A VBScript equivalent of PHP’s array_walk

Function array_walk(ByRef arr, callback, userdata)

    Dim key

    If Len( callback ) = 0 Then Exit Function

    If isArray( arr ) Then

        For key = 0 to uBound( arr )
            execute("call " & callback & "(arr(key),key,userdata)")
        Next

    ElseIf isObject( arr ) Then

        Dim return_val

        For Each key In arr
            execute("call " & callback & "(arr.Item(key),key,userdata)")
        Next

    End If

    array_walk = true

End Function
