How can PHP developers optimize the frequency of running cleanup scripts for inactive user sessions?

To optimize the frequency of running cleanup scripts for inactive user sessions, PHP developers can set up a cron job to run the cleanup script at regular intervals. By scheduling the cleanup script to run periodically, developers can efficiently remove inactive user sessions and free up resources on the server.

<?php

// Define the path to the cleanup script
$cleanup_script = '/path/to/cleanup_script.php';

// Set up a cron job to run the cleanup script every hour
shell_exec('crontab -l | { cat; echo "0 * * * * php ' . $cleanup_script . '"; } | crontab -');
