# session_name

(PHP 4 >= 4.0.0)

session_name -- Get and/or set the current session name

## Description

``string session_name` ([string name])`

session_name() returns the name of the current session. If `name` is specified, the name of 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 `session.name` at request startup time. Thus, you need to call session_name() for every request (and before session_start() or session_register() are called).

Example 1. session_name() examples
    <?php

    # set the session name to WebsiteID

    $previous_name = session_name ("WebsiteID");

    echo "The previous session name was $previous_name<p>";
    ?>
