If register_globals is disabled, only elements of the global array $ _SESSION contain variables recorded in the session. The restored session variables will only be available in $ _SESSION. You should keep in mind that $ _SESSION is available as a global variable just like $ _POST, $ _GET, $ _REQUEST, etc. Therefore, you do not need to use the reserved word global with $ _SESSION. The array keys $ _SESSION are subject to the same limitations as regular variable names in PHP. For example, you cannot start with a number, but start with a letter or underscore '_'.

If register_globals is disabled, only elements of the global array $ _SESSION contain variables recorded in the session. The restored session variables will only be available in $ _SESSION. Use of $ _SESSION is recommended for improved security and code readability. With $ _SESSION, there is no need to use functions session_register (), session_unregister () and session_is_registered ().Session variables are accessible like any other variable.

I am providing you with the coding that will help you to register a variable with $ _SESSION. So , just have a look at the sample of coding :

PHP Code:

<?php 
session_start (); 
if (!isset( $_SESSION [ 'count' ])) { 
$_SESSION [ 'count' ] = 0 ; 
} else { 
$_SESSION [ 'count' ]++; 
} 
?>

If register_globals is enabled, then each global variable can be registered as session variables, and all session variables will be reconstructed as global variables. Since PHP must know which global variables are registered as session variables, users need to register variables with session_register () while $ HTTP_SESSION_VARS and $ _SESSION does not require session_register (). You can remove a variable with $ _SESSION and register_globals disabled by using the following code :

PHP Code:

<?php 
session_start (); 
unset( $_SESSION [ 'count' ]); 
?>
