$url = $endpoint . urlencode($yqlforge) . '&diagnostics=false&format=xml';
function get($url) {
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,2);
$data = curl_exec($ch);
$data = preg_replace('/<\?.*?>/','',$data);
$data = preg_replace('/<\!--.*-->/','',$data);
$data = preg_replace('/.*?<results>/','',$data);
$data = preg_replace('/<\/results>.*/','',$data);
$data = preg_replace('/ href="/',' href="http://mootools.net',$data);
$data = preg_replace('/ src="/',' src="http://mootools.net',$data);
curl_close($ch);
if(empty($data)) {return 'Server Timeout. Try again later!';}
