I hope you are doing well. I have been working on PHP lately and came across a concept that confused me a bit. I am currently trying to understand the difference between "GLOBAL" and "STATIC" variables in PHP. I have tried browsing through some documentation, but I am still not clear about the distinction between these two.
From what I understand, a global variable is declared outside of any function and is accessible throughout the entire script. It means that any part of the code can access and modify the global variable's value. However, I'm not quite sure how it works in practice or why one would use a global variable instead of passing values as arguments to functions.
On the other hand, I have also read about static variables in PHP, which are declared within a function but retain their value even after the function has finished executing. I believe that static variables are also accessible only within the function they are declared in, but I am not entirely clear on the reasons for using them and how they differ from global variables.
I would greatly appreciate it if someone could shed some light on this matter and provide some examples or scenarios where using global or static variables would be beneficial.
Thank you in advance for your assistance!
