alias syntax. What you have _should_ work, but you could also try Select a.field, b.field from table_one AS a, table_two AS b where a.id = b.id - steve At 1:48 PM -1000 6/20/01, William Poarch wrote: >Hi, > >Does "Select a.field, b.field from table_one a, table_two b where a.id = >b.id" work in PHP3/MySQL 3.22.32? > >Client's running PHP3, and I'm on 4. > >thanks. > - - - - - - - - - - > Scott Poarch > www.globalhost.com > - - - - - - - - - - -- +-- Factoid: Of the 100 largest economies in the world, 51 are --+ | Steve Edberg University of California, Davis | | [EMAIL PROTECTED] Computer Consultant | | http://aesric.ucdavis.edu/ http://pgfsun.ucdavis.edu/ | +--- corporations -- http://www.ips-dc.org/reports/top200text.htm ---+ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Re: [PHP] split() function
You don't need a character class here (signified by [] brackets); you can use

As you can see, this is identical to ReDucTor's solution, except that
the brackets are omitted. Character classes only work for single
characters, not multiple character strings like '//'.

This line fetches the first row and moves the pointer to the next
row. You then proceed to ignore the results of the first row! Just
delete this line, and you'll be happy.

[PHP] Re: string formatting help
In the original message below, did you mean that you're actually
SEEING the tags in the output? If so, there may be a conversion
with htmlentities() going on somewhere that converts the tags to
<br> (so they are displayed instead of being interpreted).
If you replaced the 's with spaces or newlines, the output
_should_ all be on one line, since HTML considers ALL strings of
whitespace (tabs, newlines, returns, spaces) to be a single space. If
you replaced 's with newlines and you are getting the line breaks
still, your output may be in a ... block.

Or, more compactly:
echo str_replace('', '', $string);
This would only work if tags were lowercased; to handle mixed case,
you'd need to do
echo eregi_replace('', '', $string);

No, because $value is a copy the current array element, not simply a
pointer to it. Furthermore, if I understand the documentation (see
below) correctly, this construct (using the $variables array from
above) -
$i = 0;
foreach ($variables as $value)
{
$variables[$i] =AddSlashes( strip_tags($value));
$i++;
}
- will not work either, since foreach() operates a COPY of the array.
From the docs at
http://www.php.net/manual/en/control-structures.foreach.php :
Note: When foreach first starts executing, the internal array pointer
is automatically reset to the first element of the array. This means
that you do not need to call reset() before a foreach loop.
Note: Also note that foreach operates on a copy of the specified
array, not the array itself, therefore the array pointer is not
modified as with the each() construct and changes to the array
element returned are not reflected in the original array.

Re: [PHP] Name of an array???
Not quite sure what you're getting at here. As you discovered, if you have
$Thing = array(5,6,7,8);
and you 'echo $Thing;' you get 'Array.' However, in this case, you
know the variable name already - $Thing!
Are you thinking more along these lines:
$ArrayName = 'Thing';
$$ArrayName = array(5,6,7,8);
now,
echo $ArrayName;==> Thing
echo $$ArrayName; ==> Array
echo ${$ArrayName}[0]; ==> 5
See

for more info.

Re: [PHP] sorting results of opendir()
Here's one way:
$dir = opendir('.');
unset($FileList);
while ($file=readdir($dir)) {
if($file!= '.' && $file != '..')
{
$FileList[] = $file;
}
}
sort $FileList;
reset($FileList);
while(list(, $F) = each($FileList)) {
echo "$F\n";
}
If you're using PHP4, you can replace everything after the
sort($FileList) with the more compact:
foreach($FileList as $F) { echo "$F\n"; }
See

Re: [PHP] Help..Parse error
My guess is that you have the short_open_tags option on in your PHP3 config, but off in your PHP4 config. If it's off, PHP will only recognize the tags, not . PHP config params can be set in php.ini, .htaccess, and/or Apache httpd.conf files. Scroll down to short_open_tag in http://www.php.net/manual/en/configuration.php#configuration.file for more info. You can also check your config via the phpinfo() function. - steve At 1:45 AM -0400 7/20/01, Jack Sasportas wrote: >I have some code that runs under php3, but under 4 I get a parse error >on this specific line, can't figure out how to resolve it. > >the code looks like this > > > > >the error is in the middle line which is the end of a condition... > >Thanks in advance... > > >-- >___ >Jack Sasportas >Innovative Internet Solutions >Phone 305.665.2500 >Fax 305.665.2551 >www.innovativeinternet.com >www.web56.net > -- +-- Factoid: Of the 100 largest economies in the world, 51 are --+ | Steve Edberg University of California, Davis | | [EMAIL PROTECTED] Computer Consultant | | http://aesric.ucdavis.edu/ http://pgfsun.ucdavis.edu/ | +--- corporations -- http://www.ips-dc.org/reports/top200text.htm ---+ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
Re: [PHP] Mysterious MYSQL Error..
Do you know if you've even made a valid database connection? Try echoing $this->database as well. If that is null, you haven't connected to your database; perhaps the username, password and or permissions were changed, so that you're unable to connect from your PHP program. - steve At 9:47 AM -0400 7/22/01, Greg Schnippel wrote: >I'm stumped on this one..

Re: [PHP] Using $$ to access a variable
I'm not sure that your construct will work; however, you could always do
echo $HTTP_POST_VARS[$table_array[$iCnt][0]];
in place of 'echo $$var' or
$var = 'HTTP_POST_VARS';
echo ${$var}[$table_array[$iCnt][0]];
When using variable variables, the array index - here, 'ld_val' might
not be interpreted correctly; I'm guessing that PHP is looking for a
variable named 'HTTP_POST_VARS["ld_val"]', not an element of the
HTTP_POST_VARS array. More info is at
http://www.php.net/manual/en/language.variables.variable.php
On the other hand, are you absolutely sure that something (other than
whitespace) is actually IN $HTTP_POST_VARS['ld_val'] ??
