title: Index "server_name" not exist
body: <p>I try to execute a bat, and in this file i try to acceed to this variable :</p>
  
  <p><code>$_SERVER['SERVER_NAME']</code></p>
  
  <p>But it doesn't exist this index. In fact, when i try to <code>print_r($_SERVER)</code>, there is no  <code>SERVER_NAME</code> index. There is a reason ? Is it because i launch this function in a bat ? 
  Have I an other solution for get this variable ?</p>
  
  <p>Thank you !</p>
