CConfiguration represents an array-based configuration.

It can be used to initialize an object's properties.

The configuration data may be obtained from a PHP script. For example,

<?php
return array
(
    'name'=>'My Application',
    'defaultController'=>'index',
);
?>

Use the following code to load the above configuration data:

$config=new CConfiguration('path/to/config.php');

To apply the configuration to an object, call applyTo(). Each (key,value) pair in the configuration data is applied to the object like: $object->$key=$value.

Since CConfiguration extends from CMap, it can be used like an associative array. See CMap for more details.

Method Details

__construct() method

public void __construct(mixed $data=NULL)
$data	mixed	if string, it represents a config file (a PHP script returning the configuration as an array); If array, it is config data.

Constructor.

applyTo() method

public void applyTo(object $object)
$object	object	object to be applied with this configuration

Applies the configuration to an object. Each (key,value) pair in the configuration data is applied to the object like: $object->$key=$value.

createObject() method

public static mixed createObject(mixed $config)
$config	mixed	the configuration. It can be either a string or an array.
{return}	mixed	the created object

Creates an object and initializes it based on the given configuration.

NOTE: this method has been deprecated since version 1.0.1. Please use Yii::createComponent, instead.

loadFromFile() method

public void loadFromFile(string $configFile)
$configFile	string	configuration file path (if using relative path, be aware of what is the current path)

Loads configuration data from a file and merges it with the existing configuration.

A config file must be a PHP script returning a configuration array (like the following)

return array
(
    'name'=>'My Application',
    'defaultController'=>'index',
);
