关于PHP多线程pthreads调用静态类的疑问

Question

<?php
class b extends Thread {
    public $func = null;

    public function run() {
        $c = new c();

        var_dump($c->listA);
        var_dump(c::$listB);
        var_dump(c::$hello);
    }
}

class c {
    public $listA = ['a', 'b', 'c'];
    public static $listB = ['a', 'b', 'c'];
    public static $hello = 'hello world!';
}

$b = new b();
$b->start();

输出值为：

array(3) {
  [0]=>
  string(1) "a"
  [1]=>
  string(1) "b"
  [2]=>
  string(1) "c"
}
NULL
string(12) "hello world!"

WTF?
大神们，$listB 的数组去哪了？

我使用你的程序，得到的是正确的结果：

root@f4c57ecbbc9f:/data/php/pthreads# cat test.php
<?php
class b extends Thread {
    public $func = null;

    public function run() {
        $c = new c();

        var_dump($c->listA);
        var_dump(c::$listB);
        var_dump(c::$hello);
    }
}

class c {
    public $listA = ['a', 'b', 'c'];
    public static $listB = ['a', 'b', 'c'];
    public static $hello = 'hello world!';
}
$b = new b();
$b->start();

root@f4c57ecbbc9f:/data/php/pthreads# php test.php 
array(3) {
  [0]=>
  string(1) "a"
  [1]=>
  string(1) "b"
  [2]=>
  string(1) "c"
}
array(3) {
  [0]=>
  string(1) "a"
  [1]=>
  string(1) "b"
  [2]=>
  string(1) "c"
}
string(12) "hello world!"

环境如下:
