Are there any built-in PHP functions available to display the remaining session time to users, or is a custom solution necessary?

To display the remaining session time to users in PHP, you can calculate the remaining time by subtracting the current time from the session expiration time. There are no built-in PHP functions specifically for this purpose, so a custom solution is necessary. You can store the session expiration time in a session variable and then calculate the remaining time using PHP's date and time functions. 

// Set session expiration time (e.g., 30 minutes from now)
$_SESSION['expiration_time'] = time() + (30 * 60);

// Calculate remaining time
$remaining_time = $_SESSION['expiration_time'] - time();

// Display remaining time to users
echo "Session will expire in " . gmdate("i:s", $remaining_time) . " minutes";
