 The website is built entirely from scratch using pure PHP, without relying on any frameworks. This was done as an experimental project to enhance personal skills. Despite this, some libraries were used to add specific functionality:
 
 - [\[PHP\] PHPMailer](https://github.com/PHPMailer/PHPMailer): A library for sending emails, used for password recovery functionality.
+- [\[PHP\] FPHP](https://www.fpdf.org/): library which allows to generate PDF files with pure PHP, that is to say without using the PDFlib library.
 - [\[JS\] Swiper.js](https://github.com/nolimits4web/swiper): A highly customizable library for creating sliders and carousels.
 - [\[JS\] Toastify.js](https://github.com/apvarun/toastify-js): A lightweight library for creating beautiful and customizable toast notifications.
