A VBScript equivalent of PHP’s array_key_exists

Function array_key_exists(key, sAry)

    array_key_exists = false
    If isObject(sAry) Then
        if sAry.Exists( key ) then array_key_exists = true
    ElseIf isArray(sAry) and isNumeric(key) Then
        If (uBound(sAry)+1) > key Then
            If Not isNull(sAry(key)) Then array_key_exists = true
        End If
    End If

End Function
