Why is__DIR__ used in sqlite: but not in mysql:
I have a basic understanding that DIR is a magic constant that gets the directory name of the file, but I'm not sure why it's being used in sqlite and not in mysql?
What is the purpose for using DIR in sqlite, and why is it not in the teachers notes for those who are using mysql?
I fall into the category of those using mysql, so any help would be greatly appreciated.
Thanks in advance!

DIR denotes the directory where lies the script where it written. And, remember that SQLITE is simple a file. This constant ensures that you always get the absolute path to that file.

Thanks @sheacole , so does this mean we shouldn't use_DIR_ for mysql?
