    Seems like some operators dont work.
    f.e. $thread->array[] = 1; fails

    a simple test:
    <?php
    class 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:
    default
    string(13) "default val 1"
    string(13) "default val 2"

    test 1

    test 2

    test 3
    int(3)

    so in this case only array_merge() worked.
