extends Kohana_Config_Group
extends ArrayObject

protected string $_group_name

The group this config is for Used when updating config items

protected Kohana_Config $_parent_instance

Reference the config object that created this group Used when updating config


public __construct( Kohana_Config $instance , string $group [, array $config = array(0) ] ) (defined in Kohana_Config_Group)

Constructs the group object. Kohana_Config passes the config group and its config items to the object here.


  • Kohana_Config $instance required - "Owning" instance of Kohana_Config
  • string $group required - The group name
  • array $config = array(0) - Group's config

Source Code

public function __construct(Kohana_Config $instance, $group, array $config = array())
	$this->_parent_instance = $instance;
	$this->_group_name      = $group;

	parent::__construct($config, ArrayObject::ARRAY_AS_PROPS);

public __toString( ) (defined in Kohana_Config_Group)

Return the current group in serialized form.

echo $config;

Return Values

  • string

Source Code

public function __toString()
	return serialize($this->getArrayCopy());

public as_array( ) (defined in Kohana_Config_Group)

Alias for getArrayCopy()

Return Values

  • array - Array copy of the group's config

Source Code

public function as_array()
	return $this->getArrayCopy();

public get( string $key [, mixed $default = NULL ] ) (defined in Kohana_Config_Group)

Get a variable from the configuration or return the default value.

$value = $config->get($key);


  • string $key required - Array key
  • mixed $default = NULL - Default value

Return Values

  • mixed

Source Code

public function get($key, $default = NULL)
	return $this->offsetExists($key) ? $this->offsetGet($key) : $default;

public group_name( ) (defined in Kohana_Config_Group)

Returns the config group's name

Return Values

  • string - The group name

Source Code

public function group_name()
	return $this->_group_name;

public offsetSet( string $key , mixed $value ) (defined in Kohana_Config_Group)

Overrides ArrayObject::offsetSet() This method is called when config is changed via

$config->var = 'asd';

// OR

$config['var'] = 'asd';


  • string $key required - The key of the config item we're changing
  • mixed $value required - The new array value

Source Code

public function offsetSet($key, $value)
	$this->_parent_instance->_write_config($this->_group_name, $key, $value);

	return parent::offsetSet($key, $value);

public set( string $key , mixed $value ) (defined in Kohana_Config_Group)

Sets a value in the configuration array.

$config->set($key, $new_value);


  • string $key required - Array key
  • mixed $value required - Array value

Return Values

  • $this

Source Code

public function set($key, $value)
	$this->offsetSet($key, $value);

	return $this;
