ID: 49698 Updated by: rasmus@php.net Reported By: sander dot vink at procurios dot nl -Status: Open +Status: Closed Bug Type: Strings related Operating System: Linux PHP Version: 5.2.11 New Comment: I have fixed this regression, although if you have an integer prefix on your strings, I am not sure why you are using strnatcasecmp on those.

Are you sure it is fixed in PHP 5.3-HEAD, and if so, when will it be available as either snapshot or release? ------------------------------------------------------------------------ [2009-09-28 11:22:53] sjoerd@php.net This seems to be solved already in PHP 5.3-HEAD. ------------------------------------------------------------------------ [2009-09-28 07:56:04] sander dot vink at procurios dot nl Description: ------------ We use the strnatcasecmp()-function to get a "natural order" in our lists of items. Up until PHP 5.2.9 it worked like a charm, but since we upgraded to PHP 5.2.11 the order seems to have been changed. The natural order is used in our case to support the sorting of items that have been prefixed with numbers (0, 1, 2, etc). This is exactly where the problem arises: 0 should be "sorted" before 1, but this is no longer the case. This problem also occurs in the latest snapshot of PHP 5.3 Reproduce code: --------------- <?php $string1 = '0 Foo'; $string2 = '1 Bar'; var_dump(strnatcasecmp($string1, $string2)); Expected result: ---------------- int(-1) Actual result: -------------- int(1) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=49698&edit=1
