Ping is a simple PHP class for pinging hosts.
There are a ton of different methods of pinging a server using PHP, and I've found most to be poorly documented or downright dangerous in their implementation.
Therefore, I've created this simple class, which incorporates the three most popular ping methods (
exec() with the system's
socket_create()). Each method has it's benefits and drawbacks, and may work better or worse on a particular system.
