[PHP] preg_replace pains
Hi all,
I've been having a wonderful night trying to solve this one, but I'm going
to throw in the towel and see if anyone else can shed some light on it. The
scenerio is quite simple, I'm parsing some form input from a user and
looking for the following:
[details]...[/details]
where the can be any number of characters.
All I want to do is remove the whole section, including the [details] part.
So far I've got this working:
$message = preg_replace('\[details\].*?', , $message);
Which manages to find the opening tags (and remove them) but as soon as I
try to capture the closing tag (and all inbetween) it goes horribly wrong.
My last attempt looked like this:
$message = preg_replace('\[details\].*?\[/details\]', , $message);
This fails miserably. I'm fresh out of ideas and don't know enough about
regular expressions to be able to complete this task without some
assistance. ANY comments welcome!
Cheers,
Richard

Wouldn't you want to use preg_match() before you replace it?

In this instance, no I don't think so. I've already performed the task I needed with the tags in question and this is merely a clean-up to purge out the string now I'm done with it. Except of course it's not working yet :) Cheers, Richard -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

You didn't state what you want to get out of this exercise.
To squash the detail tags and everything between them:
$msg = preg_replace('/\[details][^[]*\[\/details]/', '', $msg);
To convert the [] delimiters to delimiters:
$msg = preg_replace('/\[(\/)?details]/', \\1 . 'details', $msg);
To drop everything outside the details:
$msg = preg_replace('/.*(\[details][^[]*\[\/details]).*/', \\1, $msg);
Enjoy,

Re: [PHP] preg_replace pains
try $str = preg_replace(|\[details\].*?\[/details\]|si,, $str); drop the i if you want it case sensitive.
