[thelist] [php] preg_replace text links?

[kris burford]

hi,

i'm trying to get my head around some regex in php which i've lifted (with 
only minor understanding) from "mastering regex expressions".

what i'm trying to do is scan user submitted text (parsed through 
htmlspecialchars) pick out any links and link 'em up.

the starting pattern (from the book) is at 
http://www.midtempo.net/regex.html but it just gives me "Warning: Delimiter 
must not be alphanumeric or backslash". i've tried countless additions of 
backslashes and googled for help, all to no avail...

has anyone done this before? if so, where am i going wrong?

tia
