How to disable the execution of scripts (php) in the directory for downloading files?

Question

PHP

Greetings!
Please tell me how to make a directory in which users can upload files of any type, but which cannot be executed on the server.
For example, the user uploaded the file test.php, but when accessing test.ru/attach/test.php , the source code of this file will simply be downloaded.
How to do this as safely as possible?
Thank you!
UPD: I forgot to clarify that fast-cgi is used
