Answer 1

No, you added the values later than the __construct() fired.

class test{
    var $var_test = array();
    function __construct($vars)
    {
        $this->var_test = $vars;
        var_dump($this);
    }
}
new test(array('one','two'));

will working.

Answer 2

No, the output of this is not null, the output is this:

object(test)#1 (1) {
  ["var_test"]=>
  array(0) {
  }
}

which means that var_test is an empty array.

The constructor (__construct function) is called at line one, and on line two you assign things to your array. Therefore, when constructor runs, the array has not been populated yet, and is therefore empty.
