Doc #76971 [NEW]: Changed array append behaviour of array_unique

From: bjoern dot fischer at dezem dot de Operating system: Linux PHP version: 7.2.10 Package: Arrays related Bug Type: Documentation Problem Bug description:Changed array append behaviour of array_unique Description: ------------ --- From manual page: http://www.php.net/function.array-unique --- Beginning with PHP-7.2 appending an element to an array, after calling array_unique, changed behaviour. Before, the internal array-index-pointer was unchanged after calling array_unique, now with PHP 7.2 the array-index-pointer is set to the last remaining array element. This should be documented. This can be tested here: https://3v4l.org/IdmUX Test script: --------------- <?php $a = [0, 1, 2, 3, 3, 3]; $b = array_unique($a); $b[] = 4; var_dump($b); -- Edit bug report at https://bugs.php.net/bug.php?id=76971&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=76971&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=76971&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=76971&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=76971&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=76971&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=76971&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=76971&r=needscript Try newer version: https://bugs.php.net/fix.php?id=76971&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=76971&r=support Expected behavior: https://bugs.php.net/fix.php?id=76971&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=76971&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=76971&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=76971&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=76971&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=76971&r=dst IIS Stability: https://bugs.php.net/fix.php?id=76971&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=76971&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=76971&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=76971&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=76971&r=mysqlcfg
