How to count elements inside array/object on PHP? -
i have array being sent view
array ( [0] => stdclass object ( [emg_id] => 2 [fkit] => 1 [door] => ) ) i count how many elements empty, null, or '0'.
i tried using count returns '1', instead of counting of elements, can later determine satisfy conditions above.
any ideas i'm doing wrong?
// number of "null" elements echo count(array_filter((array) $array[0], 'is_null')); there other is_*()-functions built-in, may example count number of strings (and on).
to test, if element (e.g.) 0, suggest use anonymous function
echo count(array_filter((array) $array[0], function ($item) { return $item === 0; })); the other cases similar.
