Can you write a program to print the Fibonacci series in php?

Answer 1

The Fibonacci sequence uses recursion to derive answers. It is defined as: F0 = 0

F1 = 1

Fn = F(n - 1) + F(n -2) To have this sequence printed by a php script use the following:

function fibonacci($n)

{

if($n 1)

return 1; //F1

else

return fibonacci($n - 1) + fibonacci($n - 2); //Fn

} This recursive function will print out the Fibonacci number for the integer n. To make it print out all the numbers in a particular set add this to your script.

for($i = 0; $i < 15; $i++)

{

echo fibonacci($i) . "<br />";

} So your final result would look like. <?php

function fibonacci($n)

{

if($n 1)

return 1;

else

return fibonacci($n - 1) + fibonacci($n - 2);

} for($i = 0; $i < 15; $i++)

{

echo fibonacci($i) . "<br />";

}

?>
