serialize() casts numeric string keys to integers

["eyal.t" <eyal.t@xxxxxxxx>]

Hi all,

Was wondering whether the fact that serialize() casts numeric string 
keys to integers, is a bug, intended behaviour, or just something that 
is minor enough not to have bothered anyone yet?

<?php

$arr1 = array('1'=>'string key'); // '1' will be casted to 1
$arr2 = array(1=>'integer key');

$arr1_uns = unserialize(serialize($arr1)) ;
$arr2_uns = unserialize(serialize($arr2)) ;

var_dump($arr1_uns, $arr2_uns);


==============================
array(1) {
  [1]=>
  string(10) "string key"
}
array(1) {
  [1]=>
  string(11) "integer key"
}
