I know I can just upload the file to a folder in my server, save the directory location to the MYSQL database, and create a download link based on that directory location but what happens when you store a file like a pdf or zip archive directly on the MYSQL database? How do you retrieve that data and create a file download link then?

You will have to set some content headers before outputting the data from your database, like:
header("Content-type: $type"); header("Content-length: $size"); header("Content-Disposition: attachment; filename=$name"); header("Content-Description: PHP Generated Data"); echo $data;
