PHP validation/regex for URL

I've been looking for a simple regex for URL's, does anybody have one handy that works well? I didn't find one with the zend framework validation classes and have seen several implementations.



I used this on a few projects, I don't believe I've run into issues, but I'm sure it's not exhaustive:

$text = preg_replace(
  "'<a href=\"$1\" target=\"_blank\">$3</a>$4'",

Most of the random junk at the end is to deal with situations like in a sentence (to avoid matching the trailing period). I'm sure it could be cleaned up but since it worked. I've more or less just copied it over from project to project.
