Answer 1

This function has been DEPRECATED as of PHP 5.3.0 and REMOVED as of PHP 5.4.0.

Ref: http://www.php.net/manual/en/function.session-register.php

Dont use session_register(), session_is_registered() and session_unregister()

You can use $_SESSION[] instead of that

Like as mentioned below:

$_SESSION['username']= "Your value";

Answer 2

Do not use session_register("myusername"); instead use

$_SESSION['username']= "username"; // storing username in session

session_register function has been deprecated since PHP5.3

Answer 3

Use isset($_SESSION['username']) for check session Like as:

if(!isset($_SESSION['username'])){
   // go to login page code here.
    // in login page, store data into session, use following:
    $_SESSION['username']="username";
}
else{
   $username=$_SESSION['username'];// get previous session and go your project page
}

session_register() function has been deprecated since PHP5.3
