(PHP Extension) Async Accept Socket ConnectionDemonstrates how to get the connected client socket after accepting a connection asynchronously.
<?php include("chilkat.php"); // Use "chilkat_9_5_0.php" for versions of Chilkat < 10.0.0 // This example assumes the Chilkat Socket API to have been previously unlocked. // See Socket Unlock Sample for sample code. $listenSocket = new CkSocket(); // Bind to a port and listen. // This example will listen at port 5555 and allows for a backlog // of 25 pending connection requests. $success = $listenSocket->BindAndListen(5555,25); if ($success != true) { print $listenSocket->lastErrorText() . "\n"; exit; } // Start a background task to accept an incoming connection ... $maxWaitMs = 20000; // acceptTask is a CkTask $acceptTask = $listenSocket->AcceptNextConnectionAsync($maxWaitMs); $acceptTask->Run(); // ... // ... // ... // Imagine at this point the task has completed successfully, // and a connection was accepted. Here's how to get the connected socket... $connectedClient = new CkSocket(); $success = $connectedClient->LoadTaskResult($acceptTask); // Here's how it works: The AcceptNextConnection method would normally // return a socket object when called synchronously. When called asynchronously, // it cannot do so because it returns the task object. When the async method // (running in a background thread) completes, the socket object that is the client // connection is contained within the task object. // // This can be generalized for any case where a Chilkat method returns an object. // The async version of that method is such that the object returned in the background // thread is contained within the task object. // To get the result object, we create a new object instance of that type. // In this case, we create a socket object (connectedClient). There is a LoadTaskResult // method in all Chilkat classes that can be a return value of an async method call. // The LoadTaskResult method transfers the returned object from the task to the caller. ?> |
