var_export array bug when its keys are negative numbers?

Question

PHP

<?php
$data = array('moder'=> array(
    -2 => array(
        2=>1,
        1=>1,
        0=>1,
        -1=>-1,
        -2=>-2,
    )
));
print '<pre>';
print '<h1>print_r</h1>';
print_r($data);

print '<h1>var_dump</h1>';
var_dump($data);
print '</pre>';

print '<h1>var_export (BAD keys!!!)</h1>';
$code = '<?php
return '.var_export($data, true);
print highlight_string($code);

print '<h1>serialize</h1>';
print serialize($data);

print '<h1>some script</h1>';
highlight_file(__FILE__);

Result (only different parts here):

How to achieve the same expected results regardless of the platform?

Answer 1

The bug was in 5.2.x, closed in 5.3.4. bugs.php.net/bug.php?id=52534

Answer 2

Apparently, the bug was in 5.3.2, and in 5.3.10 it has already been fixed.
System x86 or x64?

Answer 3

Try to specify the keys not as -1 , but as '-1' - as strings.
