Really stuck on what seems to be something simple. I have a chatbox/shoutbox where there may be arbitrary URLs entered. I want to find each individual URL (separated by spaces) and wrap it in tags.

Example: Harry you're a http://google.com wizard! = Harry you're a $lhttp://google.com$l wizard!

Example: Harry you're a http://www.google.com wizard! = Harry you're a $lhttp://www.google.com$l wizard!

Example: Harry you're a www.google.com wizard! = Harry you're a $lwww.google.com$l wizard!

Sorry if this is a daft question; I’m just trying to make something work and I’m no php expert 🙁

    There is an interesting article about a URL regular expression. In PHP this would look like:

    $pattern = "/(?i)\b((?:https?:\/\/|www\d{0,3}[.]|[a-z0-9.\-]+[.][a-z]{2,4}\/)(?:[^\s()<>]+|\(([^\s()<>]+|(\([^\s()<>]+\)))*\))+(?:\(([^\s()<>]+|(\([^\s()<>]+\)))*\)|[^\s`!()\[\]{};:'\".,<>?«»“”‘’]))/";

$inp = "Harry you're a http://google.com wizard!";
$text = preg_replace($pattern, "[supertag]$1[/supertag]", $inp);

    And of course replace [supertag] and [/supertag] with the appropriate values.
