<?php

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

$socket = new CkSocket();

$ssl = true;
$maxWaitMillisec = 20000;

// The SSL server hostname may be an IP address, a domain name,
// or "localhost".  You'll need to change this:

$sslServerHost = '123.123.88.88';
$sslServerPort = 8123;

// Connect to the SSL server:
$success = $socket->Connect($sslServerHost,$sslServerPort,$ssl,$maxWaitMillisec);
if ($success != true) {
    print $socket->lastErrorText() . "\n";
    exit;
}

// Set maximum timeouts for reading an writing (in millisec)
$socket->put_MaxReadIdleMs(20000);
$socket->put_MaxSendIdleMs(20000);

// Send a "Hello Server! -EOM-" message:
$success = $socket->SendString('Hello Server! -EOM-');
if ($success != true) {
    print $socket->lastErrorText() . "\n";
    exit;
}

// The server (in this example) is going to send a "Hello Client! -EOM-" 
// message.  Read it:
$receivedMsg = $socket->receiveUntilMatch('-EOM-');
if ($socket->get_LastMethodSuccess() != true) {
    print $socket->lastErrorText() . "\n";
    exit;
}

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

print $receivedMsg . "\n";
