// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

$listenSocket = new CkSocket();

// Bind to a port and listen for incoming connections:
// This example will listen at port 5555 and allows for a backlog
// of 25 pending connection requests.
$success = $listenSocket->BindAndListen(5555,25);

// Wait a maximum of 20 seconds (20000 millisec)

// connectedSocket is a CkSocket
