16 * From http://www.php.net/manual/en/language.oop.serialization.php:
17 * In case this isn't clear:
91e0dccc 18 * In 4.2 and below:
de702cb8 19 * session.auto_start and session objects are mutually exclusive.
20 *
91e0dccc 21 * We need to load the classes before the session is started,
22 * except that the session could be started automatically
23 * via session.auto_start. So, we'll close the session,
24 * then load the classes, and reopen the session which should
25 * make everything happy.
de702cb8 26 *
27 * ** Note this means that for the 1.3.2 release, we should probably
28 * recommend that people set session.auto_start=0 to avoid this altogether.
