Question

我的线程脚本没有看到线程中的另一个类。这是我的代码。

require_once __DIR__.'\vendor\autoload.php';
use Symfony\Component\DomCrawler\Crawler;

$threadCount = 5;
$list = range(0,100);
$list = array_chunk($list, $threadCount);

foreach ($list as $line) {
    $workers = [];
    foreach (range(0,count($line)-1) as $i) {
        $threadName = "Thread #".$i.": ";
        $workers[$i] = new WorkerThreads($threadName,$line[$i]);
        $workers[$i]->start();
    }

    foreach (range(0,count($line)-1) as $i) {
        $workers[$i]->join();
    }
}

class WorkerThreads extends Thread {
    private $threadName;
    private $num;

    public function __construct($threadName,$num) {
        $this->threadName = $threadName;
        $this->num = $num;
    }

    public function run() {
        if ($this->threadName && $this->num) {
            $result = doThis($this->num);
            printf('%sResult for number %s' . "\n", $this->threadName, $this->num);
        }
    }
}

function doThis($num){
    $response = '<html><body><p class="message">Hello World!</p></body></html>';
    $crawler = new Crawler($response);
    $data = $crawler->filter('p')->text();
    return $data;
}

当我运行它时，我收到以下错误消息

Fatal error: Class 'Symfony\Component\SomeComponent\SomeClass' not found

我如何让我的线程看到另一个类？

这是一个有效的解决方案

$autoloader = require __DIR__.'\vendor\autoload.php';
use Symfony\Component\DomCrawler\Crawler;

$threadCount = 1;
$list = range(0,100);
$list = array_chunk($list, $threadCount);


foreach ($list as $line) {
    $workers = [];
    foreach (range(0,count($line)-1) as $i) {
        $threadName = "Thread #".$i.": ";
        $workers[$i] = new WorkerThreads($autoloader,$threadName,$line[$i]);
        $workers[$i]->start();
    }

    foreach (range(0,count($line)-1) as $i) {
        $workers[$i]->join();
    }
}


class WorkerThreads extends Thread {
    private $threadName;
    private $num;

    public function __construct(Composer\Autoload\ClassLoader $loader,$threadName,$num) {
        $this->threadName = $threadName;
        $this->num = $num;
        $this->loader = $loader;
    }

    public function run() {
        $this->loader->register();
        if ($this->threadName && $this->num) {
            $result = doThis($this->num);       
            printf('%sResult for number %s' . "\n", $this->threadName, $this->num);
        }
    }
}



function doThis($num){
    $response = '<html><body><p class="message">Hello World!</p></body></html>';
    $crawler = new Crawler($response);
    $data = $crawler->filter('p')->text();
    return $data;
}

使用线程中的另一个类
