Difference between session-register and $_SESSION in PHP

Difference between session-register and $_SESSION in PHP

 

I read in the help http://www.php.net/session_register that using $_SESSION[var]=value is better than using session_register. It is because session_register() only works if register_globals is set ON in your php.ini file, but for security purposes this has been disabled by default since PHP 4.2.0 You should therefore use $_SESSION['var'] instead.
