Regular expression - URL validator

Hello,

I found this regular expression on a web site.
It is basicaly an URL validator.

I'm trying to implement this in my web site, but i receive errors.

I think this is a PERL REGEX so what should i do to make it work in php?

$valid =
(preg_match('^((((H|h)(T|t)|(F|f))(T|t)(P|p)((S|s)?))\://)?(www.|[a-zA-Z0-9]
.)[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,6}(\:[0-9]{1,5})*(/($|[a-zA-Z0-9\.\,\;\?\'\\\
+&amp;%\$#\=~_\-]+))*$', $_POST['website']));

if ($valido == 0) {
    something here;
    }
else {
    something else here;
    }

Thanks a lot in advance,
Wagner.
