$num=$_POST['nm1'];
for($i=2;$i<=$num-1;$i++)
{
$fibo[$i]=$fibo[$i-1]+$fibo[$i-2];

We'll show an example to print the first 12 numbers of a Fibonacci series.
<?php
$num = 0;
$n1 = 0;
$n2 = 1;
echo "<h3>Fibonacci series for first 12 numbers: </h3>";
echo "\n";
echo $n1.' '.$n2.' ';
while ($num < 10 )
{
$n3 = $n2 + $n1;
echo $n3.' ';
$n1 = $n2;
$n2 = $n3;
$num = $num + 1;
?>
Output:
PHP Fibonacci series 1
Fibonacci series using Recursive function
Recursion is a phenomenon in which the recursion function calls itself until the base condition is reached.
<?php
/* Print fiboancci series upto 12 elements. */
$num = 12;
echo "<h3>Fibonacci series using recursive function:</h3>";
echo "\n";
/* Recursive function for fibonacci series. */
function series($num){
if($num == 0){
return 0;
}else if( $num == 1){
return 1;
} else {
return (series($num-1) + series($num-2));
}
}
/* Call Function. */
for ($i = 0; $i < $num; $i++){
echo series($i);
echo "\n";
}
