Yes, it is a common convention in PHP to use all uppercase letters for class constants. This follows a similar convention to constants defined outside of classes. It makes constants easily distinguishable from variables and indicates that they are meant to be treated as immutable and global within the scope of the class.
For example:
class MyClass { const MY_CONSTANT = 'some value'; // Rest of the class code... } By convention, class constants are often named using uppercase letters and underscores to separate words. This naming style is known as "snake_case" for constants. It enhances code readability and consistency, making it clear that a particular identifier is a constant value. Remember to follow the coding standards of your project or development team, as these conventions can vary across different coding styles.
