[Hiring] PHP Security Help / RFI & LFI Prevention

Hello. I have a website that pulls in a number of pdfs and force downloads them into a zip file. Right now, my security scans come up with RFI and DFI as the high risks. I am looking to prevent it. Has anyone had any luck or experience with this? I have posted the code below. Let me know cost! Thanks!!
