Hi there..

I want to check a form entry if it is a "good" url.

There for I will make a pattern and check it with preg_match().
No I'm looking for a pattern to check for urls.

I took al look around the web and found the pattern below. but this
is not a "good" url.

PHP Code:

$website = "http://www.site.com";

$patroon4 = "~^https?://([-\w\.]+)+(:\d+)?(/([\w/_\.]*(\?\S+)?)?)?~";



if(!preg_match($patroon4, $website)) { echo"wrong"; } else { echo"good"; } 

where do I go wrong?

This may work:

function CheckValidUrl(strUrl){
var RegexUrl = /(ftp|http|https):\/\/(\w+:{0,1}\w*@)?(\S+)(:[0-9]+)?(\/|\/([\w#!:.?+=&%@!\-\/]))?/
return RegexUrl.test(strUrl);
}

Or this:

function valid_url($str){
return ( ! preg_match('/^(http|https|ftp):\/\/([A-Z0-9][A-Z0-9_-]*(?:\.[A-Z0-9][A-Z0-9_-]*)+):?(\d+)?\/?/i', $str)) ? FALSE : TRUE;
}


Or this:

$valid = "^(https?|ftp)\:\/\/([a-z0-9+!*(),;?&=\$_.-]+(\:[a-z0-9+!*(),;?&=\$_.-]+)?@)?[a-z0-9+\$_-]+(\.[a-z0-9+\$_-]+)*(\:[0-9]{2,5})?(\/([a-z0-9+\$_-]\.?)+)*\/?(\?[a-z+&\$_.-][a-z0-9;:@/&%=+\$_.-]*)?(#[a-z_.-][a-z0-9+\$_.-]*)?\$";
