I hope you're all doing well. I have a question about calling variables from an inner PHP function to use in an outer function. I've been working on a project, and I have a situation where I need to access a variable that is defined inside an inner function, but I want to use it in an outer function. I'm relatively new to PHP, so I'm not quite sure how to approach this.
To give you some context, I have an outer function that takes an argument and then calls an inner function. Within the inner function, I perform some calculations and assign a value to a variable. Now, I want to use this calculated value in the outer function's logic.
I've tried setting the variable as a global variable before the inner function, but it didn't seem to work. I also attempted to return the calculated value from the inner function and then pass it as an argument to the outer function, but that didn't work either.
I would appreciate any insights or suggestions on how to solve this issue. Are there any special ways to call variables from inner functions in PHP? Am I missing something obvious?
Thanks in advance for your time and help.
