I've searched a lot yesterday. Found also a lot of codes. One example: PHP File Upload The second sentence: I found, that there can be a lot of vulnerabilities. Where can I look for a very secure upload form? Does somebody have an idea? Or should I do not program it with php?

Hello. I want to make a simple website, where I can upload a zip file and download it from a URL with just HTTP GET request. When I download the file, the file will then be deleted on the server. Can't find any examples. Maybe, I've searched wrong. Has somebody some written project links or some tips for me how can I achieve this?
