Can PHP be used inside an XML file?

Question

I am trying to create an RSS feed from a mysql database that I already have. Can I use PHP in an XML file that needs to be sent to the user so that it generates content on demand? Or should I use cron in a PHP file and generate an xml file? Or should I add the execution of the php file that xml generates after posting the content to be used in RSS? What do you think is best practice?

Answer 1

All three approaches are technically possible. However, I would not use cron because it delays the process of updating your XML files after changing the contents of the database.
