Edit report at https://bugs.php.net/bug.php?id=74042&edit=1 ID: 74042 Comment by: ejrx7753 at gmail dot com Reported by: ejrx7753 at gmail dot com Summary: SORT_NATURAL does not work or pass tests Status: Open Type: Bug Package: Arrays related Operating System: OS X Sierra, Ubuntu 16.04 PHP Version: 7.0.15 Block user comment: N Private report: N New Comment: Correction - does not properly test the "case sensitive" call. Just a side note not central to the report.

Tested on OS X Sierra PHP 7.0.13, PHP 7.1.0, and "PHP 7.0.13-0ubuntu0.16.04.1" The test expects [6]=> string(7) "Orange3" [7]=> string(8) "orange20" But it gives string(8) "orange20" [7]=> string(7) "Orange3" Obivously expecting "3" before "20" in nat sort. Note also that the sort_basic does not properly test the insensitive case (as there are no exeptional elements with case considered) so that was not tested and assumed also to be not working. Test script: --------------- <?php // associative array containing unsorted string values $unsorted_strings = array( "l" => "lemon", "o" => "orange", "O" => "Orange", "O1" => "Orange1", "o2" => "orange2", "O3" => "Orange3", "o20" => "orange20", "b" => "banana", ); echo "\n-- Testing sort() by supplying string array (natural, case insensitive), 'flag' = SORT_NATURAL|SORT_FLAG_CASE --\n"; $temp_array = $unsorted_strings; sort($temp_array, SORT_NATURAL|SORT_FLAG_CASE); var_dump( $temp_array); Expected result: ---------------- [6]=> string(7) "Orange3" [7]=> string(8) "orange20" Actual result: -------------- string(8) "orange20" [7]=> string(7) "Orange3" ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=74042&edit=1
