Hi Paul,
Glad you got it working. I would add one note: I don't know if this is
what your actual code contains or if it's just in your emails, but not
quoting string indices in arrays is a Bad Idea (TM). i.e. I'd
recommend avoiding the use of something like $_SERVER[PATH_INFO] and
instead use $_SERVER['PATH_INFO']. While the unquoted version will
work much of the time, it's untrustworthy. In this case, PHP sees the
label PATH_INFO and looks for a constant named PATH_INFO. If it
doesn't find one, then it interprets the label as a string--which
allows things to work. However, if at some point you include code
which does a define('PATH_INFO', 'foo'); then what PHP will see is
$_SERVER['foo'], which probably isn't what you wanted.
This example is of course a little contrived, but unless you know that
there is a constant defined with the value you're using, and you want
to use that as your array index, then you should always quote string
array indices.
For more information check out
http://www.php.net/manual/en/language.types.array.php#language.types.array.donts
Of course, if you just left out the quotes for the purposes of posting
then you may happily ignore this message and carry on. :)
Cheers (I'm done butting in now),

Hi Paul,
For that, you use curly braces inside strings:
$line = "{$array['name']}{$array['address']}";

Impossible to say without know what the error says. :) Anyway, if that
code is cut-and-pasted, then 'foreach' should have no space in it. That
would cause a parse error. Otherwise, you could be getting a Notice
if you're actually passing something in via method="GET" but checking
the $_POST array instead.

This function definition should not be inside the foreach(), since the
second time the loop executes, it will stop and tell you that you can't
redeclare an already defined function (and it was defined on the first
loop).
I haven't checked the rest of it; try the above ideas and see if they
help.
Good luck,
Torben

You should quote the word 'attributes':
http://www.php.net/manual/en/language.types.array.php#language.types.array.donts
Sorry...that link might wrap. Anyway, I doubt that's the problem...

No idea. All I did was copy-paste your code and add a test definition
for the other vars, and I just got this:
[Script]
array('attributes' =>
array('height' => '"168" cm',
'weight' => '\'65\' kg')));
$singleProfileHTML = '';
$i = 1;
foreach ($profileArray[$i][attributes] as $key => $val) {
$singleProfileHTML .= $key . "=\"" . str_replace("'", ''',
str_replace('"', '"', $val)) . "\"\n";
}
print_r($singleProfileHTML);
?>
[Output]
Notice: Use of undefined constant attributes - assumed 'attributes' in
/home/torben/public_html/phptest/__phplist.html on line 36

I don't see anything wrong. Perhaps you have a non-printable control
character embedded in your code? Try copy-pasting the above code (but
quote that array key) and see if that helps. Also, check the code
before that line for unclosed quotes and braces/parens or other
problems; some parse errors can show up far from where they actually
occurred.
Other than that, without knowing anything else, it's hard to say off the
top of my head.

foreach ($SAVEVARS as $key => $value) {
$query = "update table set $key = '$value'";
}
Also, unless you have constants named 'headerimage' and
'backgroundimage', you should quote the array subscripts:
$SAVEVARS['headerimage'] = $_POST['headerimage'];
etc. See the manual for why:
http://www.php.net/manual/en/language.types.array.php#language.types.array.donts
Hope this helps,

Using lots of globals will make that harder, since it will mean that you cannot simply lift that function out and drop it into some other chunk of code without making sure that the new global space contains all those globals, and that they contain what you expect. This is called 'tightly-coupled' code. It's just harder to reuse. 'Loosely-coupled' code relied much less on the environment around it.

So, i would say that's an argument list, is it not? No, it's a configuration file. An argument list is the bit between the parentheses when you write a function call: $retval = some_func($this, $is, $the, $argument, $list); If your config file had all of those variables in an array or something, and you passed that array to your function, *that* would be an argument list. See below: config.php: 1, 'overall_summary' => 'Here is the summary', etc); ?> script.php: Problem solved. The only thing left which can conflict is the name $config, and you could solve that by calling it something you're sure nobody else will be using (maybe $_omh_config or something). Now, you can lift your config file and display_menu_html() function and drop them into pretty much any script and be much more sure that you won't have to crawl through all the code making sure there are no variable name conflicts. > The other way would be to write a function that obtains that from the > argument list. But as I see it, it's basically the same thing? NO? No, because say you want to use this function in another script. First you need to make sure that this new script isn't already using any globals with any of the names you want to use--otherwise, you'll have variable clashes--where you expect one thing to be in $logout, for instance, but the script is using the name $logout for something else, and the value isn't what you expect. > Class..

I searched using the terms 'list' and 'reply-to', and the thread was on the first page. But it depends on which archive you're searching, of course, and you didn't specify which one you are looking in.

Unfortunately, it is extremely limited and usually not worth the hassle. My suggestion would be to do something like this: have a page which shows a login form. The form posts back to itself (the same page). When there is no input, the script displays a blank login form. If there is input, the script attempts to validate the login data. If the data validates, the script somehow calls the next page (sends a redirect header, or include()s the code, or instantiates that page's class, etc...). If not, it redisplays the form, perhaps with some added information about what went wrong. It's important to note that nothing is ever sent to the browser until all needed information is known...that way, you always have the option to alter the output, or send a redirect header, or whatever.

The ); closes the printf(), but the next line continues on to attempt
to add more arguments. You would either need to do this:
$row['added'],
$row['q40']);
...or, better yet, something like this, so you aren't printing out the
whole table for each row in the results:
echo "
DATECOMMENTS\n
";
while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
echo "
{$row['time_stamp']}{$row['heading']}\n";
}
echo "
";
Hope this helps,

Whoops...replace 'time_stamp' with 'added' and 'heading' with 'q40',
of course. :)

Nope...it's working perfectly. mysql_fetch_array() returns an array.
foreach() operates on an array. What you have:
foreach (mysql_fetch_array($result) as $key => $article) {
//. . .
}
...is the same as saying this:
$arr = mysql_fetch_array($result);
foreach ($arr as $key => $article) {
//. . .
}
So it is iterating over the correct array (the returned row array)
instead of the array over which you want it to be iterating (the
array of rows).
Using the counter is probably your best bet. mysql_fetch_array() doesn't
return any information on which row it's currently returning.
Hope this clears it up a bit,

This is a good idea for a production machine, but for your development
environment, turning down error reporting is not a good idea. :) You
will kill yourself trying to track down subtle errors when they aren't
displayed.
Try checking your variables before using them:
if (isset($_GET['printout']) && $_GET['printout'] != 'yeah') {
// . . .
}

Unfortunately, that's not how PHP works...for one thing, the parser would need some kind of insight into when something next to a set of parentheses should be multiplied with the contents of the parens...:) FWIW, 9(9) means '9 * (9)' to me, but only on paper, and in the context of algebra. In the context of programming, I would typically read it as 'call the function named 9 with the argument 9'. The multiplication operator in PHP is *.

One idea:
header("Location: form.html");
With this one, you have to jump through some (admittedly not
difficult) hoops to get your data across the redirect (post it).
Another: Write a function to generate the form for you and call that.
Another: include("form.html"); exit();
With these two, the data is already available within the script, so it
will be easier to show what data was wrong/missing/et cetera. It's
usually easier to have the script which generates the form handle its
input as well, and then pass the resulting data whereever it needs to
go.

To modify the browser window content after you've already sent it,
you'd need to use one of client-side scripting, server push, or client
pull. In general, however, once PHP has sent output to the browser,
it's gone. The browser has it, and that's it. :)
Perhaps you could defer sending your content to the client until after
all your tests have passed and the script knows what it needs to
display?
Pardon if I've misunderstood the problem.

No, you're right. There are situations where you might want to use
these two functions, but this isn't one of them. Doesn't buy you a
thing in this situation. :) There are times I've found them useful,
though, although I won't contrive an example for you...you'll usually
know when you've found one.

I've gotten too darn many Haven't really seen this one flamed over on this list before, but maybe someone will step in an freak out later on. At any rate, you make the assumption here that Hungarian notation somehow inherently prevents errors. This is believed by some to be true, and by others, to be false. Hungarian notation does provide a set of tools for helping to prevent errors, true--but any proper coding convention does that. Past that, there is little to choose between them except personal preference. There are compelling arguments both for and against any given convention, and all have their adherents. In the end, one must be chosen--and for this project, one has been.

Check and initialize your input variables:
if (!isset($_GET['action'])) {
$action = '';
} else {
$action = $_GET['action'];
}
switch ($action) {
case 'something':
do_something();
break;
case 'something_else':
do_something_else();
break;
default:
echo "Unrecognized action given";
break;
}
If this is something you need to do for every page on your site, put
the if() check into an auto-prepended file or something.
Hope this helps,

If you want to maintain key order, use uasort(); if, however, you want
the array to be reindexed sequentially when you sort it, use usort():
http://www.php.net/manual/en/function.uasort.php
http://www.php.net/manual/en/function.usort.php
A short example (with the usual caveats about 'make sure you add error
checking):
104,
'first_name' => 'jack',
'last_name' => 'mother'),
array('loan_info' => 102,
'first_name' => 'jill',
'last_name' => 'brother'),
array('loan_info' => 108,
'first_name' => 'jim',
'last_name' => 'the'),
array('loan_info' => 107,
'first_name' => 'bob',
'last_name' => 'whole'),
array('loan_info' => 105,
'first_name' => 'alice',
'last_name' => 'fam'),
array('loan_info' => 103,
'first_name' => 'ellen',
'last_name' => 'damily'));
function cmp($a, $b) {
return strcmp($a['loan_info'], $b['loan_info']);
}
uasort($data, 'cmp');
print_r($data);
?>

Ah...in this case, the addslashes() is being called from within the
quotes, so it won't get called. In this case, I would suggest moving it
to the assignment above:
if (isset($var[$key]['Option']))
{
// Flag that we got one this time round.
$found = true;
// Get the translated name from $var.
$record[$var[$key]['Option']] = addslashes(trim($val));
}
...that way, you know it's been called on everything, and you don't
have to hunt around and change it in a bunch of places if you decide on
something else later on.
Cheers,
Torben

This is because when the form is first submitted, nothing has been
submitted, and thus $HTTP_POST_VARS['fname'] has no value. PHP is
simply warning you that you're trying to use an unitialized value.
Check the value first and you'll not have a problem with it:
If the first line looks odd, check out:
http://ca2.php.net/manual/en/language.expressions.php
You could just turn down your error reporting, but all that does is
hide from you the fact that you're using code with problems in it. You
should make sure the code executes in a development environment with
full error reporting on without warnings or notices, before you turn off
error display on the production box.

I think you might be getting confused with printf(). In that case, the
above would be:
printf("%s", $myString);
In any event, the choice will have no impact here. It simply appears
that the original poster has not got PHP installed properly, or else
the system is not configured to pass that page of through PHP.

Yes: your scripts need to be in plain text format, and was saving the formatting and other information along with the text--probably in some binary format that only Microsoft fully understands.

If you're sure you know what you're doing and my snide comment hasn't already put you off, the README indicates that you should be able to do it with cygwin (although I don't know what might have changed between the time that was written in 1998 and now).

Hi Tom,
There's only one thing you didn't try...see below:
> *The offending code:*
>
> }elseif($_REQUEST['add']){
> $desc = $_REQUEST['description'];
> str_replace("\r\n\r\n", "", $desc);
> str_replace("\r\n", "", $desc);
You need to assign the result of the replacement to something before you
can use it; arguments are not modified in place. So something like this:
$desc = str_replace("\r\n\r\n", "", $desc);
$desc = str_replace("\r\n", "", $desc);
This change shouild be all you need. However, if you want to be able to
accept input from other than windows users, you can do the whole thing
with strtr(). I haven't tested with preg_replace(), but I suspect that
using regexps for this would be overkill.
$trans = array("\n\n" => '',
"\n" => '',
"\r\r" => '',
"\r" => '',
"\r\n\r\n" => '',
"\r\n" => '');
$desc = strtr($desc, $trans);
Hope this helps,
Torben

I'm assuming with the above that you want to get the returned text from
the POST into a string for use instead of outputting it directly to the
browser; these changes should do that. Note: I haven't actually tested
it. :)

Well, this is a MySQL question, not a PHP question, but in PHP
you would do it like this:
mysql_query("DROP TABLE $table_name", $dbh);
Just make sure that the user PHP is running as has permission to
drop tables.
The MySQL manual page for DROP TABLE:
http://www.mysql.com/doc/en/DROP_TABLE.html

I agree with your point, but the adding of the second argument was more of a convenience thing than an admission that printing when calling a print statement was bad behaviour. :) Besides, it's more consistent since the introduction of var_export() with its similar abilities. As to your actual point (no more hair splitting): I agree. If the function has something to say, it's better to store that somehow and then use it when you need it. You get to determine when (and if) it gets output, and how. As someone else noted, you will sometimes find it necessary to break this rule (quick debugging statements, or functions whose purpose is to actually output something), but in general I wouldn't expect to see any benefit to having your functions doing their own output--beyond the initial convenience. For one thing, it can make effective use of templates a bloody pain.

Usually it's not much of an issue in PHP, though. Anyway, one of the better ways to deal with it is to loop over your input arrays and checking the values, something like this: You could also just turn down error_reporting to skip the NOTICE-level errors, but that's only really recommendable on a production box (where you should probably have display_errors off too)...but on a development server, hiding the problem is not likely to help in the long run. :) Hope this helps, Torben -- Torben Wilson <[EMAIL PROTECTED]>+1.604.709.0506 http://www.thebuttlesschaps.com http://www.inflatableeye.com http://www.hybrid17.com http://www.themainonmain.com - Boycott Starbucks! http://www.haidabuckscafe.com - -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Unless you're using arbitrary-precision math, the overhead of using
bcmod() is probably not worth it. In general you would just use
the modulus operator '%':
http://www.php.net/manual/en/language.operators.arithmetic.php
bcmod(a, b) is the arbitrary-precision version of a % b;
At any rate, what is the code doing that you're not expecting?

Separate the paths with semicolons or colons depending on your OS. You
can also check existing values using ini_get() and modify based on
that. I like to use something like the following:

What happens when you remove the single-quotes? You're currently
defining only one array value, with the key being the literal string
'$ODBC_RESULT'--when you probably want to be using the contents of
$ODBC_RESULT.
I haven't tested it, but it's the first thing I see.

The reason the variable was not being interpreted is that it was single-quoted, not double-quoted; variables are only interpolated inside double-quoted strings (and heredocs, but that's another story).

You've gotten the closest so far. :)
o Use quotes when the key is a string literal, and one of the
following is true: A) the array reference is not inside a string or
heredoc; or B) the array reference _is_ within a string or heredoc,
but is written using complex syntax (see below).
o If the key is an integer, you do not need quotes, but you may use
them if you wish.
o If the key is a constant, do not use quotes.
o If the key is a variable, single-quotes will prevent PHP from
interpreting the variable, and the result will not be what you
want. Use no quotes around variable keys (or double-quotes, but
that's pointless).
o If the key is some other kind of expression (function call, math
operation, etc) do not use quotes.
o Inside a double-quoted string or heredoc, you can opt to leave out
the quotes if you're using a string literal key.
o In general within strings and heredocs, you may want to adopt the
practice of always using the complex syntax to express array
references: $str = "This is a string {$array['user_name']}";
(Complex syntax isn't complex; just wrap the array reference
between a { and a }). Note that in this case, you again need the
quotes. Always using the complex syntax for array (and object)
referencing within strings will help prevent odd errors with the
arrays not being interpreted correctly, and indeed, if you want to
go any further than one level deep into an array or object within a
string, you must use the complex syntax.
I've spent some time this morning cleaning up the Array type page, so
hopefully some of this will be a bit clearer (at least, after the docs
get generated). There is also definitive information on the string
variable interpolation topic here:
http://www.php.net/manual/en/language.types.string.php
Hope this helps,

If you have GD version 2.0.1 or later and PHP 4.0.6 or later, try using
imagecopyresampled() instead of imagecopyresized(). You may get better

I have no idea where you folks have gotten the idea that asking how to get Javascript to interact with PHP would be particularly off-topic here.

It wouldn't be all that off-topic on a Javascript list either, but you'd still have a bunch of guys jumping up and yelling 'Ask on a PHP list, you loser', without actually providing any useful information.

It's slashes doubling up on you, you may have magic_quotes_gpc enabled in php.ini. magic_quotes_gpc is explained here: http://www.php.net/manual/en/ref.info.php#ini.magic-quotes-gpc You can check whether it's turned on with: http://www.php.net/get_magic_quotes_gpc http://www.php.net/get_magic_quotes_runtime So if that's the case, you could either disable magic_quotes in php.ini, or else test whether it's turned on and then decide whether to call addslashes().

Even better, you don't even need the fopen() and fclose() calls;
readfile() is doing this with just the filename.

This will cause $current to contain the number of bytes read from the
file, not the contents of the file.
http://www.php.net/readfile
Instead, use fopen()/fread(); or file()/implode(); or if you have PHP
4.3.x or newer, use file_get_contents().
http://www.php.net/file_get_contents
http://www.php.net/fopen
http://www.php.net/fread
http://www.php.net/file
http://www.php.net/implode

This will do two things you probably don't want: first, it will
repeatedly assign values to $index, overwriting it on each iteration;
and, it will always use the same value to do so, since
$HTTP_POST_VARS['$index'] has the single-quotes, which prevents PHP
from interpreting the contents of $index--so it's literally using the
string value '$index' instead of the value of the $index variable. You
probably want variable variables:
$$index = $HTTP_POST_VARS[$index];
...although even easier would be:
$$index = $value;

No offense, but why not just use exec() and its third argument, as
suggested and as you yourself noted? It does, in fact, do what you are
asking for. You are quite correct that system() is not the function you
want.
Just wondering. :)
