我想对数组进行排序以重新索引其键。 我尝试使用自定义循环,但它不起作用。 有这样的PHP功能吗? 我有一个像这样的数组:
Array
(
[3] => Array
(
[id] => 44
[name] => 1495714823.jpg
)
[1] => Array
(
[id] => 48
[name] => 1495795384.jpg
)
[2] => Array
(
[id] => 11
[name] => 1495602099.jpg
)
)
我需要像这样排序数组:
Array
(
[1] => Array
(
[id] => 48
[name] => 1495795384.jpg
)
[2] => Array
(
[id] => 11
[name] => 1495602099.jpg
)
[3] => Array
(
[id] => 44
[name] => 1495714823.jpg
)
)
我尝试了一些排序功能,但它没有用。
