The problem is that it makes it difficult to use recursive objects; consider this code:
class A { var $b; function A() { $this->b =& new B($this); } } class B { var $a; function B(&$a) { $this->a =& $a; } } $one =& new A; $two =& new A; $three =& $one; if ($one == $three) { echo "this works with the hashtable == test added"; } if ($one == $two) { echo "this causes a fatal error without the E_WARNING patch"; } I suppose that what I'm really after is an "is_same_object" test, rather than a is_equal_object or is_identical_object. Any chance that we could have something like this in the 4.3 release? Essentially, the code just needs to compare the object properties hashtables to decide if the objects are the same and return a boolean if that is the case. ZEND_FUNCTION(is_same_object) { zval **obj1, **obj2; if (ZEND_NUM_ARGS() != 2 || zend_get_parameters_ex(2, &obj1, &obj2) == FAILURE) { ZEND_WRONG_PARAM_COUNT(); } if (Z_TYPE_PP(obj1) != IS_OBJECT || Z_TYPE_PP(obj2) != IS_OBJECT) { RETURN_FALSE; } RETURN_BOOL(Z_OBJCE_PP(obj1) == Z_OBJCE_PP(obj2) && Z_OBJPROP_PP(obj1) == Z_OBJPROP_PP(obj2)); } --Wez.
