范例

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


<?php
$worker = new Worker();

echo "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 {});
}

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

$worker->start();

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

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

$worker->shutdown();

以上例程会输出：

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
