How can PHP be optimized to handle frequent page reloads without affecting the progress calculation?

To optimize PHP to handle frequent page reloads without affecting progress calculation, you can use session variables to store the progress data and retrieve it on subsequent page loads. This way, the progress calculation can continue seamlessly across page reloads without losing any data. 

<?php
session_start();

// Check if progress data is already stored in session
if(isset($_SESSION['progress'])){
    $progress = $_SESSION['progress'];
} else {
    $progress = 0;
}

// Perform progress calculation
$progress += 10;

// Store updated progress data in session
$_SESSION['progress'] = $progress;

// Output progress
echo "Progress: " . $progress . "%";
?>
