I'm having a problem using a dynamic array to filter the data I want to retrieve from my MongoDB.

I have an array which is stored in $this->x and when I print_r($this->x) the result is the same as before:

Array
(
    [0] => 1
    [1] => 2
    [2] => 54
    [3] => 55
)

but the query won't return any values. Query -> $c = $col->find(array('Aliens.Id' => array('$in' => $this->x)));

The strange thing is that when I do the query like this -> $c = $col->find(array('Aliens.Id' => array('$in' => array(1,2,54,55))); it returns values!!

If I print_r(array(1,2,54,55)) the output is:

Array
(
    [0] => 1
    [1] => 2
    [2] => 54
    [3] => 55
)

Note: $this->x is also an array.
