Get the LastErrorText for an Asynchronous Method Call

Demonstrates how to get the LastErrorText information for a Chilkat method called asynchronously. PHP ActiveX

<?php

$success = 0;

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

$socket = new COM("Chilkat.Socket");

// The Async call simply creates the task.  The "Connect" method has not yet been called.
$maxWaitMs = 5000;
// Let's intentionally cause this connect to fail by giving it an invalid domain..
// task is a Chilkat.Task
$task = $socket->ConnectAsync('amazonbladflakjsdflksadjf.com',443,1,$maxWaitMs);
if ($socket->LastMethodSuccess == 0) {
    print $socket->LastErrorText . "\n";
    exit;
}

// Start the background thread to run the task.
$success = $task->Run();
if (!$success) {
    print $task->LastErrorText . "\n";

    exit;
}

// The application is now free to do anything else

// For this example, we'll simply sleep and periodically
// check to see if the Socket Connect if finished.
while ($task->Finished != 1) {
    // Sleep 1 ms.
    $task->SleepMs(1);
}

// If the task completed, it means the method (in this case the Connect method) was called and returned success or failure.
if ($task->StatusInt != 7) {
    print 'Task did not complete.' . "\n";
    print 'task status: ' . $task->Status . "\n";

    exit;
}

// Get the success/failure of the Connect
// (This is the return value of the Connect method had it been called synchronously)
$success = $task->GetResultBool();
if ($success == 0) {
    // Get the LastErrorText for the Connect method call.
    // Had we called Connect synchronously, we would've simply accessed the socket object's LastErrorText property.
    // Instead, we get the task object's ResultErrorText.
    print $task->ResultErrorText . "\n";
}
else {
    print 'Connect succeeded.' . "\n";
