README
A component that allows easy object configuration with default and overriding settings
Latest release API documentation: https://aloframework.github.io/config/
Installation
Installation is available via Composer:
composer require aloframework/config
The abstract class
AloFramework\Config\AbstractConfig
is what your own library configurations should extend. It has three main private properties: $defaults
holding default configuration, $custom
holding custom configuration/overrides and $merged
, which holds the actual configuration that will be used. Your overriding config class will populate the default array and accept any custom variables in the constructor, e.g.:
use AloFramework\Config\AbstractConfig;
class MyConfig extends AbstractConfig {
private static $defaultConfig = ['foo' => 'bar',
'importantVar' => 'andItsValue'];
function __construct($customConfig = []) {
parent::__construct(self::$defaultConfig, $customConfig);
}
}
When reading the configuration, the values are fetched from the $merged
array, which is essentially an array_merge($this->defaults, $this->custom)
. For more information refer to the API documentation above.
The interface
You can implement the AloFramework\Config\Configurable
interface in your configuration-reading class to indicate that its runtime settings can be altered using this package. The trait described below can be used to implement the required methods.
The trait
If you don't want to write your own methods you can simply include the provided AloFramework\Config\ConfigurableTrait
which will implement all the methods required by the interface.
Updating the configuration
Setting an item
You can add a custom configuration key or default setting override by calling $config->set('myKey', 'myValue')
, using __set()
like $config->myKey = 'myValue'
, or simply using it like an array: $config['myKey'] = 'myValue'
.
Removing an item
You can remove custom configuration via $config->remove('myKey')
, or by unsetting it like an array value: unset($config['myKey']);
Reading the configuration
Specific value
You can retrieve a specific configuration item from the merged array by calling $config->get('myKey')
, using __get()
like $config->myKey
or by using the object like an array: $config['myKey']
.
The merged config
You can retrieve the merged array via $config->getAll()
The default config
For this you would use $config->getDefaultConfig()
The custom overrides
For this you would use $config->getCustomConfig()
.
