For the BIN database, please download the DB11.LITE BIN file for testing.

How do I test my modifications?

We will issue every participant a dedicated testing account on our test server. You will need to login to our server to evaluate the query time. This is to make sure that all participants are benchmarking their query times using the same hardware environment. We wil use the same test server to re-evaluate your modified PHP library.

Below are the procedures for the testing.

  2. Change the directory to resources.
    cd resources
  3. Open the IP2Location.php file using vi editor, and replace the code with your submission codes.
    vi IP2Location.php
  4. Run the test script.
    php test.php
  5. Open testing_report.txt to view the total time taken for query.

How do I submit my improved version of IP2Location PHP Library?

You are required to submit your optimized PHP library file, IP2Location.php at submission page. We will re-test your library file for the query time result. After that, we will email you the result that we obtained, and this result will be the official result for us to determine the final winner.

Can I know my current ranking?

We will publish the best query time that we have obtained from participants' submissions at the submission page. You may use this information to gauge your benchmark data.
