What potential issues can arise when trying to automatically reload a page after using the history.back() function in PHP?

Potential issues that can arise when trying to automatically reload a page after using the history.back() function in PHP include the possibility of an infinite loop if the page continuously reloads after navigating back. To solve this issue, you can check if the page was loaded as a result of a history.back() action using a session variable, and only trigger the reload if it wasn't. 

// Check if the page was loaded as a result of a history.back() action
session_start();
if(!isset($_SESSION['from_history_back'])) {
    $_SESSION['from_history_back'] = true;
    header("Refresh:0");
} else {
    unset($_SESSION['from_history_back']);
}
