我已经尝试过这个 Joe 回答/sf/answers/2253097241/ 中的示例,它运行良好,但是当我尝试稍微编辑此代码时:
$pool = new Pool(4);
while (@$i++<10) {
$pool->submit(new class($i) extends Collectable {
public function __construct($id) {
$this->id = $id;
}
public function run() {
printf(
"Hello World from %d\n", $this->id);
$this->html = file_get_contents('http://google.fr?q=' . $this->query);
$this->setGarbage();
}
public $id;
public $html;
});
}
while ($pool->collect(function(Collectable $work){
printf(
"Collecting %d\n", $work->id);
var_dump($work->html);
return $work->isGarbage();
})) continue;
$pool->shutdown();

“Hello world”的计数与“Collecting”的计数不同。文档已过时。这个问题怎么办?
