Php会话变量返回另一个变量

Question

I don't understand the next declaration:

$_SESSION['lang'] = 'LANG VARIABLE';
$_SESSION['lang_vars'] = 'LANG VARS';

echo $_SESSION['lang']; // Return text "LANG VARIABLE"
$lang = $_SESSION['lang_vars'];
echo $_SESSION['lang']; // Return text "LANG VARS"
exit();

On my wamp server there is no error like this, but up on server i Got this...

There must be as php.ini setting that I don't know or what ?

Answer 1

I bet the register_globals option is enabled on the server. You can check this with phpinfo().

Create a .htaccess file with the following content and place it in the root www folder on the server:

php_flag register_globals 0
