|
* DotArray holds a multi-dimensional array and wraps the static API of `\nochso\Omni\Dot`. |
6
|
|
|
* |
7
|
|
|
* e.g. |
8
|
|
|
* ```php |
9
|
|
|
* $array = [ |
10
|
|
|
* 'a' => [ |
11
|
|
|
* 'b' => 'c' |
12
|
|
|
* ] |
13
|
|
|
* ]; |
14
|
|
|
* $da = new DotArray(); |
15
|
|
|
* echo $da->get('a.b'); // 'c' |
16
|
|
|
* ``` |
17
|
|
|
* |
18
|
|
|
* ArrayAccess is also possible: |
19
|
|
|
* ```php |
20
|
|
|
* $da['a.b'] = 'c'; |
21
|
|
|
* ``` |
22
|
|
|
* |
23
|
|
|
* You can also escape parts of the path: |
24
|
|
|
* ```php |
25
|
|
|
* $da['a\.b'] === $da->getArray()['a.b'] // true |
26
|
|
|
* ``` |
