the current session is changed to its value.

The session name references the session id in cookies and
|
|
URLs. It should contain only alphanumeric characters; it should
|
|
be short and descriptive (i.e. for users with enabled cookie
|
|
warnings). The session name is reset to the default value
|
|
stored in <literal>session.name</literal> at request startup
|
|
time. Thus, you need to call <function>session_name</function>
|
|
for every request (and before <function>session_start</function>
|
|
or <function>session_register</function> are called).
