PHP Fatal error: Unknown: Failed opening required in Unknown on line 0 about cachetool HOT 3 CLOSED

The issue is because SELinux is preventing read access to the file you are trying to access,

use restorecon /home/user/webroot/site/application/model/v2/index.php to restore access to the file

Hope this helps

from cachetool.

Use --tmp-dir to a path that SELinux does not block access to.
Feel free to reopen if the issue still persists

I had the same problem, I tried to run

docker run --t -v .:/project php

when I tried to do

/project:$ php file.php

I got this error.

Apparently, you can't use bound volumes from docker that easily. So I copied the volume inside the container, and used a copy.

docker run --t -v .:/project php

/project:$ cd ..
/:$ cp -r /project /project2
/:$ cd /project2
/project2: $ php file.php

and it worked.
