/**
* Script to create an SQL dump file with the data to
* re-create a course in a running database, based on a separate
* running backup DB which this script must connect to.
* You will need an installation of Chamilo to be (temporarily) pointing
* at this old database (e.g. modifying the configuration.php for that).
* This script is based on the normal basic structure of a Chamilo 1.11.
* It only works at one level of depth at this point, so if you have a
* resource that points to a resource that points to a course, this will
* not be recovered. Only tables with a clear "c_id" field will be.
*
* In this first version, this script works by a destructive manner: it
* will go through the database and remove everything unrelated to the course!
* Make sure you don't run this on a production database or you will be left
* with nothing but these course resources!!!
*
* Apart from this (partial) script, there is a better, more efficient way to
* do a course restore currently, which doesn't evolve emptying a database.
* It is described at https://beeznest.com/fr/2021/06/07/comment-recuperer-un-cours-specifique-dun-backup-de-chamilo/
* and involves making a list of all tables that require a restore and
* issuing a mysqldump command with the --where='c_id=10' argument, which will
* only export whatever has a c_id of 10. There are some variations
* (explained in the article) but this will result in something similar to what
* this script currently does.
