It is necessary to restrict PHP's access to the server's file system (specifically, to prohibit leaving the home directory).
This can be quite simply implemented through the open_basedir directive , however, in this case, the scripts start to work slower than usual, in particular, some users claim that the delay in queries to the database is more than a second per 1 request.

Answer 1

As an option - Build a docker container in which the php project will run. Even if someone tries to go beyond the home directory through PHP, he will not see anything, because the scripts work inside the container.
