XML to MYSQL, script check

[White Horse]

Hello community,
I want to import this xml code to mysql - my script runs without errors but there is nothing in database.
So if there is some nice soul to check where I made mistake :shrug: i would be very thankful. I m very new to PHP (programming in general :/)

I only need these information extracted:
<description> and
<krit measurand="KRIT" unit="%">0</krit><traffic_out> under <traffic_out>

XML CODE:

 <?xml version="1.0" encoding="UTF-8" ?> 
- <!-- # wanstats 
  --> 
- <cacti>
- <report>

PHP CODE;

 
<?php
//mysql connection
$con2 = mysql_connect("localhost","cactiuser","cactiuser");

//simplexml load xml file

//loop through parsed xmlfeed and print output

foreach ($data_items->item as $item) {
              printf("Description: %s\n", $item->description);
                     foreach ($item->results as $results) {
                     printf("Traffic_out: %s\n", $results->traffic_out);
                     
                   

//insert into databse
                               mysql_query("INSERT INTO report_percent (city_id, time_over_treshold) VALUES (\"$item->description\",\"$results->traffic_out\")")
