PHP pthreads v3下的Volatile简介与使用方法示例_php技巧_

data = 'abc'; var_dump($this->data); //成员设置成标量，是可以再次被改写的 $this->data = 'def'; var_dump($this->data); //这里给data设置为数组时，会自动转换成Volatile对象 $this->data = [1, 2, 3]; var_dump($this->data); //这个时候再给data赋值时，就会报错了 //成员被设置成Threaded对象时(Volatile继承自Threaded)，该成员就不能再次被改写了 $this->data = [4, 5, 6]; var_dump($this->data); //当然，我们可以显式的强制转换，不让Threaded帮我自动转成Volatile对象 $this->result = (array)[1, 2, 3]; //打印出来是数组 var_dump($this->result); $this->result = (array)[4, 5, 6]; //成员赋值成功 var_dump($this->result); } } new Task(); 

data = [ 'a' => 123, 'b' => 456, 'c' => 789, ]; var_dump($this->data); //这里成员数据成功被改写 $this->data = [ 'a' => 'aaa', 'b' => 'bbb', 'c' => 'ccc', ]; var_dump($this->data); //由于Threaded对象实现了ArrayAccess接口，我们可以像访问数组一样，访问Volatile对象 echo $this->data['a'], "\t", $this->data['b'], "\t", $this->data['c'], "\n"; foreach ($this->data as $item) { echo $item, "\n"; } } } new Task();
