<h2>Removing Session Data</h2>
<p>Just as set_userdata() can be used to add information into a session, unset_userdata() can be used to remove it, by passing the session key. For example, if you wanted to remove 'some_name' from your session information: </p>
<p><code>$this-&gt;session-&gt;unset_userdata('some_name');</code></p>
