I'm currently working on a PHP project and I've encountered a situation where I need to use static variables within a function. I've heard that static variables retain their value even after the function ends, and they are quite useful in some scenarios. However, I'm not exactly sure how to go about using them correctly.
To provide some context, I have a function that is called multiple times within my code. This function performs a specific task, but it needs to keep track of some information that shouldn't be reset every time the function is called. I believe that using static variables might be the solution to this problem.
I would greatly appreciate it if someone could guide me on how to properly use static variables within a function in PHP. Are there any specific rules or syntax I should be aware of? Additionally, if there are any potential pitfalls or best practices I should consider, I'd love to hear about those too.
Thanks in advance for any help you can provide!
