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.
