reg expression for URL

[TheOne17]

I have been using this function to validate an URL from field

 

function checkURL($url)

{

return eregi("^(http|https|ftp)\://[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(:[a-zA-Z0-9]*)?/?([a-zA-Z0-9\-\._\?\,\'/\\\+&%\$#\=~])*[^\.\,\)\(\s]$", $url);

}

 

The only problem is that is won't accept URL's with a hyphen in

e.g.

www.northlincs.gov.uk/20-21

 

Does anyone know how to modify this to work with hyphens or have a good reg exp for URL's that will work with hyphens

 

Thanks

<?php
$url="http://www.google.co.uk";
if(eregi("^(http://|https://|ftp://|
http://www.)+[a-z0-9\_\-]{1,25}\.+
([a-z0-9\_\-]{1,3}|.+[a-z0-9\_\-]{1,3}\.
+[a-z0-9\_\-]{1,3})$", $url)
){
echo" your url is: $url";
}else{
echo"sorry wrong url: $url format";
}
?>

 

This will do what ever but only for the index of the domain not what your trying to do if

you want to your need to alter the code and add another or | ok.

You can find more methods by searching for "http ftp" in the Regular Expressions board.
