use chilkat();

$socket = new chilkat::CkSocket();

$success = $socket->UnlockComponent("Anything for 30-day trial");

}

#  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->put_SocksHostname("www.mysocksproxyserver.com");
$socket->put_SocksPort(1080);
$socket->put_SocksUsername("myProxyLogin");
$socket->put_SocksPassword("myProxyPassword");
#  Set the SOCKS version to 4 or 5 based on the version
#  of the SOCKS proxy server:
$socket->put_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->put_MaxReadIdleMs(10000);
$socket->put_MaxSendIdleMs(10000);

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

$receivedMsg = $socket->receiveString();
if ($receivedMsg eq null ) {
    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";
