What you need to use is session_id() instead of session_name()

", print_r($_SESSION, 1), "

"; session_write_close(); session_id("session2"); echo session_id(); session_start(); $_SESSION["name"] = "2"; echo "

", print_r($_SESSION, 1), "

"; session_write_close(); session_id("session1"); echo session_id(); session_start(); echo "

", print_r($_SESSION, 1), "

"; session_write_close(); session_id("session2"); echo session_id(); session_start(); echo "

", print_r($_SESSION, 1), "

";

This will print:

session1

Array
(
    [name] => 1
)

session2

Array
(
    [name] => 2
)

session1

Array
(
    [name] => 1
)

session2

Array
(
    [name] => 2
)

session_id is an identifier for a session, which helps in distinguishing sessions. session_name is only a named alias for the current session
