If a key is the standard representation of an integer, it will be interpreted as such (i.e. "8" will be interpreted as 8, while "08" will be interpreted as "08")." so the keys should be casted to int, or it is a documentation-bug, or "-1" is not a "standard representation of an integer". ------------------------------------------------------------------------ [2003-01-29 00:57:01] sniper@php.net <?php $a = array( '-1' => '-1', '0' => '0', '1' => '1', ); var_dump($a); ?> Output: array(3) { ["-1"]=> string(2) "-1" [0]=> string(1) "0" [1]=> string(1) "1" } (the '0' and '1' indexes are converted to integers..) Not sure if this is actually expected behaviour. :) ------------------------------------------------------------------------ [2003-01-29 00:39:34] nicos@php.net The bug can be that it shouldn't cast positive numbers to string and not that it should cast negative numbers to string. ------------------------------------------------------------------------ [2003-01-29 00:31:41] nicos@php.net 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. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
