Try this:
function url_exist($url) {
$url_parts = parse_url($url);
$fp = fsockopen($url_parts["host"], 80);
if (!$fp) return false;
$path = $url_parts["path")?$url_parts["path"]:"/";
fwrite($fp, "GET $path HTTP/1.0\r\n\r\n");
$response = fgets($fp, 500);
preg_match("/^HTTP\/\d\.\d[ \t]+(\d+)[ \t]*([^\r]*)/", $response, $matches);
switch ($matches[1]) {
case 404: // HTTP error not found
return false;
case 200: // HTTP OK
return true;
default:
return false; // other responses probably counts false
}
}
