PHP script to check server status online/offline

i wrote a simple php script to check whether the website or Ip address is online or offline. All you have to do is specify a website url or ip address and the script will return with ONLINE or OFFLINE. I used php fsockopen() to accomplish this.

/* Usage:
$status =  GetServerStatus('http://domain.com',80)
or
$status =  GetServerStatus('IPAddress',80)
*/

<?php
function GetServerStatus($site, $port)
{
$status = array("OFFLINE", "ONLINE");
$fp = @fsockopen($site, $port, $errno, $errstr, 2);
if (!$fp) {
    return $status[0];
} else
  { return $status[1];}
}
?>

If you want to ping a server to check connectivity, you can use php ping scripts.

    Good script. I would just return true or false though, this way you can use the result however you want (and it’s easier to do so).

    Keep in mind, not all web hosts allow fSock to connect directly to their server resulting in OFFLINE even when it is actually ONLINE. But for everyone else, it works well.

      If you simply want people to check the status of, let’s say your website, you would just have to copy this function into your php code, and when you want to use it you just have to type “echo GetServerStatus();” and it will echo out ONLINE or OFFLINE :)

    It would be better to check for status code and return it as well.
