What is the recommended method for handling cron jobs in a CodeIgniter application deployed on cloud hosting?

When deploying a CodeIgniter application on cloud hosting, the recommended method for handling cron jobs is to use a command-line interface (CLI) script. Here's a step-by-step guide on how to handle cron jobs in a CodeIgniter application deployed on cloud hosting:

  1. Create a CLI script: Create a new script file with a .php extension, for example, cron.php, outside the public web directory of your CodeIgniter application. This script will act as the entry point for your cron jobs.
  2. Configure the script: Inside the cron.php script, load the necessary CodeIgniter framework files and set the base path of your application. This ensures that your script has access to the application's resources. Here's an example:
define('BASEPATH', __DIR__ . '/path_to_codeigniter_system_folder/'); // Set the correct path to the CodeIgniter system folder
define('APPPATH', __DIR__ . '/path_to_codeigniter_application_folder/'); // Set the correct path to the CodeIgniter application folder

// Load CodeIgniter's index.php file
require_once __DIR__ . '/path_to_codeigniter_folder/index.php';

  1. Create a controller and method: Inside your CodeIgniter application, create a controller and a method that will handle the functionality of your cron job. For example, if you need to perform some database cleanup, create a controller called Cron with a method called cleanup that performs the necessary operations.
class Cron extends CI_Controller {
    public function cleanup() {
        // Perform the cron job's operation

  1. Run the cron job: In your cloud hosting control panel, set up a cron job and use the CLI command to execute the cron.php script. For example:
php /path_to_cron.php/cron.php cron cleanup

This command will execute the cleanup method inside the Cron controller, as defined in your CodeIgniter application.

By following these steps, you can effectively handle cron jobs in your CodeIgniter application deployed on cloud hosting.
