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 } }
