// 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.

$socket = new CkSocket();

// To connect through an HTTP proxy, set the HttpProxyHostname
// and HttpProxyPort properties to the hostname (or IP address)
// and port of the HTTP proxy.  Typical port numbers used by
// HTTP proxy servers are 3128 and 8080.
$socket->put_HttpProxyHostname('www.my-http-proxy.com');
$socket->put_HttpProxyPort(3128);

// Important:  Your HTTP proxy server must allow non-HTTP
// traffic to pass.  Otherwise this does not work.

// Connect (via the HTTP proxy) to port 5555 of 192.168.1.108.
// hostname may be a domain name or IP address.
$hostname = '192.168.1.108';
$ssl = false;
$maxWaitMillisec = 20000;
$success = $socket->Connect($hostname,5555,$ssl,$maxWaitMillisec);
if ($success != true) {
    print $socket->lastErrorText() . "\n";
    exit;
}

// Set maximum timeouts for reading an writing (in millisec)
$socket->put_MaxReadIdleMs(10000);
$socket->put_MaxSendIdleMs(10000);

// The ficticious server (in this example) is going to send a "Hello World!" 
// message.  Read it:
$receivedMsg = $socket->receiveString();
if ($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";
