So I've been trying to learn PHP and came across the constant() function, but I'm a bit confused about how it works. I've seen some examples, but I'm still struggling to understand its purpose and how to use it effectively in my code.
From what I gather, the constant() function in PHP is used to retrieve the value of a constant. But I'm not sure when and why I would use this function instead of simply accessing the constant directly.
Can someone please explain to me the concept of the constant() function and provide me with an example that showcases its usage? The more detailed the explanation, the better! I want to make sure I fully grasp this before I continue with my PHP learning journey.
Thank you in advance!
