Title Body

I need to remove empty entries on multilevel arrays. For now I can remove entries with empty sub-arrays, but not empty arrays... confused, so do I... I think the code will help to explain better. /** * * This function remove empty entries on arrays * @param array $array */ function removeEmptysFromArray($array) { $filtered = array_filter($array, 'removeEmptyItems'); return $filtered; } /** * * This is a Callback function to use in array_filter() * @param array $item */ function removeEmptyItems($item) { if (is_array($item)) { return array_filter($item, 'removeEmptyItems'); } if (!empty($item)) { return true; } } $raw = array( 'firstname' => 'Foo', 'lastname' => 'Bar', 'nickname' => '', 'birthdate' => array( 'day' => '', 'month' => '', 'year' => '', ), 'likes' => array( 'cars' => array('Subaru Impreza WRX STi', 'Mitsubishi Evo', 'Nissan GTR'), 'bikes' => array(), ), ); print_r(removeEmptysFromArray($raw)); This code will remove nickname , birthdate but is not removing bikes that have an empty array. My question is... How to remove the bikes entry?
