Req #73735 [Opn]: array_column keys should be preserved

Edit report at https://bugs.php.net/bug.php?id=73735&edit=1 ID: 73735 Updated by: requinix@php.net Reported by: photon0 at gmail dot com Summary: array_column keys should be preserved Status: Open Type: Feature/Change Request Package: Arrays related Operating System: ANY PHP Version: Next Minor Version Block user comment: N Private report: N New Comment: As default behavior it makes sense, but it should be possible to explicitly invoke the behavior using arguments and I'm not sure how the change could be squeezed into the function. NULL as the $index_key? Anyway, the workaround is trivial: array_combine(array_keys($items), array_column($items, "id")) Previous Comments: ------------------------------------------------------------------------ [2016-12-13 21:27:05] photon0 at gmail dot com Description: ------------ It would increase the usability of this function if it could preserve the array's keys in the result. I was expecting this to be the default behaviour. best regards, David Lévêsque Test script: --------------- $items = array( 1 => ["id" => 1], 2 => ["id" => 4], 3 => ["id" => 9], "four" => ["id" => 16] ); var_dump(array_column($items,"id")); Expected result: ---------------- array(4) { [0]=> int(1) [1]=> int(4) [2]=> int(9) ["four"]=> int(16) } Actual result: -------------- array(4) { [0]=> int(1) [1]=> int(4) [2]=> int(9) [3]=> int(16) } ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=73735&edit=1
