有个数组
我想让红框里的键值连续0123456789而不是每次都重新0123，0123想道用array_merge重新整合，但是不知道循环该怎么写麻烦各位给个思路或者新的好方法
光阴似箭催人老，日月如移越少年。
function merge($prev, $now) { return array_merge($prev, $now['item_data']); } array_reduce($arr, "merge", array());

function arr_merge($arr) { static $str; if (!is_array($arr)) { return $arr; } foreach ($arr as $key => $val ) { if (is_array($val)) { arr_merge($val); } else { $str[] = $val; } } return $str; }
