#45877 [NEW]: Array key '2147483647' left as string

Bug description:  Array key '2147483647' left as string

Description:
------------
I believe '2147483647' (= 2^31 - 1) should be the standard representation
of a valid integer, but using the string form as an array key stores the
key as a string, not an integer.  The integer key 2147483647 can be used
separately to refer to a different value, and both are stored.  See repro
code below:

Note: this bug is admittedly duplicate of bug #13407, but the bug still
exists, and I fail to understand why the original bug was marked bogus. 
Thanks for your time.

Reproduce code:
---------------
$v = array('2147483647' => 'b', '2147483646' => 'c', 2147483647 => 'd');
var_dump($v);

Expected result:
----------------
array(2) {
  [2147483647]=>
  string(1) "d"
  [2147483646]=>
  string(1) "c"
}

Actual result:
--------------
array(3) {
  ["2147483647"]=>
  string(1) "b"
  [2147483646]=>
  string(1) "c"
  [2147483647]=>
  string(1) "d"
}
