preg_match URL validating question

[2CODE]

I'm trying to make a URL validating page, This page open an url and then search in it for the a URL that I'll define it

So here's my code :

$check = file_get_contents('http://www.google.com/');

if (preg_match("/http:\/\/www\./test\./com\kok.php/", $check))  

{
echo 'Found';
} else {
echo 'Not found';
}

So after file_get_contents it should match the page if it contain this URL :

http://www.test.com/kok.php

It should echo "Found"

So what's the problem ? The Above code it not working.

well the preg match returns a warning as you regular expression is wrong, and when i visit google.com. i find no reference to your url.

Sure you will not found it at google it's just an example but my real script have this URL but looks like the regular expression is not correct so what's the correct regular expression to identify this URL in the page ?

http://www.test.com/kok.php

"/http:\/\/www\./test\./com\kok.php/"

...should be...

"/http:\/\/www\./test\.com\/kok.php/"

However, I see no reason to use a regular expression for that (and incur its additional overhead) when you could just use strpos() for the same thing, since there is no pattern-matching required.

if (strpos($check, 'http://www.test.com/kok.php') !== false) { // be sure to use !== not !=

(Use [man]stripos/man if you want it to be case-insensitive.)

As always thanks NogDog it's working fine now 🙂
