What are the common challenges faced when trying to automate PHP scripts using cronjobs?

One common challenge when automating PHP scripts using cronjobs is ensuring that the correct path to the PHP executable is specified in the cronjob command. This is important because cronjobs do not always have the same environment variables set as when running scripts manually. To solve this issue, you can specify the full path to the PHP executable in the cronjob command.

* * * * * /usr/bin/php /path/to/your/script.php
