What potential pitfalls should be considered when automatically reloading a page in PHP?

One potential pitfall when automatically reloading a page in PHP is the risk of creating an infinite loop if not properly handled. To avoid this, you can use a conditional check to limit the number of reloads or use a session variable to track reloads. Additionally, consider implementing a delay between reloads to prevent overwhelming the server. 

<?php
session_start();

if(!isset($_SESSION['reload_count'])) {
    $_SESSION['reload_count'] = 1;
} else {
    $_SESSION['reload_count']++;
}

if($_SESSION['reload_count'] <= 3) {
    header("Refresh: 5"); // Reload the page after 5 seconds
} else {
    echo "Reload limit reached.";
}
?>
