Methods
__construct(array $config = array()) : void
Constructor.
$config is an array of key/value pairs containing configuration
options. Note that the SQLite options are different than most of
the other PDO adapters in that no username or password are needed.
Also, an extra config key "sqlite2" specifies compatibility mode.
dbname => (string) The name of the database to user (required,
use :memory: for memory-based database)
sqlite2 => (boolean) PDO_SQLITE defaults to SQLite 3. For compatibility
with an older SQLite 2 database, set this to TRUE.
ParametersName | Type | Description |
---|---|---|
$config | array | An array of configuration keys. |
_checkRequiredOptions(array $config) : void
Check for config options that are mandatory.
Throw exceptions if any are missing.
