Help me resolve this issue (from the error log) OOP PHP

I'm trying to run an OOP PHP app on my host site.

The error log says this

require_once(lib/Job.php): failed to open stream: No such file or directory in ...etc path...

So I think the issue is with this line in my init.php file

require_once 'lib/'.$class_name. '.php';

Could the issue be with my relative path? The lib directory is one level up.

Thanks

If you say lib directory is one level up, have you tried with:

require_once '../lib/'.$class_name. '.php';

Level 6

I solved it thanks
