PHP URL Tag Formatting

By Chris 'autolycus' Bokitch

The url tags on this site and on the Chatbear message board system (which most of my tags are based on) use this format:

    url=http://www.url.com/[url description]url

This is parsed from a block of text ($string) using the following PHP code:

$string = preg_replace("/url=(.*?)\[/", "<a href=\"\\1\">", $string);
$string = ereg_replace("\]url", "</a>", $string);

So, you can do something like this ...

    url=http://collective.valve-erc.com/[VERC Collective]url
