PHP的：按字母順序排序多維數組？

Question

我需要按其鍵的字母順序對一些嵌套數組進行排序...

是否有本機PHP函數可以對以下內容進行排序，以便嵌套數組像

[G]->數組...

[I]->數組...

[P]->數組...

[S]->數組...

[T]->數組...

這是一個未排序數組的示例：

[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.
            )

    )
