Prompt Title: PHP CI Helper Performance

To use the LocationHelper efficiently in PHP CodeIgniter, you can use the autoload feature to load the helper only once instead of calling it in every PHP file.

First, you can open the autoload.php file located in the config directory and add the LocationHelper to the $autoload['helper'] array. This will ensure that the helper is loaded automatically on every page load.

phpCopy code
$autoload['helper'] = array('location');

Next, you can remove the use App\Helpers\LocationHelper; line from all the PHP files where the helper is being used. This is because the helper is now being loaded automatically via the autoload feature, so you don't need to manually include it in each PHP file.

Finally, you can call the helper function as follows:

phpCopy code
$country = getTwoLetterCountryCode();

This approach ensures that the helper is loaded only once and is available for use throughout the application without the need for manual inclusion in every PHP file. This can improve the overall performance of the application and make the code easier to manage.
