Introduction
Write a PHP program to find the Fibonacci series
What is the Fibonacci series?
The Fibonacci series is the one in which you will get your next number by adding the previous 2 numbers.
Method No 1: Recursive way
Write a PHP program to find the Fibonacci series
<?php
// Recursive function
function Fibonacci($number){
if ($number == 0)
return 0;
else if ($number == 1)
return 1;
// Recursive Call to get numbers
else
return (Fibonacci($number-1) +
Fibonacci($number-2));
}
$number = 10;
for ($counter = 0; $counter < $number; $counter++){
echo Fibonacci($counter),' ';
}
?>Method No 2: Iterative way
<?php
function Fibonacci($n){
$num1 = 0;
$num2 = 1;
$counter = 0;
while ($counter < $n){
echo ' '.$num1;
$num3 = $num2 + $num1;
$num1 = $num2;
$num2 = $num3;
$counter = $counter + 1;
}
}
$n = 10;
Fibonacci($n);
?>Result
