Check a Session Variable existence
Quote:
This is a small code use session for Validation



Remember : Write Session_start(); function in first line , because in some servers the session will
start automatic and it can't start the session twice so will be an warring.

Code:
        session_start();
        $valid="msi";
        $_SESSION['valid']=$valid;
        session_register('valid');

echo "next page"; 


Code:
session_start();
    if(isset($_SESSION['valid']))
     {
      echo " Session is valid ";
     }
       echo " Session is valid ";
