PHP+JAVASCRIPT url regex with GET params

Question

I am kind of banging my head to the wall here. I am trying all sorts of URLs, and regex's some I made up, some I just found on the web.

It seems like PHP and Javascript don't interpret the strings the same. I need a string for a (GET params possibly) PHP and JAVASCRIPT that would work the same on the client and server side. As it is now, the client is ok, while the server isn't or the other way around.

Can anyone send such a string with it's equivalence php/javascript ?

Thanks so much in advance !

By the way, I use http://regexpal.com/ I think it is a great tool !

Trying to validate a url field on the client side, and upon for submission, to validate it on my php server — Ted

I think I got something... I can't really post another answer, but I will write it here, sorry... $regex = '/^((https?|ftp)?\:\/\/)?([a-z0-9+!*(),;?&=\$_.-]+(\:[a-z0-9+!*(),;?&=\$_.-]+)?@)?([a-z0-9-.]*)\.([a-z]{2,3})(\:[0-9]{2,5})?(\/([a-z0-9+\$_-]\.?)+)*\/?(\?[a-z+&\$_.-][a-z0-9;:@&%=+\/\$_.-]*)?(#[a-z_.-][a-z0-9+\$_.-]*)?/'; if (preg_match($regex,$url)) { //$err_validation[]= 'url ok'; return true; } — Ted

Do a search for "validate URL" - this question gets asked a lot. — ridgerunner

Thanks, it's very weird but when I set my $regex='that php long string', I get a weird error saying: Notice: Undefined variable: iuS in C:\xampp\htdocs\test.php on line 657 ......... What's weird about it is that it doesn't complain on the preg_match, but on the variable which I haven't even defined (it is $regex, not a part of the string), am I missing a point here ?

You used the long string in the comments? Try using

'/^(?:(?:https?|ftp):\/\/)(?:\S+(?::\S*)?@|\d{1,3}(?:\.\d{1,3}){3}|(?:(?:[a-z\d\x{00a1}-\x{ffff}]+-?)*[a-z\d\x{00a1}-\x{ffff}]+)(?:\.(?:[a-z\d\x{00a1}-\x{ffff}]+-?)*[a-z\d\x{00a1}-\x{ffff}]+)*(?:\.[a-z\x{00a1}-\x{ffff}]{2,6}))(?::\d+)?(?:[^\s]*)?$/iu'
