How to attach multiple pdfs from directory (in server) to email attachments in PHP

I made a form that can send form details to database then convert results to pdf (*pdfcrowd).

I have saved the filename(*of the pdf) inside the database and the pdf is saved inside a folder directory too.

Everything is working fine. EXCEPT that i'm stuck on how to get the pdf files. The user is going to see the tables. I'll provide a checkbox and when the checkbox is clicked, the filename in the row should be included on what to attach in the email.

My database is Recipes, Table: Recipe_list, The field w开发者_如何学Pythonhere filename is saved is.. "recipe_name" and the folder where the pdfs files are inside "/recipes/" folder.

I don't understand the "MIME" and other stuff about email attachment. I would appreciate if you can help me with this.
