question in sessions and array

i have session code

it's working fine

but some friend told me this code should not work !

but it's work fine with me !

i try code on localhost

so my question is , if i uploaded this code to my server

it will work fine like localhost ?

or will not work like my friend said ?

my code is

session_start();
$_SESSION['news'][] = 'First';
$_SESSION['news'开发者_JAVA技巧][] = 'Second';
print_r($_SESSION['news']);

its print Array ( [0] => First [1] => Second )

and that's what i want ! it's fine ..

Yes it will work definitely. Or to be more safe you can do like following before assigning it values.

    $_SESSION['news'] = array();

Your friend is wrong. You can use arrays as session variables.

For supporting arguments, please see array as session variable and Can I Store An Array In A Session?.

It seems okay to me. There's no reason why it shouldn't work on your server.
