(PHP ActiveX) Async Methods Returning an ObjectDemonstrates how to call an asynchronous method that returns an object. This example reads email from a POP3 server using the Async versions of the Chilkat methods.
<?php // All Chilkat classes can be unlocked at once at the beginning of a program // by calling UnlockBundle. It requires a Bundle unlock code. // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Global') $chilkatGlob = new COM("Chilkat.Global"); $success = $chilkatGlob->UnlockBundle('Anything for 30-day trial.'); if ($success != 1) { print $chilkatGlob->LastErrorText .

This object is // loaded by calling LoadTaskResult. $success = $email->LoadTaskResult($task); if (!$success) { print $email->LastErrorText . "\n"; exit; } else { print $email->From .
