Error with PEAR's library Net_Traceroute - El Forum - 01-14-2011

Hi guys, i am building an application that will traceroute a host and display the data on googlemap. I am currently using pear's traceroute library. Able to run the traceroute() command but it seems to throw me one error.

A PHP Error was encountered
Severity: Notice

Message: Undefined offset: 5

Filename: Net/Traceroute.php

Line Number: 531

Traceroute.php is the library class i called. It seems like it has a problem with the array associated to line 531. I can't seem to find the problem.

Below is the code of the library class

Code:
function _parseResultwindows()

    {

        $raw_data_len = count($this->_raw_data);

        $dataRow = 0;

        while (empty($this->_raw_data[$dataRow]) && ($dataRow<$raw_data_len)) {

            $dataRow++;

        }

        $tempparts = explode(' ', $this->_raw_data[$dataRow]);

        $searchIdx = 0;

        while (($searchIdx < count($tempparts)) && (substr($tempparts[$searchIdx], 0, 1) != '[')) {

            $searchIdx++;

        }

        $this->_target_ip = trim($tempparts[$searchIdx], ' [],');

        while (($searchIdx < count($tempparts)) && ((int) $tempparts[$searchIdx] <= 0)) {

            $searchIdx++;

        }

        if ((int) $tempparts[$searchIdx] > 0) {

Quote:This is Line 531------^ "if ((int) $tempparts[$searchIdx] > 0) {"

Code:
$this->_ttl = (int) $tempparts[$searchIdx]; // TTL might be written in next line; e.g. on Windows 98

        } elseif (!empty($this->_raw_data[$dataRow+1])) {

            $dataRow++;

            $tempparts  = explode(' ', $this->_raw_data[$dataRow]);

            $searchIdx = 0;

            while (($searchIdx < count($tempparts)) && ((int) $tempparts[$searchIdx] <= 0)) {

                $searchIdx++;

            }

In my controller, this is how i call the traceroute() function:

Code:
$host = $this->input->post('ip_text');

         $this->load->library('pearloader');

        $tr=$this->pearloader->load('Net_Traceroute',"", "WANXING");

         $tr = Net_Traceroute::factory();

         if(!PEAR::isError($tr)) {

      // trace route to host and get response

              $response = $tr->traceroute($host);

      // print response

              echo $response->getRawData();

        }

Everything is displaying correctly just that the error keep popping out. Any help will be deeply appreciated. I am using the lastest release of Traceroute package from PEAR--> version 0.21.3
