php怎么将二维数组键名相同的元素转为新的数组?不用for,foreach循环

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:

<code>/*
* 好吧。不知道是不是你需要的。还有想说一句，有这个必要吗？
* */
$b =
array(
array('type' => 1, 'name' => 'lisi'),
array('type' => 2, 'name' => 'lisi'),
array('type' => 1, 'name' => 'lisi'),
array('type' => 1, 'name' => 'lisi'),
);
$newArray = array();
print_r(array_filter($b,'filtertype'));
echo '<br>';
print_r(array_filter($b,'filtertypetwo'));
function filtertype($var)
{
return $var['type'] ==1;
}
function filtertypetwo($var)
{
return $var['type'] ==2;
}</code>
array_column — 返回数组中指定的一列 (注意版本要求。PHP 5 >= 5.5.0)
<code><?php $records = array(
array(
'id' => 2135 ,
'first_name' => 'John' ,
'last_name' => 'Doe' ,
),
array(
'id' => 3245 ,
'first_name' => 'Sally' ,
'last_name' => 'Smith' ,
),
array(
'id' => 5342 ,
'first_name' => 'Jane' ,
'last_name' => 'Jones' ,
),
array(
'id' => 5623 ,
'first_name' => 'Peter' ,
'last_name' => 'Doe' ,
)
);
$first_names = array_column ( $records , 'first_name' );
print_r ( $first_names );
?>
以上例程会输出：
Array
(
[0] => John
[1] => Sally
[2] => Jane
[3] => Peter
)
</code>
除了不循环，我想不到别的法子，关注一下，等高人回答。
<code>array_map(function($v){
if($v['type'] == 1){
$GLOBALS['new'][] = $v;
}else if($v['type'] == 2){
$GLOBALS['old'][] = $v;
}
}, json_decode($json, true));</code>
<code class="php">$arr = [];//给的数组
$result = array_map(function($v){
if($v['type'] == 1) return $v;
},$arr);
var_dump($result);</code>
