|
|
* We are not crazy enough - let's work with Windows Registry! In PHP. |
|
20
|
|
|
* - the path is tree and there is bunch of keys; it's composed primary key - part (HK*_*) and path |
|
21
|
|
|
* - the difference with registry and normal file is simple - there is also content type, not just path and content |
|
22
|
|
|
* -> it's similar to flags in *nix or app rights in OS9 |
|
23
|
|
|
* |
|
24
|
|
|
* The registry is hybrid between usual database and filesystem - storing values in tree nodes like FS and with type |
|
25
|
|
|
* control like DB. That means there is specific query set. |
|
26
|
|
|
* This class uses external library added into php which allows most of operations over registry. |
|
27
|
|
|
* |
|
28
|
|
|
* @codeCoverageIgnore cannot check this on *nix |
