'<html><head>'."n". '<title>404 Not Found</title>'."n". '</head><body>'."n". '<h1>Not Found</h1>'."n". '<p>The requested URL '. str_replace(strstr($_SERVER['REQUEST_URI'], '?'), '', $_SERVER['REQUEST_URI']). ' was not found on this server.</p>'."n". '</body></html>'."n"; exit; } # In any file you want to connect to the database, # and in this case we will name this file db.php # just add this line of php code (without the pound sign): # include"db.php"; # once ?>
