From: donatj at gmail dot com Operating system: All PHP version: 8.0.1 Package: Scripting Engine problem Bug Type: Bug Bug description:array_map no longer passes by reference Description: ------------ array_map no longer passes by-reference. This has broken a lot of things for us. This very well may be an intentional change, but I didn't see it noted, and if it is, it should be documented on the array_map page as a change? Test script: --------------- <?php // https://3v4l.org/BdWq7 $data = array( array(1,2,3), array(4,5,6), ); $data = array_map('reset', $data); print_r($data); Expected result: ---------------- Array ( [0] => 1 [1] => 4 ) Actual result: -------------- Warning: reset(): Argument #1 ($array) must be passed by reference, value given in /in/BdWq7 on line 8 Warning: reset(): Argument #1 ($array) must be passed by reference, value given in /in/BdWq7 on line 8 Array ( [0] => 1 [1] => 4 ) -- Edit bug report at https://bugs.php.net/bug.php?id=80699&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=80699&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=80699&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=80699&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=80699&r=needscript Try newer version: https://bugs.php.net/fix.php?id=80699&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=80699&r=support Expected behavior: https://bugs.php.net/fix.php?id=80699&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=80699&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=80699&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=80699&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=80699&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=80699&r=dst IIS Stability: https://bugs.php.net/fix.php?id=80699&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=80699&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=80699&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=80699&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=80699&r=mysqlcfg
