我有这个数组：
Array
(
[702a4584] => Array
(
[type] => folder
[id] => 702a4584
)
[b547b3a9] => Array
(
[type] => folder
[id] => b547b3a9
)
[fcb0d055] => Array
(
[type] => page
[id] => fcb0d055
)
)
我想过滤数组,只保留类型“文件夹”：
Array
(
[702a4584] => Array
(
[type] => folder
[id] => 702a4584
)
[b547b3a9] => Array
(
[type] => folder
[id] => b547b3a9
)
)
我可以做到这一点,但我需要一个通用的功能：
$temp = array();
foreach($array as $key => $value)
{
if($value['type'] =="folder")
{
$temp[$key] = $value;
}
}
你可以使用

$filtered = array_filter($array,function($v) { return $v['type'] == 'folder'; });
