I've been working on a PHP project recently and came across the concept of constants. From what I understand, constants are like variables, but their value cannot be changed once they are defined.
However, I'm a bit confused about the scope of constants in PHP. I know that variables can have different scopes, such as local scope, global scope, and static scope. But what about constants? Do they also have different scopes, or are they always accessible throughout my PHP code?
I would really appreciate if someone could clarify this for me. Thank you in advance for your help!
