What is usually a good approach is to setup specific directories where
Apache can write (like "files" or "images") and then disable PHP/other
code execution from that directory. So if someone is able to hack your
web app and upload something (malicious code) into that directory, it
won't get executed.

To put it briefly: keep your executable code and upload directories separate.
