This will not work, ini_set cannot mess with magic_quotes setting,
.htaccess is the prime option for temporarily changing this setting, as
per the example provided by Zeev.

More precisely, it can change the setting but your PHP code will be executed
after the magic quotes work has already completed.

Here's an example (a hack) which may help you get going :
print getFutureDate('2001-03-28',4); // 2001-04-01
function getFutureDate($date,$days,$format='Y-m-d')
{
list($year,$month,$day) = explode('-', $date);
$timestamp = mktime(0,0,0, $month, $day, $year);
$secs = ($days * 86400);
return date($format,$timestamp+$secs);
}

I would like to get rid of \n characters unless there
are two or more in a row. So for example if there
is a long email formatted like we do here with
line break I want to remove the line breaks so
text can be wrapped by a browser, but also show
paragraph breaks where necessary. This is what
I have:
$string_new = str_replace("\n", "", $string);
How can I augment this to not replace:
\n
\n
Thanks.

The Perl-compatible regular expressions support lookahead and look behind:
$str = 'abcdefabcaadd';
echo "$str\n";
$str = preg_replace("/(?<!a)a(?!a)/", "-", $str);
echo "$str\n";
will display this:
abcdefabcaadd
-bcdef-bcaadd

Man, that went right over my head. Is there a description of
how this works anywhere? Thanks for help in any case.

Or you could just do this:
<?php
$str = "abc\ndefg\n\nxyzpqr\njklmno";
$str = ereg_replace("([^\n])\n([^\n])", "\\1 \\2", $str);
echo $str;
?>
That should give you:
abc defg\n\nxyzpqr jklmno
Works by replacing any \n with a space, as long as that \n is not next to
another \n.

The Regular Expression part of the online PHP manual has a lot of information
(http://www.php.net/manual/en/ref.pcre.php) but it does tend to assume you
already know what you need to do.
Basically, the regular expression in there matches any "a" where the character
before isn't an "a" (?<!a) and the character after isn't an a (?!a). Any
matched characters are replaced with hyphens.
For your needs, '/(?<!\n)\n(?!\n)/m' should work (the /m turns on multi-line
support, which is necessary since we're working with line breaking characters).
Note that you'll need to escape those backslashes in PHP if you use
doublequotes.
That almost works. The two \n in a row are on new lines.
So it's
\n
\n
intead of \n\n. If that makes any sense.

No, that doesn't make any sense whatsoever :)
A \n *is* a new line. I can only guess you're getting confused because
there's \r's as well as \n's in the string. Try this:
<?php
$str = "abc\r\ndefg\r\n\r\nxyzpqr\r\njklmno";
$str = ereg_replace("([^\r\n])\r\n([^\r\n])", "\\1 \\2", $str);
echo $str;
?>
Or alternatively:
<?php
$str = "abc\r\ndefg\r\n\r\nxyzpqr\r\njklmno";
$str = ereg_replace("\r", "", $str);
$str = ereg_replace("([^\n])\n([^\n])", "\\1 \\2", $str);
echo $str;
?>
A CR is a carriage return, a LF is a line feed or newline. \r = CR, \n = LF.
Unix files use only LF (\n) for new lines, whereas MS DOS/Windows uses CRLF
(\r\n) and Mac uses just CR (\r).

Ok now I'm really being a pest. Your code works on your
example but not on mine. I can't figure out why. But I really
appreciate the help so far from Chris and Simon so thanks.
Here is my example and what happens when I use your
code. I tried it by pasting text into a textarea part of a
form and also just having it in a plain text file (Windows system).
(I just tried creating a file on Unix also, same result.)
Removes the line breaks but also the multiples for paragraphs.
This isn't very important, more of a curiosity.

original text:
This is a story
of how the West was won.
Not about the Brady bunch
but how those guys with guns
somehow won.
I don't know who won, but
I do know the West was won.
So the West is number one.
Yay.
-----------
returned from your code:

I just tried with your text and it reformats it correctly for me...
Here's what I have got:
<html>
<body>
<form method=post>
<textarea name="str" cols=50 rows=10></textarea><br>
<input type=submit>
</form>
<hr><pre>
<?php
$str = ereg_replace("([^\r\n])\r\n([^\r\n])", "\\1 \\2", $str);
echo $str;
?>
</pre>
</body>
</html>
I pasted your text into the textarea and submitted it:
This is a story
of how the West was won.
Not about the Brady bunch
but how those guys with guns
somehow won.
I don't know who won, but
I do know the West was won.
So the West is number one.
Yay.
And it outputted:
This is a story of how the West was won. Not about the Brady bunch but how
those guys with guns somehow won.
I don\'t know who won, but I do know the West was won. So the West is number
one.
Yay.
(Just need to run it through stripslashes() to fix the don\'t.)
Does this not work for you? Some troubleshooting ideas:
<?php
$str = ereg_replace("\r", "CR", $str); // replace CRs with "CR"
$str = ereg_replace("\n", "LF", $str); // replace LFs with "LF"
?>
<?php
echo urlencode($str); // may help to highlight any special characters
in the string
?>
Hope this helps

Isn't this a bit more legible:
if (!empty($var))
empty() fails when $var == 0

No, it's not possible. The safest approach is to assume the user doesn't have a
plugin and then use JavaScript to enable a plugin. In certain cases, there are
plugin specific tricks you could play in a detection script (e.g. QuickTime
allows a QTSRC attribute which overrides the SRC value - SRC="somefile"
QTSRC="plugin_check.php?HasQT=1&filename=somefile"). For the rest, you'll need
to use JavaScript.
This is complicated by the way Microsoft broke Netscape's plugins object - on
netscape, you can iterate over that list very easily. IE has the object, but
it's always empty. (You can use VBScript to attempt to create an object of that
class and then trap the error if it fails, but that's not particularly elegant)
Afternoon All,
Been running through archives and posts throughout the net.
Hopin ta find an answer. Looks like the questions been asked,
but no public answer has been made.
I'm using PhpLib's Template code. ( just pulled the file and
modified it a minor bit ) The problem I'm having is when I create
a dynamic page with the Template class, any php within that
page is not being parsed by the webserver. If you visit:
http://www.kyndig.com/listings and look at the page source,
you'll see the php code to call the banner code in. Any pointers
in how to go about fixing this is much appreciated.

Ok, I'm trying to open a socket connection to port 23 (telnet)... the
script just seems to hang on connect... though I can connect and talk
with ports 25 (smtp), port 80 (http), port 110 (pop3) and port 443 (https)
so the code isn't too bad... Is there something special about the telnet
port?

Don't quit working with filemaker entirely. It has many advantages, such
being great for quick prototyping. Just don't waste time trying to use FM
as a web backend, 'cuz that gets ugly quick. A Mac user can fulfill that
need with MySQL/PHP (or PostgresSQL/PHP) just fine. I know of at least
two options for doing this:
1) OS X
2) using one of the Linux distros for Mac (ex. LinuxPPC, YellowDogLinux,
SuSe)
Both options are very cheap to try, and offer slightly different
advantages, so no harm in trying out both. Plan on setting aside 1GB or so
for a Linux partition, for which you get a dual-boot Mac--giving you all
the advantages of Mac PLUS all the advantages of Linux in one box. Not
bad, eh?

Hi all,
I'm a little concerned as to how many times some of the scripts I've been
working on are querying a database: Some are making up to 4 or 5 queries
each. Should this give me any cause for concern?
I've only ever been unable to connect to the database once (other than
through script error), and that's when I was using a persistent connection.
So, I guess my question is, is there a recommended maximum number of queries
I should be working around? (MySQL).
Thanks,
James.
Could some one please have a look thru my code and tell me why it creates a new record
instead of updating the record?
What this script is suposed to do is show a HTML form .. then once the user fills it
out it then shows another form which echo's the values inputted in the first so the
user can update if they made a mistake .. it does everything right .. up until the
user clicks on update ... where instead of updating the record it creates a new one ..
Any sussestions/Help would be greatful

Peter,
In case "AAA" When $submit is set, you will always get an an insert; you
have a mysql_query executing.
In case "BBB" you are only assigning the SQL statement to $result, I didn't
look further to see where it executes. It really doesn't matter because
case "AAA" will always fire first.
Can you structure your flow so that, depending on your conditions you
assign the SQL statement to a variable, such as $sql_string, and then at
the end of your conditions execute $result = mysql_query( $sql_string ); ?
This also looks like a scenario where having a good hard look at using
switch ... case .. break. I've really liked it for control structures
involving buttons.
You may also want to consider redisplaying your input page with a flag
identifying the missing or incorrect values. Julie Meloni has a very nice
example of this at http://www.thickbook.com
Hope you are having lovely weather. Our forecast tonight is snow, followed
by ice pellets, freezing rain, rain and then back to snow. All that's
missing is the sunshine!

The query flagged by if ($submit) will always fire first, and it appears
you will always have a $name value as well. I believe it's actually firing
twice in some scenarios - runs the insert and then immediately updates.
Will $submit contain different values? Then
switch ( $submit )
{
case "update":
$sql = "update blah blah ....";
break;
case "new":
$sql = "insert into blah blah ...";
break;
default:
echo "No value to process for submit";
unset( $sql );
}
if isset( $submit )
{
$result = mysql_query( $sql );
.... and so forth ..
}
With this structure you can use an array to hold the value of your buttons,
such as $action[ ], in which case the switch statement is "switch(
$action[0] )"
Cheers - Miles

Use mysql_error() after your unsuccessful call to mysql_connect to return
a mysql error string

Hehe, this wouldn't work if the connect was unsuccessful. You can always
get an mysql error string after a successful call to mysql_connect. Look
into Paul DuBois book and it should be very clear.

George,
1. Is this a brand new project, or were you connecting before, on your web
pages? If the latter, what changed?
2. **IMPORTANT** Have you also run phpinfo() and confirmed that you have
mysql support installed? **IMPORTANT**
3. Did you stop and restart Apache?
4. Have you tried a minimal page - just connecting and echoing the result?
or with a built-in die message?
5. Is this a self-hosted server, or someone elses? What name combinations
of localhost, username and password have you played with? What name is
mysql running under?
I'll also confess I've given up on .rpms for all of mysql, apache and php.
It's fairly quick to build them from source, and you have full control over
where things are placed. Search for something like "LAMP Apache" and that
will turn up the necessary tutorials.
This probably hasn't been much direct help, but maybe it'll get you going.
It's not fun, but I've slowly learned to check basics first! (Like the
wire, when there's a network connectivity problem - sheepish grin.)

Hi,
I have PHP installed on a Win95 machine. What I'd like to do is to use
a PHP page that will create multiple HTML pages.
I guess that I can execute PHP.EXE multiple times, but was thinking that
this means that it's going thru the overhead of starting up PHP.EXE each
time. Is there any way to tell PHP.EXE to build multiple HTML pages,
i.e., kind of like a loop?
Jim
Jim,
PHP works with your server to generate the HTML output, so PHP is "running"
all the time, it's not like a CGI script. PHP code is embedded in your HTML
pages, so you can use it to control the generated HTML. You can turn it on
and off within the page. Carefully look at Chapter 1 Page 1 of the manual
"What is PHP?"
Then look at a couple of the tutorials at www.thickbook.com, WeberDev,
Devshed, and so on. The concept will become clearer. From there on, take it
away; it's powerful, flexible and occasionally frustrating and embarrassing
(like all languages).
So you can have little pages full of buttons or links which open up other
pages, or sometimes a lot of PHP script generating relatively few lines of
code, all depending on various conditions.

Hi,
This is probably a no brainer for the math wizards out there.
Can anyone see how the folowing code ( originally posted on
phpbuilder titled "RE: dynamic corners" as a responce to Rasmus's
article on image creation with php & GD :
http://www.phpbuilder.com/annotate/message.php3?id=1003041 )
can be modified to change the "curve" of the arc.
I would like to be able to modify the code so it can display
and arc with a curve inbetween the arc the code produces now:
#################
# ##
# #####
# ########
# ##########
# ############
# ##############
# ###############
#################
#################
and a triange like below:
#################
# ##
# ###
# ####
# #####
# ######
# #######
# ########
# #########
# ##########
# ###########
# ############
# #############
# ##############
# ###############
#################
( pretend this image is the same
height as the one above ;)
In otherwords I would like to be able to modify
the "height" of the arc ( not to be confused with
the height of the image ) as one is able to modify
the height of the arc produced using the GD ImageArc()
function.
You may be wondering why I am not using the
ImageArc() function in the first place. Well
check it out and see... this code produces
a beautifully antialiassed curve, and the
ImageArc() does not.
Looking forward to your ideas.
Thanks,
Sam

Did you check the documentation, or the sample ini file? According to the
docs,
sendmail_from string
Which "From:" mail address should be used in mail sent from PHP under

It works also under GNU/Linux. I haven't tested it under Unix. The
comments in php.ini may be wrong.

How can I get php to print a long string and ignore
any of the characters in the string?
ie:
$string = "so<me'strin^g";
print $string;
isn't there some kind of command to use that keeps
the string exactly as it is?

Clayton,
Have a look at http://www.php.net/manual/en/function.addslashes.php
I've not used them, there are also references to stripslashes, you may need
to experiment a bit.

Have a quick look at
http://www.php.net/manual/en/control-structures.switch.php
which has some user notes which are possibly useful over and above the
actual documentation.

I'm playing aruond with the switch statement trying to get one to work for
$submit
I have 2 forms on the one page (only one displays at a time) 1 is for
creating a new record in my data base the other is for updating/changing
values from the first form should there be any. So i want it to switch

OK. Suppose the possible values for $submit are 'insert' and 'update'. [I
assume those are values _you_ can assign to a submit button]
Then
switch($submit) {
case 'insert':
// Your insert stuff here
break; //So it doesn't fall through to the next case
case 'update:
// Your update stuff here
break;
case default:
// The page has somehow been called without a value (or an
// inappropriate value) for submit
// Error handling or whatever here
}
Does that make it clearer? or muddier :-)

I have created a config.php3 to store the connection of the database and
some constant variable. Then, I created the other file functions.php3 and
inculde config.php3 into this file for function.phps3 should use some
variables inside the file config.php3. However, I don't know why all the
variable cannot display in the function.php3.
would anyone please to tell me what is the reason and how I can solve it?

You may need to declare the variables global within the function, or pass
them as arguments to the function.

Am i wrong or php does not support mysql_info() function ?
Is there plans to support it?
thanks in advance!
Okay, I got a bit of a curley one that I havent been able to solve by
looking at the archives and in the manual. Its kind of a PHP/Apache question.
I have a system where a user logs in through .htaccess, it queries my mysql
database, sets a cookie which logs their username and access level number.
What I want to be able to do it this.......... Give the option to "Log Out"
which will clear the cookie, and also make htaccess re-request a login.
Once it logs in again, the current scripts do their thang and log the new
user in.
Is there any direction anyone can point me to start looking cause I have a
feeling im off the track on what im searching for in TFM and in TFA.

Im trying to build a user login system, and when there is a new user, I need
to validate that they are usign using word characters ([0-9A-Za-z_] or
\w)... I have TRIED MANY different regular expressions to test this, but
none work. This seems so simple but I am missing something. I need a
expression that returs true ONLY if ALL the characters match \w .... Any
help would be appreciated.

Assuming you only want letters, numbers, underscores or hyphens. If you
really want \w you would need to use preg instead of ereg, and then you need
PCRE support in PHP. Or you could use ereg's character classes, I think the
pattern would look like: "[^[:alphanum:]]". However you are probably better
off using an explicit set of characters as I have shown, so that it is
obvious what is and is not allowed.

ok, that was my problem.... Was using ereg... All the places I read about
how to do regular expressions (book, online...) did NOT clarify that \w and
such would need preg.. Thanks!

No prob - yeah, \w is a Perl feature :)
(preg = PCRE = Perl Compatible Regular Expressions)

Greetings!
Is there any equivalent code for (JavaScript) <a
href=JavaScript:history-back(1)>Back Button</a> in php?
This works as back button on the menu bar.
Looking forward to hearing from you.
regards,
DT
The problem with this (the javascript history) is it bites on frames.
One thing you could do is
print("<a href=\"" . $HTTP_REFERER . "\">Go back</a>");
or some such. At least then you could do referer sanity checking to make
sure you didn't dump the user somewhere nonsensical (if they've bookmarked
something in the middle of your site.

Yes, but it works differently. If the user typed in the URL of your page
(instead of clicking a link) then you can't go back from PHP, so you need to
be careful. Here's some sample code:
<?php
$referer = getenv("HTTP_REFERER");
if ($referer)
{
$url = $referer;
}
else
{
// can't go back... try JS instead
$url = "javascript:history.back()";
}
echo "<a href=\"$url\">Back Button</a>";
?>

I have php4 running under Apache. Under that apache I have several
<VirtualHost>s. I want to set to some of the PHP.INI values under
one of those hosts. So far I have tried the following values in
my httpd.conf file:
1) include_path "/my/phpinc/path"
2) php_include_path "/my/phpinc/path"
3) php3_include_path "/my/phpinc/path"
4) php4_include_path "/my/phpinc/path"
None of them have worked - I can't even restart Apache with them in place.
"/my/phpinc/path" definitely exists.
What am I doing wrong?
