php eregi() problem

I have this problem with my code, the page is redirecting and wouldn't stop.. The browser stop it 开发者_开发知识库because it's redirecting all the time, and I have a global.php file that included in all php pages, so I putted this code for the session and it went like what I said

if (!session_is_registered('username')) {
    if(!eregi('login.php', $PHP_SELF)) header('Location: login.php');
}

Also global.php included in login.php, but when I start it on the web server of my site, it does what i said before, but on my based server on computer it works fine, so please help me fast

and sorry for my english..

Try this:

session_start();
if (!isset($_SESSION['username']) && stripos($_SERVER['PHP_SELF'], 'login.php') === false) {
    header('Location: login.php');
}

Both session_is_registered() and eregi() are deprecated functions and shouldn't be used. Plus, regular expressions are overkill for what you're doing anyways.

Try:

if (!isset($_SESSION('username'))) {
    if(FALSE === strpos($_SERVER['PHP_SELF'], 'login.php')) {
      header('Location: login.php');
      exit();
    }
}

Some Suggestions:

• Make sure that you have session_start() placed on top of your script
• Use isset($_SESSION.......
• Use strpos instead of deprecated eregi
• Don't use deprecated session_is_registered
• Use exit/die after header redirect
• It is $_SERVER['PHP_SELF'] not $PHP_SELF

• Use error handling, put these lines on top of your script:

  • ini_set('display_errors', true);
  • error_reporting(E_ALL);
