(PHP Extension) TCP/IP Socket Connect to Remote Host:PortDemonstrates how to create a TCP/IP socket, connect to a remote host:port, and receive a "Hello World!" message.
<?php // The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number. // For example, if using Chilkat v9.5.0.48, then include as shown here: include("chilkat_9_5_0.php"); // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. $socket = new CkSocket(); // 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 = false; $maxWaitMillisec = 20000; $success = $socket->Connect('localhost',5555,$ssl,$maxWaitMillisec); if ($success != true) { print $socket->lastErrorText() . "\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 = $socket->receiveString(); if ($socket->get_LastMethodSuccess() != true) { print $socket->lastErrorText() . "\n"; exit; } // Close the connection with the server // Wait a max of 20 seconds (20000 millsec) $success = $socket->Close(20000); print $receivedMsg . "\n"; ?> |
