Validating Web Pages

Thought I would share this bit of code as some people might find it useful. Ever since I started working to make sure my pages were compatible, I have come up with a number of things to help me to accomplish this. Now, every page on this site should be fully xHTML compliant and I have setup a number of backend protections to stop most things from causing the sites to stop validating. One thing I wrote was a simple PHP function that can be used in any script that gives some feedback as to if a website is valid or not.

function validate_page($url) { $url = urlencode($url); $site = "http://validator.w3.org/check?uri=$url"; $data = implode("", file($site)); $result = preg_match_all ("/\<h2 class\=\"valid\"\>/", $data, $matches); return $result; }

Usage:

$page = "http://www.cbulock.com/"; $result = validate_page($page);

Basically, give the function a URL, it will send back either a 1 or 0 depending on if it's a valid page or not. If this is something useful, go ahead and use it, it's free to use as you please.
