I am currently working on a PHP project and I am facing some confusion regarding setting a top-level or super duper global variable in PHP. I have been working with PHP for a while now, but I'm still relatively new to the concept of top-level or super duper global variables.
The reason I'm looking to set a top-level or super duper global variable is that I need a variable that can be accessed from any part of my PHP code, regardless of the scope. I want to avoid having to pass this variable as a parameter or declare it within each function separately.
I have read some articles and tutorials, but I am not sure about the correct syntax or approach to achieve this. I have seen some examples using the "global" keyword inside a function, but I'm not sure if that is the best way to create a top-level or super duper global variable.
So, my question is: What is the correct way to set a top-level or super duper global variable in PHP? Can someone please provide me with an example or explain the syntax and approach to accomplish this? It would be really helpful if you could also explain any potential pitfalls or best practices to keep in mind while using top-level or super duper global variables.
Thank you in advance for your assistance!
