PHP 8.4 test Recursive vs. Iterative Fibonacci using

PHP Code Editor

<?php
echo '<pre>';
// Recursive Fibonacci
function fibonacciRecursive($n) {
if ($n <= 1) return $n;
return fibonacciRecursive($n - 1) + fibonacciRecursive($n - 2);
}
// Iterative Fibonacci
function fibonacciIterative($n) {
$a = 0;
$b = 1;
for ($i = 0; $i < $n; $i++) {
$temp = $a;
$a = $b;
$b = $temp + $b;
}
return $a;
}
// Test the performance
$n = 30; // Adjust this for testing larger Fibonacci numbers
// Measure recursive performance
