|
Writes the session data to the session storage. Called by normal PHP shutdown, by
|
|
<function>session_write_close</function>, or when <function>session_register_shutdown</function> fails.
|
|
PHP will call <function>SessionHandler::close</function> immediately after this method returns.
|
|
</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 inheritiance, calling the parent <parameter>write</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 (for example, encrypting the <parameter>$data</parameter> value
|
|
before sending it to the parent <parameter>write</parameter> method).

For more information on what this method is expected to do, please refer to the documentation
|
|
at <function>SessionHandlerInterface::write</function>.
