Seems like some operators dont work.f.e. $thread->array[] = 1;  failsa simple test:<?phpclass My extends Thread{    public        $array = array('default val 1', 'default val 2'),        $msg = 'default',        $stop = false;    public function run()    {        while(true)        {            echo $this->msg . PHP_EOL;            if(count($this->array) > 0){                foreach($this->array as $val){                    var_dump($val);                }                $this->array = array();            }            /** cause this thread to wait **/            $this->synchronized(                function($thread){                    if(count($this->array) < 1){                        $thread->wait();                    }                },                $this            );            echo PHP_EOL;            if($this->stop){                break;            }        } // while    }}$my = new My();$my->start();sleep(1); // wait a bit// test 1 - $thread->array[] = 1;$my->synchronized(    function($thread){        $thread->msg = 'test 1';        $thread->array[] = 1;        $thread->notify();    },    $my);sleep(1); // wait a bit// test 2 - array_push($thread->array, 2);$my->synchronized(    function($thread){        $thread->msg = 'test 2';        array_push($thread->array, 2);        $thread->notify();    },    $my);sleep(1); // wait a bit// test 3 - array_push($thread->array, 2);$my->synchronized(    function($thread){        $thread->msg = 'test 3';        $new = array(3);        $thread->array = array_merge($thread->array, $new);        $thread->notify();    },    $my);sleep(1); // wait a bit$my->stop = true;?>out:defaultstring(13) "default val 1"string(13) "default val 2"test 1test 2test 3int(3)so in this case only array_merge() worked.
