/** |

|
|
|
* Normalizes host definitions in the package's Redis Sentinel connection |
|
10
|
|
|
* configuration by splitting host definitions that contain multiple hosts |
|
11
|
|
|
* into individual host definitions to support environment-based configuration. |
|
12
|
|
|
* |
|
13
|
|
|
* The package allows developers to specify multiple hosts in a single Redis |
|
14
|
|
|
* Sentinel "*_HOST" environment variable to provide a way for developers to |
|
15
|
|
|
* configure multiple hosts for a connection through the environment without |
|
16
|
|
|
* the need to modify the package's default configuration. An environment |
|
17
|
|
|
* variable can contain a comma-seperated string of hosts that the package will |
|
18
|
|
|
* split automatically using this class: |
|
19
|
|
|
* |
|
20
|
|
|
* REDIS_HOST=sentinel1.example.com,sentinel2.example.com |
|
21
|
|
|
* |
|
22
|
|
|
* Before parsing the connection configuration, the connection config would |
|
23
|
|
|
* contain the following value if using the environment variable above: |
|
24
|
|
|
* |
|
25
|
|
|
* 'connection' => [ |
|
26
|
|
|
* [ |
|
27
|
|
|
* 'host' => 'sentinel1.example.com,sentinel2.example.com', |
|
28
|
|
|
* 'port' => 26379, |
|
29
|
|
|
* ] |
|
30
|
|
|
* ] |
|
31
|
|
|
* |
|
32
|
|
|
* This class will convert the connection configuration to: |
|
33
|
|
|
* |
|
34
|
|
|
* 'connection' => [ |
|
35
|
|
|

|
36

|

* 'host' => 'sentinel1.example.com', |

|
40
