Previous Comments: ------------------------------------------------------------------------ [2015-10-22 16:01:36] rasmus@php.net This is likely because 09 and 009 are actually equivalent in a natural sort and the backend sorting algorithm has changed and the order of equivalent elements don't always match the old algorithm. Both outputs are correct there as far as I am concerned. ------------------------------------------------------------------------ [2015-10-22 13:41:54] tronsha at gmx dot de Description: ------------ --- From manual page: http://www.php.net/function.natsort --- I get different results for PHP5 and PHP7 PHP 5 Array ( [5] => 0 [1] => 8 [3] => 009 [0] => 09 [2] => 10 [4] => 011 ) PHP 7 (dev) Array ( [5] => 0 [1] => 8 [0] => 09 [3] => 009 [2] => 10 [4] => 011 ) Test script: --------------- <?php $zeros = array('09', '8', '10', '009', '011', '0'); natsort($zeros); print_r($zeros); Expected result: ---------------- Array ( [5] => 0 [1] => 8 [3] => 009 [0] => 09 [2] => 10 [4] => 011 ) Actual result: -------------- Array ( [5] => 0 [1] => 8 [0] => 09 [3] => 009 [2] => 10 [4] => 011 ) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=70770&edit=1
