Puzzle-configuration 
====================
**_PHP 7.x users please use puzzle/configuration 4.x_**
**_PHP 5.6 users please use puzzle/configuration 3.x_**
Hide configuration implementation behind common interface.
Some advantages :
* Application does not depend upon configuration implementation details
* Application does not have to manage filesystem issues (for filesystem based implementations)
* Application can be easily tested, even for configuration edge cases (missing or wrong configuration values)
* Define configuration as a service in your dependency injection container

Installation
------------
Use composer :
```json
{
"require": {
"puzzle/configuration" : "~4.0"
}
}
```
Documentation
-------------
### Configuration as a service ###
```php
read('app/detection/threshold');
}
}
```
The way the configuration value is read depends on the chosen implementation.
Up to now, 2 implementations are provided :
* Memory (for unit testing purpose)
* Yaml (based on Symfony/Yaml).
For YAML one, ```'app/detection/threshold'``` means ```detection[thresold]``` in app.yml file.
When you instanciate YamlConfiguration object, you need to provide where yaml files can be found :
```php
2
);
$example = new ExampleTest($config);
```
### Default values ###
```php
read('a/b/c', 'default value if a/b/c does not exist');
```
But if ```a/b/c``` is required :
```php
readRequired('a/b/c');
```
### Fallback strategy ###
```php
readFirstExisting('a/b/c', 'd/e/f', 'x/y/z');
```
### Override configuration ###
If you need some configuration to (partially or not) override another one :
```php
overrideBy($defaultConfig)
->overrideBy($localConfig);
// values will be read in localConfig first. They will be read in default config only if they don't exist in local one.
```
Another example :
```php
2
);
$config = new Puzzle\Configuration\Stacked();
$config->overrideBy($defaultConfig)
->overrideBy($overrideConfig);
```
You can add as many as configuration instances you want in the stack. The last inserted is the most prioritary.
If you want to add the least prioritary, use the ```addBase()``` method :
```php
overrideBy($overrideConfig)
->addBase($defaultConfig);
```
### Prefixed configuration ###
You can use automatic prefix decorator ```PrefixedConfiguration```. It can be useful for "namespace like" configurations such as loggers or multiple databases ones.
```yaml
# logger.yml
app:
filename: app.log
verbosity: INFO
users:
filename: users.log
verbosity: WARNING
```
```php
readRequired('filename');
$verbosity = $config->readRequired('verbosity');
```
