Usage
include 'vendor/autoload.php'; use Async\Threads\Thread; $thread = new Thread(); $counter = 0; $t1 = $thread->create_ex(function () { print "Running Thread: 1\n"; return 2; })->then(function (int $output) use (&$counter) { $counter += $output; })->catch(function (\Throwable $e) { print $e->getMessage() . PHP_EOL; }); $t1->join(); // Or $t1->cancel(); print_r($t1->result()); // Or print_r($t1->exception());
Event hooks
When creating Threads processes, you'll get an instance of TWorker
returned.
You can add the following event callback hooks on a Thread
instance.
$thread = new Thread($function, ...$args) $worker = $thread->create($thread_id /* string or int */, function () { }, ...$arguments) ->then(function ($result) { // On success, `$result` is returned by the thread. }) ->catch(function ($exception) { // When an exception is thrown from within a thread, it's caught and passed here. }); $worker = $thread->create_ex(function () { }, ...$arguments) ->then(function ($result) { // On success, `$result` is returned by the thread. }) ->catch(function ($exception) { // When an exception is thrown from within a thread, it's caught and passed here. });
