Bug description: ArrayAccess doesn't work at all
Description:
------------
I looks like you have never do in-depth testing with ArrayAccess. I you
did you must realize many things are wrong there. It took me less then 5
minutes to kill PHP several times using this naively implemented feature.
Reproduce code:
---------------
class ArrayClass implements ArrayAccess {
public $a = array();
function offsetExists($index) {
return array_key_exists($index, $this->a);
}
function offsetGet($index) {
return $this->a[$index];
}
function offsetSet($index, $newval) {
return $this->a[$index] = $newval;
}
function offsetUnset($index) {
unset($this->a[$index]);
}
}
Expected result:
----------------
It's unclear for me what should I expect.
Definitly not the crashes.
Can anyone explain, what should I expect from e.g.
$obj[1][2][3] = 1; ?
And what should
$a =& $obj[1][2][3];
do?
Actual result:
--------------
$obj[array()] = 1; // crash
$obj[][] = 1; // crash
$x =& $obj[1] // crash
$obj[$obj[1]] = 1; // if offsetGet() returns null, the offsetSet() is
called then
$obj[1]++; // doesn't work at all even if both offsetGet and offsetSet are
modified to return by reference
