Class variables
- $dsn
- type:
- string
- description:
- DSN
- detail:
- selected by default DSN
- example:
$dsn = ‘gree(memcache)://node/user’
- $driver_type
- type:
- int
- description:
- identifier of connection driver
- detail:
- Specify the driver userd to query the databse to KVS. See also to class constant below.
- example:
$driver_type = self::DRIVER_LIBMEMCACHED
- $namespace
- type:
- string
- description:
- namespace
- detail:
- Namespace is used as a prefix to avoid conflicts for key. For example, $namespace = ‘foo’, $key = ‘bar’ as it is actually stored in ‘foo#bar’. The use of namespaces, allowing coexistence of multiple DataFormat in same KVS server.
- example:
-
- $compressed
- type:
- boolean
- description:
- flag of compression
- detail:
- If you want to disable compression, set this flag to false. When using ‘increment’ or ‘decrement’, you must set to false.
- example:
