A VBScript equivalent of PHP’s array_intersect

Function array_intersect(mAry1,mAry2)

    Dim key
    Dim output : set output = Server.CreateObject("Scripting.Dictionary")

    If isArray(mAry1) Then
        For key = 0 to uBound(mAry1)
            If len(array_search(mAry1(key),mAry2,false)) > 0 Then
                output.Add key, mAry1(key)
            End If
        Next
    ElseIf isObject(mAry1) Then
        For Each key In mAry1
            If len(array_search(mAry1(key),mAry2,false)) > 0 Then
                output.Add key, mAry1(key)
            End If
        Next
    End If

    set array_intersect = output

End Function
