Phalcon\Config is a component used to convert configuration files of various formats (using adapters) into PHP objects for use in an application.
Values can be obtained from Phalcon\Config as follows:
Loads Config Adapter class using adapter option, if no extension is provided it will be added to filePath
The first example shows how to convert native arrays into Phalcon\Config objects. This option offers the best performance since no files are read during this request.
If you want to better organize your project you can save the array in another file and then read it.
The adapters available are:Class / Description
Phalcon\Config\Adapter\Ini / Uses INI files to store settings. Internally the adapter uses the PHP function parse_ini_file.
Phalcon\Config\Adapter\Json / Uses JSON files to store settings.
Phalcon\Config\Adapter\Php / Uses PHP multidimensional arrays to store settings. This adapter offers the best performance.
Phalcon\Config\Adapter\Yaml / Uses YAML files to store settings.
Reading INI Files
Ini files are a common way to store settings. Phalcon\Config uses the optimized PHP function parse_ini_file to read these files. Files sections are parsed into sub-settings for easy access.
You can read the file as follows:
Phalcon\Config can recursively merge the properties of one configuration object into another. New properties are added and existing properties are updated.
The above code produces the following:
There are more adapters available for this components in the Phalcon Incubator
You may easily access nested configuration values using the Phalcon\Config::path method. This method allows to obtain values, without caring about the fact that some parts of the path are absent. Let’s look at an example:
The following example shows how to create usefull facade to access nested configuration values:
Injecting Configuration Dependency
You can inject your configuration to the controller allowing us to use Phalcon\Config inside Phalcon\Mvc\Controller. To be able to do that, you have to add it as a service in the Dependency Injector container. Add following code inside your bootstrap file:
Now in your controller you can access your configuration by using dependency injection feature using name config like following code:
