My server is in /var/www/html I have a php script in /var/www/html/fileio_test/io_test.php
In order for this file to be readable for both the user "djameson" as well as the webserver, you need to do 4 things:
chown)of the file, so that it is owned by the user django and the group you just set up.chmod) allow read permission by the group.
