* This class implements a provider layer over PDO. |

10

|
|
* |
|
11
|
|
|
* You don't need to use this layer - the framework itself has no dependency on it, but you |
|
12
|
|
|
* may find it useful as a means of addressing certain issues with `PDO`. |
|
13
|
|
|
* |
|
14
|
|
|
* For one, `PDO` instances cannot be created without immediately opening the connection - this |
|
15
|
|
|
* provider does not construct `PDO` and open the connection until you ask for the `PDO` instance. |
|
16
|
|
|
* |
|
17
|
|
|
* Also, `PDO` has no ability to report properties like database-name, username, etc. if you need them. |
