VBScript shuffle function

A VBScript equivalent of PHP’s shuffle

Function shuffle(ByRef arr)

    shuffle = false
    If not isArray(arr) Then Exit Function

    Dim key,j,x,i : i = count(arr,0)


    For key = 0 to uBound(arr)
        i = i -1
        j = Round(Rnd * i)
        [=] x , arr(i)
        [=] arr(i) , arr(j)
        [=] arr(j) , x

    shuffle = true

End Function
