php:按字母顺序按键排序多维数组？

Question

我需要按键按字母顺序排序一些嵌套数组...

是否有一个本机PHP函数来对以下内容进行排序,因此嵌套数组的顺序就像

[G] - >阵列......

[I] - >数组......

[P] - >阵列......

[S] - >阵列......

[T] - >阵列......

这是一个未排序的数组示例:

[S] => Array
    (
        [26] => Array
            (
                [name] => St Georges Hall
                [tel] => sdfa
            )

        [27] => Array
            (
                [name] => St Werburghs Community Centre
                [tel] => sadf
            )
    )

[G] => Array
    (
        [40] => Array
            (
                [name] => The Golden Guinea
                [tel] => 
            )

        [41] => Array
            (
                [name] => The Golden Lion
                [tel] => One of Bristol's key live music pubs
            )

    )

[I] => Array
    (
        [45] => Array
            (
                [name] => The Island
                [tel] => asdfgf
            )

    )

[P] => Array
    (
        [50] => Array
            (
                [name] => The Prom
                [tel] => Reliable gig venue and blues hotspot on Gloucester road
            )

    )

[T] => Array
    (
        [51] => Array
            (
                [name] => The Thunderbolt
                [tel] => Small gig venue in Totterdown
            )

        [52] => Array
            (
                [name] => Tobacco Factory
                [tel] => A modern cafe-bar with regular live music.
            )

    )
