Bug #78992 [NEW]: Inconsistent sorting

From: kfiadeg at gmail dot com Operating system: Linux PHP version: 7.3.13 Package: Arrays related Bug Type: Bug Bug description:Inconsistent sorting Description: ------------ I've encountered inconsistency with sorting string arrays. Sorting arrays that have the same set of elements but in different order produce different results when used with sort() function (without any flags). Test script: --------------- https://pastebin.com/4uKk37by Expected result: ---------------- If arrays have the same set of elements, performing sort() on each of them should give the same order of elements for every array. Actual result: -------------- After sorting array elements keep different order. -- Edit bug report at https://bugs.php.net/bug.php?id=78992&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=78992&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=78992&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=78992&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=78992&r=needscript Try newer version: https://bugs.php.net/fix.php?id=78992&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=78992&r=support Expected behavior: https://bugs.php.net/fix.php?id=78992&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=78992&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=78992&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=78992&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=78992&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=78992&r=dst IIS Stability: https://bugs.php.net/fix.php?id=78992&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=78992&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=78992&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=78992&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=78992&r=mysqlcfg
