Full check.


include_once 'class.w3c.php';
$w3c = new W3C;
$result = $w3c->check("http://example.com");
$valid = ($result["valid"] == true) ? "Valid": "Invalid";
echo "Website {$result[url]} is W3C {$valid} ({$result[result]}), checked as {$result[doctype]} and with {$result[encoding]} encoding.";


Quick check.

include_once 'class.w3c.php';
$w3c = new W3C;

$uris = array(

);

foreach($urls as $url){
$x = $w3c->boolean($url);
echo ($x == true)? "{$url} is Valid!": "{$url} is Invalid!";
echo '<br />';
