* SessionHandlerInterface for PHP < 5.4.

* The order in which these methods are invoked by PHP are:
* 1. open [session_start]
* 2. read
* 3. gc [optional depending on probability settings: gc_probability / gc_divisor]
* 4. destroy [optional when session_regenerate_id(true) is used]
* 5. write [session_write_close] or destroy [session_destroy]
* 6. close
*
