<?php

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

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

//  To use a SOCKS4 or SOCKS5 proxy, simply set the following
//  properties prior to calling Connect.  The connection may be SSL/TLS or
//  non-secure - both will work with a SOCKS proxy.
//  The SOCKS hostname may be a domain name or
//  IP address:
$socket->SocksHostname = 'www.mysocksproxyserver.com';
$socket->SocksPort = 1080;
$socket->SocksUsername = 'myProxyLogin';
$socket->SocksPassword = 'myProxyPassword';
//  Set the SOCKS version to 4 or 5 based on the version
//  of the SOCKS proxy server:
$socket->SocksVersion = 5;
//  Note: SOCKS4 servers only support usernames without passwords.
//  SOCKS5 servers support full login/password authentication.

//  Connect 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 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);

print $receivedMsg . "\n";
