I have set apache so that all requests go to a file /var/www/common_index.php
Now, common_index.php looks at requested file name and sources appropriate file /var/www/123/public_html/requested_file.php
I am having problems when I include a file (with relative path) in requested_file.php. It tries to search for file in /var/www instead of /var/www/123/public_html/
How to solve this?
