New Comment:
When an array is of mixed type or doesn't contain sequential keys it has
to be
treated as a hash and not as an integer
json_encode() turns the integer keys into strings which it has to do to
be valid
json.
On json_decode() it see's string keys instead of numeric since this is a
hash
not an array.
There is nothing unexpected happening here.

there is an easier way to build such an array.
$obj = new stdClass;
$obj->{'123'} = 1;
$arr = (array) $obj;
var_dump($obj);

Description:
------------
php treat numeric string key as interge,
bug sometimes there is some exception.
for example:
while change a std object to array, numeric string key doesn't cast to
number
Test script:
---------------
<?php
$data = array(
123 => 'laruence',
"03"=> 'baidu',
);
$value = json_encode($data);
$obj = json_decode($value);
$arr = (array)$obj;
var_dump($arr);
?>
Expected result:
----------------
array(2) {
[123]=>
string(8) "laruence"
["03"]=>
string(5) "baidu"
}
Actual result:
--------------
array(2) {
["123"]=>
string(8) "laruence"
["03"]=>
string(5) "baidu"
}
