VBScript array_diff_key function

A VBScript equivalent of PHP’s array_diff_key

Function array_diff_key(ByVal mAry1,ByVal mAry2)

    Dim arr_dif
    set arr_dif = Server.CreateObject("Scripting.Dictionary")

    If Not isObject(mAry1) then
        set array_diff_uassoc = arr_dif
        Exit Function
    End If

    Dim key
    For Each key In mAry1
        arr_dif.Add key, mAry1(key)

    If isObject(mAry2) Then
        For Each key In mAry2
            If arr_dif.Exists( key ) Then arr_dif.Remove key
    End If

    set array_diff_key = arr_dif

End Function
