Detecting if a server is online/offline

[CodemasterMM]

I'm wondering if there is a way you can use PHP to check if a file is on the server, and if it isn't, it displays another image (or text), such as xDCC Spy does with their servers.

Thanks for your help 😃

Just use an else statemnet with opening a file and put print "<img>"; in the else.
