PHP Two-dimensional array, what to do with

PHP Two-dimensional array
Array ([0] = = Array ([adminname] = Sysadm [Menuno] = =) [1] = = Array ([adminname] = 00000 [Menuno] =&G T 30,27,32) [2] = = Array ([adminname] = 00000 [Menuno] = 25,26,27) [3] = = Array ([adminname] + 00001 [ Menuno] = 30,27,32))
Array as above: How to merge AdminName the same, combine the values of Menuno into a piece
Array ([0] = = Array ([adminname] = Sysadm [Menuno] = =) [1] = = Array ([adminname] = 00000 [Menuno] =&G T 30,27,32,25,26,27) [2] = = Array ([adminname] = 00001 [Menuno] = 30,27,32))

 $ar = Array (

 1 = ar Ray (' adminname ' = ' 00000 ', ' menuno ' = ' 30,27,32 '),

Array
(
    [0] = = Array
        (
            [AdminName] = Sysadm
            
        )

    [1] = = Array
        (
            [AdminName] = 00000
            [Menuno] = 30,27,32,25,26,27
        )

    [2] = = Array
        (
            [AdminName] = 00001
            [Menuno] = 30,27,32
        )

)

This is called "clustering" in the calculation method.
