* @return string the Data Source Name, or DSN, contains the information required to connect to the database. |
|
26
|
|
|
* Please refer to the [PHP manual](http://php.net/manual/en/pdo.construct.php) on the format of the DSN string. |
|
27
|
|
|
* |
|
28
|
|
|
* The `driver` array key is used as the driver prefix of the DSN, all further key-value pairs are rendered as |
|
29
|
|
|
* `key=value` and concatenated by `;`. For example: |
|
30
|
|
|
* |
|
31
|
|
|
* ```php |
|
32
|
|
|
* $dsn = new Dsn('mysql', '127.0.0.1', 'yiitest', '3306'); |
|
33
|
|
|
* $connection = new Connection($this->cache, $this->logger, $this->profiler, $dsn->asString()); |
|
34
|
|
|
* ``` |
|
35
|
|
|
* |
|
36
|
|
|
* With autowired container-di: |
|
37
|
|
|
* |
|
38
|
|
|
* ```php |
|
39
|
|
|
* $dsn = new Dsn('mysql', '127.0.0.1', 'yiitest', '3306'); |
|
40
|
|
|
* $connection = new Connection('dsn' => $dsn->asString()); |
|
41
|
|
|
* ``` |
|
42
|
|
|
* |
|
43
|
|
|
* Will result in the DSN string `mysql:host=127.0.0.1;dbname=yiitest;port=3306`. |
