note 127626 added to function.array-filter

Note that a filtered array no longer encodes to json arrays, as the indices are no longer continuous: $a = ['a', 'b', 'c']; var_dump(json_encode($a)); // ["a","b","c"] $a = array_filter($a, function ($x) { return $x == 'b'; }); var_dump(json_encode($a)); // {"1": "b"} you can use array_values get a continuous array var_dump(json_encode(array_values($a))); // ["b"] ---- Server IP: 45.112.84.4 Probable Submitter: 185.85.3.173 (proxied: 2a02:908:2813:f280::617b) ---- Manual Page -- https://php.net/manual/en/function.array-filter.php Edit -- https://main.php.net/note/edit/127626 Del: integrated -- https://main.php.net/note/delete/127626/integrated Del: useless -- https://main.php.net/note/delete/127626/useless Del: bad code -- https://main.php.net/note/delete/127626/bad+code Del: spam -- https://main.php.net/note/delete/127626/spam Del: non-english -- https://main.php.net/note/delete/127626/non-english Del: in docs -- https://main.php.net/note/delete/127626/in+docs Del: other reasons-- https://main.php.net/note/delete/127626 Reject -- https://main.php.net/note/reject/127626 Search -- https://main.php.net/manage/user-notes.php
