$socket = new COM("Chilkat.Socket");

$success = $socket->UnlockComponent('Anything for 30-day trial');
if ($success != 1) {
    print $socket->lastErrorText() . "\n";
    exit;
}

//  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->HttpProxyHostname = 'www.my-http-proxy.com';
$socket->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 = 0;
$maxWaitMillisec = 20000;
$success = $socket->Connect($hostname,5555,$ssl,$maxWaitMillisec);
if ($success != 1) {
    print $socket->lastErrorText() . "\n";
    exit;
}

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

//  The ficticious server (in this example) is going to send a "Hello World!"
//  message.  Read it:

$receivedMsg = $socket->receiveString();
if (is_null($receivedMsg)) {
    print $socket->lastErrorText() . "\n";
    exit;
}

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