Documentation Fix in PHP Session Handler

Since v3.4.8 of the PHP client library, session.gc_maxlifetime is used to define session TTL in Aerospike Session Handler (it was session.cache_expire in older releases).

Documentation should be fixed:

http://www.aerospike.com/docs/client/php/usage/sessions.html

The value of session.cache_expire session.gc_maxlifetime is the record time-to-live (TTL or expiration).

Thanks for reporting this. We will update our docs.
