Убрать из массива по два элемента, через два
- $array = array_combine(range('a', 'z'), range(0, 25));
- echo '<pre>' . print_r($array, true) . '</pre>';
- $new_array = [];
- foreach (array_chunk($array, 2, true) as $key => $value) {
- ($key & 1) ?: $new_array += $value;
- }
- echo '<pre>' . print_r($new_array, true) . '</pre>';
