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.
