Methods

__call()

Calls the named method which is not a class method.

public __call(string $name, array<string|int, mixed> $params) : mixed

This method will check if any attached behavior has the named method and will execute it if available.

Do not call this method directly as it is a PHP magic method that will be implicitly called when an unknown method is being invoked.

Parameters
$name : string

the method name

$params : array<string|int, mixed>

method parameters

Tags
throws
UnknownMethodException

when calling unknown method

Return values
mixed —

__clone()

This method is called after the object is created by cloning an existing one.

public __clone() : mixed

It removes all behaviors because they are attached to the old object.

__construct()

Constructor.

public __construct([array<string|int, mixed> $config = [] ]) : mixed

The default implementation does two things:

  • Initializes the object with the given configuration $config.
  • Call [[init()]].

If this method is overridden in a child class, it is recommended that

  • the last parameter of the constructor is a configuration array, like $config here.
  • call the parent implementation at the end of the constructor.
Parameters
$config : array<string|int, mixed> = []

name-value pairs that will be used to initialize the object properties

__get()

Returns the value of a component property.

public __get(string $name) : mixed

This method will check in the following order and act accordingly:

  • a property defined by a getter: return the getter result
  • a property of a behavior: return the behavior property value

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing $value = $component->property;.

Parameters
$name : string

the property name

Tags
throws
UnknownPropertyException

if the property is not defined

throws
InvalidCallException

if the property is write-only.

see
__set()
Return values
mixed —

__isset()

Checks if a property is set, i.e. defined and not null.

public __isset(string $name) : bool

This method will check in the following order and act accordingly:

  • a property defined by a setter: return whether the property is set
  • a property of a behavior: return whether the property is set
  • return false for non existing properties

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing isset($component->property).

Parameters
$name : string

the property name or the event name

Tags
see
https://www.php.net/manual/en/function.isset.php
Return values
bool —

whether the named property is set

__set()

public __set(string $name, mixed $value) : mixed

This method will check in the following order and act accordingly:

  • a property defined by a setter: set the property value
  • an event in the format of "on xyz": attach the handler to the event "xyz"
  • a behavior in the format of "as xyz": attach the behavior named as "xyz"
  • a property of a behavior: set the behavior property value

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing $component->property = $value;.

Parameters
$name : string

the property name or the event name

$value : mixed

the property value

Tags
throws
UnknownPropertyException

if the property is not defined

throws
InvalidCallException

if the property is read-only.

attachBehavior()

Attaches a behavior to this component.

public attachBehavior(string $name, string|array<string|int, mixed>|Behavior $behavior) : Behavior

$requests = [
    'news' => $client->get('http://domain.com/news'),
    'friends' => $client->get('http://domain.com/user/friends', ['userId' => 12]),

behaviors()

Returns a list of behaviors that this component should behave as.

public behaviors() : array<string|int, mixed>

Child classes may override this method to specify the behaviors they want to behave as.

The return value of this method should be an array of behavior objects or configurations indexed by behavior names. A behavior configuration can be either a string specifying the behavior class or an array of the following structure:

'behaviorName' => [
    'class' => 'BehaviorClass',
    'property1' => 'value1',
    'property2' => 'value2',
]

Note that a behavior class must extend from [[Behavior]]. Behaviors can be attached using a name or anonymously. When a name is used as the array key, using this name, the behavior can later be retrieved using [[getBehavior()]] or be detached using [[detachBehavior()]]. Anonymous behaviors can not be retrieved or detached.

Behaviors declared in this method will be attached to the component automatically (on demand).

Return values
array<string|int, mixed> —

the behavior configurations.

Parameters
$name : string
