How can I ping a server IP and check if it's online or not? I want to have a web page that shows the status of a Minecraft server to show whether it is online or not.
Open a socket on the port Minecraft is listening on
[php]
<?php
function serverAlive($serverLocation, $serverPort){
error_reporting(0);
return !(!fsockopen($serverLocation, $serverPort));
}
echo "server is " . ((serverAlive($_GET['s'], $_GET['p']))? "up" : "down") ;
?>
// Provide server address with ?s= and port with &p=.
[/php]

I'm a little puzzled by the significance of the double negate there :\

fsockopen() returns a file pointer when the connection is opened properly. Rather than returning that, I simply check if it is valid based upon (!fsockopen()) and then reverse the negative with another !(). That makes it return a boolean vs a file pointer.

Couldn't you just stick in a '!== FALSE'? Would be more readable IMO.
Awesome code snippet regardless.
It's more fun my way. :wink:

It's also a few less bytes.

This is perfect, thanks.
I made a configurable python script that you're free to use for this :v:
It returns an image instead of a string, though. There's a few guides on minecraftforum.net, but here's an example since that tutorial still uses the link to the php one.
Checking on 127.0.0.1 on port 9001: [img]http://res.public-craft.com/hb.pyc?ip=127.0.0.1&port=9001&on=INSERTURLHERE&off=INSERTURLHERE[/img]
