Why can't www-data read /usr/share?

Question

linux

I want to fill one gap in my *nix knowledge, but I don't even know what to google.
The essence of my gap in one question:
There is a directory /usr/share , the owner and group are root , the rights are standard, i.e. 755 for directories and 644 for files. These rights ALLOW to read, namely to read files and folders to any user of the system.
There is one Apache in conjunction with PHP, which runs under the www-data user . And he... IS FORBIDDEN to access the /usr/share directory! Tellingly, the same phpMyAdmin from /usr/share/phpmyadmin runs under the www-data user, and everything is readable!
WHY?! Clarify please! Or poke into the correct manuals explaining this alignment.
Why do I need it: I want to make a directory in which common php libraries will be stored, for inclusion from any virtual host, in read-only mode.

Answer 1

How did you determine that he was denied access?

Answer 2

Perhaps directly in the Apache settings is prohibited.
See /etc/apache/apache2.conf (or whatever distribution you have) in the block

<Directory /usr/share>
.....
</Directory>

Answer 3

is_readable only checks if it is possible to get file_get_contents() and the like, therefore, in case of a 403 response, the function will return FALSE, even if the directory is readable, Options -Indexes or another similar prohibition in the config just worked.

Answer 4

your problem

sudo gedit /etc/modprobe.d/asus.conf
A text file will open. Add a line to the end there.
options asus_nb_wmi wapf=4
Save the file and reboot. Should work.
