How can PHP sessions be utilized to control the loading of specific files or content only once during a user's browsing session?

To control the loading of specific files or content only once during a user's browsing session, you can utilize PHP sessions to set a flag once the content has been loaded and then check this flag before loading the content again. 

<?php
session_start();

if (!isset($_SESSION['content_loaded'])) {
    // Load the specific file or content here

    // Set the flag to indicate that the content has been loaded
    $_SESSION['content_loaded'] = true;
}
?>
