If i were to put something like [link]www.something.com[/link] how would i put whatever is between the tags into a variable.

[Demonslay]

Regex.

<?php
$text = '[link]Text here[/link][link]Text number twp[/link]';
preg_match_all('#\[link\]([^\[]+)\[/link\]#', $text, $results);
var_dump($results);
?>

$results[0] will contain an array of the full matches, and $results[1] will contain an array of the text between the tags.

but that didnt work
i just looking to store whatever is inbetween those tags in a variable.

$var = $results[1];

?

[Hip Hop Artist]

it didnt work.

Then what did it do...
C'mon, you can't be so vague with your results.

Use var_dump() or print_r() on the result set and you'll what it looks like. As I said, the second index (or in arrays terms, $result[1]) will be all matches of what is captured between those tags. It will come with as many results as it finds, so in the example I gave you, $result[1][0] will read 'Text here', and $result[1][1] will read 'Text number twp' (noticed my typo there, lol).

ok well i didnt know it had to be $result[1][0] you just said to put $result[1]but this is for a forum so how would i know how many links they put......i wouldnt know how many arrays to echo or whatever.......

[rc69]

All the results you want will be in $result[1]. Just loop through that array or call count($result[1]) and that will return how many there are.

Um, no I didn't.

As bolded above, I told you it could contain an array of the results.

And an alternative to rc's suggestion of using count() on the result array, you can also capture the return from preg_match_all() into a variable, as it returns the number of results it matched.
