如图所示是一个二维数组[别纠结,为了方便我将其转为了json], 其中type只有两个值1和2,
现在需要将type=1的元素转到$new数组中,type=2的转到$old数组中。
除了用循环还有什么方法没?
附上json:

array_column — 返回数组中指定的一列 (注意版本要求。php 5 >= 5.5.0)

除了不循环，我想不到别的法子，关注一下，等高人回答。
array_map(function($v){ if($v['type'] == 1){ $globals['new'][] = $v; }else if($v['type'] == 2){ $globals['old'][] = $v; } }, json_decode($json, true));
$arr = [];//给的数组$result = array_map(function($v){ if($v['type'] == 1) return $v;},$arr);var_dump($result);
