对象变量在PHP pthread中丢失上下文 [英] Object variable lose context in PHP pthreads

问题描述

我在PHP中使用pthreads时，发现pthreads在其上下文中丢失了对象变量，这是正常现象还是错误，或者我做错了什么?

I was working with pthreads in PHP and noticed that pthreads loses object variables in its context, is this normal or a bug or I'm doing something wrong ?

class Downloader extends Thread {

    private $ch;

    public function __construct($data) {
        $this->ch = curl_init();
    }

    public function __destruct() {
        curl_close($this->ch);
    }

    public function run() {
        // we just lost resource of curl -> [resource(4) of type (Unknown)]
        curl_setopt($this->ch, CURLOPT_URL, $this->url);
    }
}

TL; DR资源在官方上不受支持，再加上pthreads对象如何工作，这将导致您遇到的行为.

TL;DR Resources are officially unsupported, coupled with how pthreads objects work, this leads to the behaviour you are experiencing.
