Exemple #1 A basic example of Worker::collect()

= new Worker();

"There are currently {$worker->collect()} tasks on the stack to be collected\n";

for (
$i 0$i 15; ++$i) {
$worker->stack(new class extends Threaded {});

"There are {$worker->collect()} tasks remaining on the stack to be collected\n";


while (
$worker->collect()); // blocks until all tasks have finished executing

echo "There are now {$worker->collect()} tasks on the stack to be collected\n";

There are currently 0 tasks on the stack to be collected
There are 15 tasks remaining on the stack to be collected
There are now 0 tasks on the stack to be collected
