基于登录状态PHP的条件显示链接

Question

I have a small site which has 200 members. Below is code for the login/logout links which display a "Change Password", "Report" and "Logout" link when logged in. While not logged in, the "Login" and "Forgot password" links are displayed.

Recently we ran a competition which had 14 winners and what I am trying to achieve is to put a link into the code that only the 14 winners can see and not the remaining members.

I'm not quite sure where to start, is it possible to put a condition in this code for the 14 user ids/email addresses or would I be better off putting a new field into the user's database? Any help or push in the right direction would be appreciated!

     <?php # loginnav.php> 

     // Display links based upon the login status. 

     // Show LOGIN links if this is the LOGOUT page. 

      if (isset($_SESSION['user_id']) 
      AND (substr($_SERVER['PHP_SELF'], -10) 
      !='logout.php')) 

      { echo 
      '<li><a href="logout.php">Logout</a></li>
       <li><a href="change_password.php">Change Password</a></li> 
       <li><a href="report.php">Report</a></li>  
     '; } else { 

     // Not logged in.   
     echo 
     ' <li><a href="login.php">Login</a></li> 
     <li><a href="forgot_password.php">Forgot Password?</a></li> 
      '; } ?>

Answer 1

     $winners_array = array('userid1', 'userid2', 'userid3', 'userid4', ...);  
          // This array contains users IDs who are winners
          // You can write it manualy right intj the login file, 
          //include it from external file or form from your Data Base

    if (isset($_SESSION['user_id']) 
      AND (substr($_SERVER['PHP_SELF'], -10) 
      !='logout.php')) 
      { 
      echo 
      '<li><a href="logout.php">Logout</a></li>
       <li><a href="change_password.php">Change Password</a></li> 
       <li><a href="report.php">Report</a></li>  
      '; 
      if(in_array($_SESSION['user_id'], $winners_array)){
         // If current ID is in winners list we add special link for him
         echo '<li><a href="winer_page.php">Winner link</a></li>';
      }
      } else { 
     // Not logged in.   
     echo 
     ' <li><a href="login.php">Login</a></li> 
     <li><a href="forgot_password.php">Forgot Password?</a></li> 
      '; } ?>
