About This Software

When a user clicks a download link, PHP should send the appropriate headers to instruct the browser to download the file rather than display it. The key is using the Content-Disposition header with the 'attachment' value, combined with setting the correct Content-Type header. This approach works for various file types including PDFs, images, archives, and documents. You'll also need to handle file reading and output properly to ensure the download works correctly across different browsers and file types.
