php多线程自定义类中变量的问题！！！太费解了！！！

[hua_zhixing_]

代码如下，class A中的变量$dat为什么在同一个类里不同函数没效果？如何才能做到对$dat在不同函数里能任意修改？谢谢！

<?php

class A
{
    var $dat;
    public function __construct()
    {
        $this->dat = 0;
        echo "class A construct: \n";
        var_dump($this->dat);
    }
    public function add()
    {
        $this->dat++;
        echo "class A add: \n";
        var_dump($this->dat);
    }
    public function get()
    {
        return $this->dat;
        echo "class A get: \n";
        var_dump($this->dat);
    }

}
class workerThread extends Thread {
    var $data = 0;
    var $datc;
    public function __construct($i){
        $this->i=$i;
        $this->datc = new A();
        echo "thread construct: \n";
        var_dump($this->datc);
    }

    public function opp()
    {
        $this->data ++;
        $this->datc->add();
    }

    public function set()
    {
        $this->data = 8;
    }

    public function show()
    {
        echo "thread show: \n";
        var_dump($this->datc);
        var_dump($this->data);
        var_dump($this->datc->get());
    }

    public function run(){
        $this->opp();
        $this->show();
    }
}

$workers=new workerThread(6);
$workers->set();
$workers->start();

?>

没看懂问题，但我隐隐觉得static这个词会派上用场...

class A extends Stackable
{
    ...

[傲雪星枫]

多线程共享变量吗？

[qq_17167577]

<?php
class A extends Stackable
{
    var $dat;
    public function __construct($dat)
    {
        $this->dat = $dat;
        $this->dat->a = 0;
        echo "class A construct: \n";
        var_dump($this->dat);
    }
    public function add()
    {
        $this->dat->a++;
        echo "class A add: \n";
        var_dump($this->dat);
    }
    public function get()
    {
        echo "class A get: \n";
        var_dump($this->dat);
        return $this->dat;
    }
 
}
class workerThread extends Thread {
    var $data = 0;
    var $datc;
    public function __construct($i, $A){
        $this->i=$i;
        $this->datc = $A;
        echo "thread construct: \n";
        var_dump($this->datc);
    }
 
    public function opp()
    {
        $this->data ++;
        $this->datc->add();
    }
 
    public function set()
    {
        $this->data = 8;
    }
 
    public function show()
    {
        echo "thread show: \n";
        var_dump($this->datc);
        var_dump($this->data);
        var_dump($this->datc->get());
    }
 
    public function run(){
        $this->opp();
        $this->show();
    }
}

// 1、只有Stackable对象才能在线程中传递 2、并且线程间被传递的对象一定要在全局有引用
$dat = new Stackable();
$A = new A($dat);
$workers=new workerThread(6, $A);
$workers->set();
$workers->start();

static 或者 &传引用 你们怎么看

引用 2 楼 qq_17167577 的回复:

class A extends Stackable
{
    ...

如果类A中的变量是数组的话，还是存在同样的问题，构造函数里设的什么值就什么值，其它函数不能修改，为什么？

[xuzuning]

按单例模式设计 A 类
