我只在localhost上收到PHP警告通知

I receive a PHP warning:

"Notice: A session had already been started - ignoring session_start()". 

This happens only on the localhost and not on the server.

The same file exists on server and localhost.

Why is there a variation of results ?

Here is my Code :

<?php session_start ();?>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>BookMyFilms - Register</title>
<link rel="stylesheet" type="text/css" href="css/styles.css">
</head>
</html>
<?php
$username = $_POST ['username'];
$_SESSION ['user'] = $username;
require ('includes/header.php');
require ('includes/db.php');
require ('includes/common.php');
Register ();
require ('includes/footer.php');?>

    Servers are usually configured in a "Production" environment, which don't print notices and warnings. For the other problem, you probably have another session_start in one of your next includes.
