preg_replace() problem

[Phoenix_Down]

I'm having a problem getting this to work:

$gbcode = preg_replace("<a href=\"(.*?)\" target=\"_new\">(.*?)</a>", "{url=\\1}\\2{/url}", $gbcode);
$gbcode = preg_replace("<a href=\"(.*?)\" target=\"_new\">(.*?)</a>", "{url]\\1[/url}", $gbcode);
$gbcode = preg_replace("<a href=\"mailto:(.*?)\">(.*?)</a>", "{email}\\1{/email}", $gbcode);

It just shows a blank textarea when I use it.

Edit: { } = [ ]

Check this page http://www.php.net/manual/en/function.preg-replace.php The patterns in the preg function line need to be delimited by /
