PHP Code to Print Fibonacci Series

Write a PHP code to print Fibonacci series. In this tutorial, We are going to write a PHP script which prints Fibonacci series from 1 to N, where N is an input integer.

In this tutorial, We going to print fibonacci series in PHP using both iterative and recursive approach.

Before writing program let’s understand what is Fibonacci series.

What is Fibonacci Series?

The Fibonacci series is the series of numbers such as 0, 1, 1, 2, 3, 5,…… in which the next number is the sum of two previous numbers.

In Fibonacci series, the first two numbers are 0, 1 or 1, 1 and next number is the sum of previous two numbers.

An Algorithm to Print Fibonacci Series

i) Initialize first and second number.
first = 0 and  second = 1.

ii) Print both first and second number.

iii) Loop from index 2 to N. So third number is the sum of first and second.

PHP Code to Print Fibonacci Series using Iterative Approach

Let’s write a PHP function, which takes a number as an argument and print Fibonacci Series up to that number. Here I am writing code using an iterative approach.

Output:

PHP Code to Print Fibonacci Series using Recursion

So far we have discussed the logic of Fibonacci series. I have written a PHP code to generate a fibonacci series using an iterative approach. Now let’s write a code to print fibonacci series in PHP using recursion.
