Find or list all constants used in a PHP file

Question

How to manage constants?

I am using zencart for my site.

I add all global constants in:

includes/languages/english/english.php
         


        

Answer 1

some ides, like netbeans, phpstorm, and probably many others have features like "find usages" and "refactor" which are really useful when renaming/updating/deleting, and they support constants.

this doesn't tell you "what comments are used in a specific file", but, i'm guessing its useful to you for similar purposes.
