如何使用扩展名pthreads将参数从我的主线程传递到PHP中的新线程？

与PHP中的How can I pass a parameter to a Java Thread?类似。

Answer 1

就像使用PHP [或任何语言]中的任何其他对象一样，您应该将参数传递给构造函数以设置成员。

class My extends Thread {

    public function __construct($greet) {
        $this->greet = $greet;
    }

    public function run() {
        printf(
            "Hello %s\n", $this->greet);
    }
}

$my = new My("World");
$my->start();
$my->join();

对于你刚刚传递的标量和简单数据，不需要采取任何特殊操作，但是如果你打算在多个线程中操作一个对象，那么对象的类应该来自pthreads：

class Greeting extends Threaded {

    public function __construct($greet) {
        $this->greet = $greet;
    }

    public function fetch() {
        return $this->greet;
    }

    protected $greet;
}

class My extends Thread {

    public function __construct(Greeting $greet) {
        $this->greet = $greet;
    }

    public function run() {
        printf(
            "Hello %s\n", $this->greet->fetch());
    }
}

$greeting = new Greeting("World");
$my = new My($greeting);
$my->start();
$my->join();

Answer 2

从这段代码开始：

http://www.php.net/manual/en/thread.start.php

<?php
class My extends Thread {
    public $data = "";
    public function run() {
        /** ... **/
    }
}
$my = new My();
$my->data = "something"; // Pass something to the Thread before you actually start it.
var_dump($my->start());
?>
