I'm currently working on a PHP project and I have a question regarding accessing constants within different scopes or files in PHP. I've defined some constants in one file and now I'm trying to access them in another file or within different scopes.
I've tried using the `define()` function to define the constants in one file, for example, `constants.php`. Then, in another file, I've tried to access them using the constant name. However, it doesn't seem to be working as expected. I'm not sure if I am missing something or if there's a different way to access constants across scopes or files.
Could someone please guide me on how to access constants within different scopes or files in PHP? I would really appreciate any help or insights you can provide. Thanks in advance!
