What should I do if php7 cannot download pdf files? Let’s talk about solutions.

php7 is a programming language that itself does not involve operations such as file downloading. If you are having trouble downloading PDF files, it may be caused by a problem with your code or server configuration. Here are some possible solutions:

1. Check that the file path and name are correct.
2. Confirm that your server configuration allows downloading of PDF files and that file permissions are correct.
3. Make sure your code correctly sets the correct response headers Content-Disposition and Content-Type.
4. If you are using a framework or library, check that they handle file downloads correctly.

If none of the above methods work, you can find the problem by turning on PHP's debug mode and looking at the error logs.
