use chilkat();

$socket = new chilkat::CkSocket();

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

#  Connect to port 5555 of localhost.
#  The string "localhost" is for testing on a single computer.
#  It would typically be replaced with an IP hostname, such
#  as "www.chilkatsoft.com".
$ssl = 0;
$maxWaitMillisec = 20000;
$success = $socket->Connect("localhost",5555,$ssl,$maxWaitMillisec);
if ($success != 1) {
    print $socket->lastErrorText() . "\r\n";
    exit;
}

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

#  Pretend, for the sake of the example, that the
#  ficticious server is going to send a "Hello World!"
#  after accepting the connection.
#  Note: Technically, the ReceiveString may not receive the
#  complete string, although it's highly probable given the short
#  length of the "Hello World!" message.
#  See this Chilkat blog post for more information:
#  http://www.cknotes.com/?p=302

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

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

print $receivedMsg . "\n";
