PHP set_include_path include wondering how to handle

PHP Set_include_path include doubts
1. Assume that there are config.php files in the include/directory
2. If using Set_include_path ('.. /include ')
3. If you want to index.php with config, just include (' config.php ').

Question: Then I just need to include (' config.php ') on other pages, or Set_include_path ('. /include ') in include (' config.php ')?
Can't he cross-page, or cross-catalog?


------Solution--------------------
Plus: Set_include_path ('. /include '); The premise is that other files must be in the same sibling directory as your index.php file.
------Solution--------------------
Don't ever use zendframework, you can try not to know. Maybe it can.

Oh, well, thank you, is that the same thing in the zendframework? ZF seems to be index.php in the other after the other does not need to like this writing load::class loaded
