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\.\,\;\?\'\\\ +&%\$#\=~_\-]+))*$', $_POST['website']));

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"; }

if ($valido == 0) {

    something here;
    }

else {

    something else here;
    }

Thanks a lot in advance, Wagner.
