Reported By: messju@lammfellpuschen.de
Status: Verified
Bug Type: Arrays related
Operating System: Linux
PHP Version: 4.3.0/5.0.0
New Comment:
The bug can be that it shouldn't cast positive numbers to string and
not that it should cast negative numbers to string.

Verified under PHP 4.3.0 with Zend Engine v1.3.0 and PHP 5.0.0-dev with
Zend Engine v2.0.0-dev.
It looks like '-1' isn't casted to int as it should.

<?php
$a = array(-1=>1,
'-1'=>2,
0=>3,
'0'=>4,
1=>5,
'1'=>6
);
print_r($a);
?>
produces:
Array
(
[-1] => 1
[-1] => 2
[0] => 4
[1] => 6
)
foreach (array_keys($a) as $key) echo $key, ': ', gettype($key), "\n";
produces:
-1: integer
-1: string
0: integer
1: integer
so it seems strings containing negative integers do not get converted
to
integers automagically but positive integers are.
