Previous Comments: ------------------------------------------------------------------------ [2021-02-02 19:24:50] donatj at gmail dot com 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 this bug report at https://bugs.php.net/bug.php?id=80699&edit=1
