This should be preg_match('/.../i', $_POST['website'])

your regex should look something like this.

^((ftp|(http(s)?))://)?(\.?([a-z0-9-]+))+\.[a-z]{2,6}(:[0-9]{1,5})?(/[a-zA-Z0-9.,;\?|\'+&%\$#=~_-]+)*$

So, put it all together and it should look like this.

<?php

$url = "...PUT YOUR TEST URL HERE...";

if ( preg_match('!^((ftp|(http(s)?))://)?(\.?([a-z0-9-]+))+\.[a-z]{2,6}(:[0-9]{1,5})?(/[a-zA-Z0-9.,;\?|\'+&%\$#=~_-]+)*$!i', $url) ) {
	echo "Matched";
} else {
	echo "Did not match";
}
