You can use try-catch blocks on your code/ So – on the main program enter-point you can insert the try block and on the end – catch the exception

try
{
     // include main files with functionality
}
catch ( Exception $e )
{
     // here you can log the exception text $e->getText()
     // take current user ID and set his status
     setStatus($_SESSION['user_id']);
}
