What are the advantages and disadvantages of using cronjobs for time-based events in PHP?

Cronjobs are useful for automating time-based events in PHP, such as running scheduled tasks or scripts at specific intervals. However, they require access to server settings and can be complex to set up for beginners. Additionally, they may not be suitable for tasks that need to be triggered based on user interactions or real-time events.

// Example of setting up a cronjob in PHP
// Add this line to your crontab file to run a script every day at 2am
// 0 2 * * * /usr/bin/php /path/to/your/script.php

// script.php
echo "This script runs every day at 2am";
