สอบถามการเช็ค Connect Uptime กับ Database server และ Dns Server ครับ

$fp1 = fsockopen("localhost", 8889, $errno, $errstr, 30);
if (!$fp1) {
    echo "$errstr ($errno)<br />\n";
} else {
    $objConnect = mysql_connect("localhost","root","root");
    if($objConnect) {
        echo "Database Connected.<br />";
    }
    else {
        echo "Database Connect Failed.<br />";
    }
    mysql_close($objConnect);

    fclose($fp1);
} //Core code check Database Server

$fp2 = fsockopen("8.8.8.8", 53, $errno, $errstr, 30);
if (!$fp2) {
    echo "$errstr ($errno)<br />\n";
} else {
    $ip = gethostbyname('www.facebook.com');
    echo $ip;
    }
    
    fclose($fp2);
//Core code check DNS Server
