<?php include("chilkat.php"); $success = false; // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. $socket = new CkSocket(); $ssl = true; $maxWaitMillisec = 20000; // The SSL server hostname may be an IP address, a domain name, // or "localhost". $sslServerHost = 'www.paypal.com'; $sslServerPort = 443; // Connect to the SSL server: $success = $socket->Connect($sslServerHost,$sslServerPort,$ssl,$maxWaitMillisec); if ($success == false) { print $socket->lastErrorText() .

"\n"; } // Close the connection with the server // Wait a max of 20 seconds (20000 millsec) $success = $socket->Close(20000); ?> |
