What are the best practices for setting up cronjobs in PHP to run at specific times?

When setting up cronjobs in PHP to run at specific times, it is important to ensure that the correct syntax is used in the cronjob command and to specify the full path to the PHP executable. Additionally, it is recommended to log the output of the cronjob to a file for debugging purposes.

// Example of setting up a cronjob in PHP to run a script every day at 3:00 AM
// Add the following line to your crontab file (use 'crontab -e' to edit):
// 0 3 * * * /usr/bin/php /path/to/your/script.php >> /path/to/logfile.log 2>&1
