note 130470 added to function.array-multisort

Be aware with array_multisort() and array_column() when you don't want to sort all columns. The last arg ...$rest is used to sort too! <?php $data = [ ['id' => 5, 'name' => 'Marie'], ['id' => 7, 'name' => 'Lisa'], ['id' => 4, 'name' => 'Marie'], ['id' => 3, 'name' => 'Jean'], ['id' => 1, 'name' => 'Marie'], ['id' => 2, 'name' => 'Jean'], ]; array_multisort( array_column($data, 'name'), SORT_ASC, SORT_REGULAR, $data, ); /* We could guess : 3 Jean 2 Jean 7 Lisa 5 Marie 4 Marie 1 Marie But the result is : 2 Jean 3 Jean 7 Lisa 1 Marie 4 Marie 5 Marie ... id column has been sorted too! */ ---- Server IP: 45.112.84.4 Probable Submitter: 80.90.5.137 (proxied: 2a01:e0a:591:bc70:9c64:815:49b8:b603) ---- Manual Page -- https://php.net/manual/en/function.array-multisort.php Edit -- https://main.php.net/note/edit/130470 Del: integrated -- https://main.php.net/note/delete/130470/integrated Del: useless -- https://main.php.net/note/delete/130470/useless Del: bad code -- https://main.php.net/note/delete/130470/bad+code Del: spam -- https://main.php.net/note/delete/130470/spam Del: non-english -- https://main.php.net/note/delete/130470/non-english Del: in docs -- https://main.php.net/note/delete/130470/in+docs Del: other reasons-- https://main.php.net/note/delete/130470 Reject -- https://main.php.net/note/reject/130470 Search -- https://main.php.net/manage/user-notes.php
