(PHP ActiveX) Accept Connection on Socket

Demonstrates how to create a TCP/IP socket, listen on a port, accept an incoming connection, and send a "Hello World" message to the client.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

<?php

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

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Socket')
$listenSocket = new COM("Chilkat.Socket");

// 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 = $listenSocket->BindAndListen(5555,25);
if ($success != 1) {
    print $listenSocket->LastErrorText . "\n";
    exit;
}

// Get the next incoming connection
// Wait a maximum of 20 seconds (20000 millisec)

// connectedSocket is a Chilkat.Socket
$connectedSocket = $listenSocket->AcceptNextConnection(20000);
if ($listenSocket->LastMethodSuccess == 0) {
    print $listenSocket->LastErrorText . "\n";
    exit;
}

// Set maximum timeouts for reading an writing (in millisec)
$connectedSocket->MaxReadIdleMs = 10000;
$connectedSocket->MaxSendIdleMs = 10000;

// Send a "Hello World!" message to the client:
$success = $connectedSocket->SendString('Hello World!');
if ($success != 1) {
    print $connectedSocket->LastErrorText . "\n";

    exit;
}

// Close the connection with the client.
// Wait a max of 20 seconds (20000 millsec)
$success = $connectedSocket->Close(20000);

print 'success!' . "\n";
