PHP Fibonacci Sequence

0 votes

This PHP method should print the Fibonacci sequence up to a specified value using a for loop. But it does not work. What is wrong in this code?

<?php
function fib ($n) { // a function called fib, declaire variable n (the sequence number)
    for ($n=0;$n<30;$n++) {
        if ($n < 3) { return $n; } // if n is smaller than 3 return n (1 or 2)
        else { return fib ($n - 1) + fib ($n - 2); } 
    /* if the number is 3 or above do 2 sums (n-1) and (n-2)
    and then add the 2 sums together (n-1)+(n-2)
    Example Fibonacci number 4
    (4-1)+(4-2) = 5
    3 + 2 = 5
    */
}
print $n;
?>

Can someone please help me with this?
