php 算法之分割数组,不用array_chunk()

用php写算法分割数组,不用array_chunk();算法如下所示。

 $value) {
        // 是否存在这个值
        if (! isset($newarray[$i])) {
            $newarray[$i] = array();
        }
        if (count($newarray[$i]) < $size) { // 先判断的问题
            if ($preserve_keys == false) {
                $newarray[$i][] = $value;
            } else {
                $newarray[$i][$key] = $value;
            }
        } else {
               $i++;
            if ($preserve_keys == false) {
                $newarray[$i][] = $value;
            } else {
                $newarray[$i][$key] = $value;
            }
        }
    }
    return $newarray;
}
  
  $array=array(1,2,3,4,5,6,7);
  print_r(array_chunk_list($array, 2,true));
