[PHP-BUG] Bug #75328 [NEW]: Unable to typecast numeric array key to string

From:             langebroek at gmail dot com
Operating system: Any
PHP version:      Irrelevant
Package:          PHP Language Specification
Bug Type:         Bug
Bug description:Unable to typecast numeric array key to string

Description:
------------
Rather self explanatory; it seems impossible to have a numeric string as
an array key. For the project I'm working on this is almost a necessity.

Test script:
---------------
$buf=array((string)1=>'x',"2"=>'y','3'=>'z');
#var_dump($buf);//all int
var_dump(array_keys($buf));//clarify all int

Expected result:
----------------
In at least one case I'd expect to see a string in the array key, or
have an alternative method to achieve such. In some cases it is unwise
to typecast at a later time.

Actual result:
--------------
array(3) {
  [0]=>
  int(1)
  [1]=>
  int(2)
  [2]=>
  int(3)
}
