<para>
Create new session, or re-initialize existing session. Called internally by PHP when
a session starts either automatically or when <function>session_start</function> is invoked.
</para>
<para>
This method wraps the internal PHP save handler defined in the
<link linkend="ini.session.save-handler">session.save_handler</link> ini setting that was set
before this handler was set by <function>session_set_save_handler</function>.
</para>
<para>
If this class is extended by inheritance, calling the parent <parameter>open</parameter> method will invoke the
wrapper for this method and therefore invoke the associated internal callback. This allows this method to be
overridden and or intercepted and filtered.
</para>
<para>
For more information on what this method is expected to do, please refer to the documentation at
<function>SessionHandlerInterface::open</function>.
