This question is very important in terms of technical interviews.

You can check my previous post for PHP script to print Fibonacci series. Before solving this problem, Let’s first understand what is Recursion?

## What is Recursion?

In recursion, A function calls itself until the base condition is reached. Recursive code is much cleaner and shorter as compared to iterative code.
For better understanding you can check my previous post on recursion and what’s the difference between recursion and iteration.
