It should be noted that objects can be compared using only their accessible properties using
get_object_vars().
Per example, in this class:
class X {
public $a;
private $b;
public function __construct($a, $b) {
$this->a = $a;
$this->b = $b;
}
}
You can ignore the private properties when comparing them outside the class scope, like this:
$a = new X(1, 1);
$b = new X(1, 0);
var_dump(get_object_vars($a) == get_object_vars($b));
Just remember that get_object_vars() return different properties depending on the scope where you
call it, so calling the above within one of X member will compare the private properties.
