url validation

[legal-medium]

Does anyone have a URL validation function I could use

Thanks

What of the url do you want to validate? The format (i.e. make sure it's a valid URL)? Or if the url exists?

I want to check the format of the string

something similar to this function :

function valid_email ($email) {
if (eregi("^{0-9a-z@0-9a-z\.[a-z]{2,3}$",} $email, $check)) {
return TRUE;}
return FALSE;}

Thanks in advance

Well, URL validation is more complicated than e-mail validation, because there are optional things that could go into a URL, like authentication stuff, port number, etc, so it's harder to validate with just one regular expression (trust me, I just tried and it ended up huge).

What I'd suggest is to use parse_url() to get each part of the URL, and then verify each fragment individually.
