I've been coding in PHP for a while now and I recently stumbled upon the concept of defining constants. I understand that constants are identifiers whose values should stay the same throughout the execution of a program. However, I'm not quite sure about the naming conventions or best practices for defining constants in PHP.
I want to make sure that my code is easy to read and maintain, so I was wondering if there are any guidelines or conventions that I should follow when naming constants. Should I use camel case or underscores? Are there any specific prefixes or suffixes that are commonly used for constants?
I would really appreciate it if anyone could share their insights or experiences in this matter. Thank you in advance!
