Bug #74042 [NEW]: SORT_NATURAL does not work or pass tests

From: ejrx7753 at gmail dot com Operating system: OS X Sierra, Ubuntu 16.04 PHP version: 7.0.15 Package: PDO Core Bug Type: Bug Bug description:SORT_NATURAL does not work or pass tests Description: ------------ A section of "ext/standard/tests/array/sort_basic.phpt" with case insensitive natural sort does not give the expected result. 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 bug report at https://bugs.php.net/bug.php?id=74042&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=74042&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=74042&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=74042&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=74042&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=74042&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=74042&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=74042&r=needscript Try newer version: https://bugs.php.net/fix.php?id=74042&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=74042&r=support Expected behavior: https://bugs.php.net/fix.php?id=74042&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=74042&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=74042&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=74042&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=74042&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=74042&r=dst IIS Stability: https://bugs.php.net/fix.php?id=74042&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=74042&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=74042&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=74042&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=74042&r=mysqlcfg
