in package
implements
jIKVttl, jIKVPersistent
Driver for jKVDB, that uses an SQL table to store key/value data.
Interfaces, Classes and Traits
- jIKVttl
- interface for KV driver which support 'time to live' on values useful to use the driver as a cache storage.
- jIKVPersistent
- interface for KV driver which store values in a persistent manner (in a file...).

- $_driverName : string
- Name of the driver.
- $_profile : array<string|int, mixed>
- Profile for the connection in the kvdb INIfile.
- $_profileName : string
- name of the profile.
- $table : mixed
- __construct() : mixed
- Class constructor.
- __destruct() : mixed
- Class destructor.
- _set() : mixed
- append() : string
- append a string to an existing key value.
- decrement() : int
- decrement a value by $decr. the key should exist and should be an integer.
- delete() : bool
- Deletes a key from the KVdb.
- flush() : bool
- Flush the KVDb. Deletes all keys.
- garbage() : bool
- delete all keys which are not any more valid.
- get() : string
- Gets one or several values;.
- increment() : int
- increment a value by $incr. the key should exist and should be an integer.
- insert() : bool
- Store a key/value. If the key already exist : error.

- prepend a string to an existing key value.
- replace() : bool
- Store a key/value. The key should exists.
- set() : bool
- Store a key/value.
- setWithTtl() : bool
