__call() public method

Defined in: yii\base\Component::__call()

Calls the named method which is not a class method.

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.

public mixed __call ( $name, $params )
$name string

The method name

$params array

Method parameters

return mixed

The method return value

throws yii\base\UnknownMethodException

when calling unknown method

                public function __call($name, $params)
{
    $this->ensureBehaviors();
    foreach ($this->_behaviors as $object) {
        if ($object->hasMethod($name)) {
            return call_user_func_array([$object, $name], $params);
        }
    }
    throw new UnknownMethodException('Calling unknown method: ' . get_class($this) . "::$name()");
}

            
__clone() public method

Defined in: yii\base\Component::__clone()

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

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

public void __clone ( )

                public function __clone()
{
    $this->_events = [];
    $this->_eventWildcards = [];
    $this->_behaviors = null;
}

            
__construct() public method

Defined in: yii\base\BaseObject::__construct()

Constructor.

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.
public void __construct ( $config = [] )
$config array

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

                public function __construct($config = [])
{
    if (!empty($config)) {
        Yii::configure($this, $config);
    }
    $this->init();
}

            
__get() public method

Defined in: yii\base\Component::__get()

Returns the value of a component property.

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;.

See also __set().

public mixed __get ( $name )
$name string

The property name

return mixed

The property value or the value of a behavior's property

throws yii\base\UnknownPropertyException

if the property is not defined

throws yii\base\InvalidCallException

if the property is write-only.

                public function __get($name)
{
    $getter = 'get' . $name;
    if (method_exists($this, $getter)) {
        // read property, e.g. getName()
        return $this->$getter();
    }
    // behavior property
    $this->ensureBehaviors();
    foreach ($this->_behaviors as $behavior) {
        if ($behavior->canGetProperty($name)) {
            return $behavior->$name;
        }
    }
    if (method_exists($this, 'set' . $name)) {

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).

See also https://www.php.net/manual/en/function.isset.php.

public boolean __isset ( $name )
$name string

The property name or the event name

return boolean

Whether the named property is set

    }
    return false;
}

            
__set() public method

Defined in: yii\base\Component::__set()

}

            
asCurrency() public method

Defined in: yii\i18n\Formatter::asCurrency()

Formats the value as a currency number.

This function does not require the PHP intl extension to be installed to work, but it is highly recommended to install it to get good formatting results.

Since 2.0.16 numbers that are mispresented after normalization are formatted as strings using fallback function without PHP intl extension support. For very big numbers it's recommended to pass them as strings and not use scientific notation otherwise the output might be wrong.

public string asCurrency ( $value, $currency null, $options = [], $textOptions = [] )
$value mixed

The value to be formatted.

$currency string|null

The 3-letter ISO 4217 currency code indicating the currency to use. If null, $currencyCode will be used.

$options array

Optional configuration for the number formatter. This parameter will be merged with $numberFormatterOptions.

$textOptions array

Optional configuration for the number formatter. This parameter will be merged with $numberFormatterTextOptions.

return string

The formatted result.

throws yii\base\InvalidArgumentException

if the input value is not numeric or the formatting failed.

throws yii\base\InvalidConfigException

}

            
asDate() public method

Defined in: yii\i18n\Formatter::asDate()

Formats the value as a date.

See also $dateFormat.

public string asDate ( $value, $format null )
$value integer|string|DateTime|DateTimeInterface|null

The value to be formatted. The following types of value are supported:

  • an integer representing a UNIX timestamp. A UNIX timestamp is always in UTC by its definition.
  • a string that can be parsed to create a DateTime object. The timestamp is assumed to be in $defaultTimeZone unless a time zone is explicitly given.
  • a PHP DateTime object. You may set the time zone for the DateTime object to specify the source time zone.

The formatter will convert date values according to $timeZone before formatting it. If no timezone conversion should be performed, you need to set $defaultTimeZone and $timeZone to the same value. Also no conversion will be performed on values that have no time information, e.g. "2017-06-05".

$format string|null

The format used to convert the value into a date string. If null, $dateFormat will be used.

This can be "short", "medium", "long", or "full", which represents a preset format of different lengths. It can also be a custom format as specified in the ICU manual.

Alternatively this can be a string prefixed with php: representing a format that can be recognized by the PHP date()-function.

return string

The formatted result.

throws yii\base\InvalidArgumentException

if the input value can not be evaluated as a date value.

throws yii\base\InvalidConfigException

if the date format is invalid.

asDecimal() public method

Defined in: yii\i18n\Formatter::asDecimal()

Formats the value as a decimal number.

Property $decimalSeparator will be used to represent the decimal point. The value is rounded automatically to the defined decimal digits.

Since 2.0.16 numbers that are mispresented after normalization are formatted as strings using fallback function without PHP intl extension support. For very big numbers it's recommended to pass them as strings and not use scientific notation otherwise the output might be wrong.

See also:

public string asDecimal ( $value, $decimals null, $options = [], $textOptions = [] )
$value mixed

The value to be formatted.

$decimals integer|null

The number of digits after the decimal point. If not given, the number of digits depends in the input value and is determined based on NumberFormatter::MIN_FRACTION_DIGITS and NumberFormatter::MAX_FRACTION_DIGITS, which can be configured using $numberFormatterOptions. If the PHP intl extension is not available, the default value is 2. If you want consistent behavior between environments where intl is available and not, you should explicitly specify a value here.

The value to be formatted. The following types of value are supported:

  • an integer representing a UNIX timestamp. A UNIX timestamp is always in UTC by its definition.
  • a string that can be parsed to create a DateTime object. The timestamp is assumed to be in $defaultTimeZone unless a time zone is explicitly given.
  • a PHP DateTime object. You may set the time zone for the DateTime object to specify the source time zone.

The formatter will convert date values according to $timeZone before formatting it. If no timezone conversion should be performed, you need to set $defaultTimeZone and $timeZone to the same value.

$format string|null

The format used to convert the value into a date string. If null, $timeFormat will be used.

This can be "short", "medium", "long", or "full", which represents a preset format of different lengths. It can also be a custom format as specified in the ICU manual.

Alternatively this can be a string prefixed with php: representing a format that can be recognized by the PHP date()-function.

Note that a behavior class must extend from yii\base\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).

format() public method

Defined in: yii\i18n\Formatter::format()

Formats the value based on the given format type.

This method will call one of the "as" methods available in this class to do the formatting. For type "xyz", the method "asXyz" will be used. For example, if the format is "html", then asHtml() will be used. Format names are case insensitive.

public string format ( $value, $format )
$value mixed

The value to be formatted.

$format string|array|Closure

The format of the value, e.g., "html", "text" or an anonymous function returning the formatted value.

To specify additional parameters of the formatting method, you may use an array. The first element of the array specifies the format name, while the rest of the elements will be used as the parameters to the formatting method. For example, a format of ['date', 'Y-m-d'] will cause the invocation of asDate($value, 'Y-m-d').

The anonymous function signature should be: function($value, $formatter), where $value is the value that should be formatted and $formatter is an instance of the Formatter class, which can be used to call other formatting functions. The possibility to use an anonymous function is available since version 2.0.13.

return string

off() public method

Defined in: yii\base\Component::off()

Detaches an existing event handler from this component.

This method is the opposite of on().

Note: in case wildcard pattern is passed for event name, only the handlers registered with this wildcard will be removed, while handlers registered with plain names matching this wildcard will remain.

See also on().

public boolean off ( $name, $handler null )
$name string

Event name

$handler callable|null

The event handler to be removed. If it is null, all handlers attached to the named event will be removed.

return boolean

If a handler is found and detached

                public function off($name, $handler = null)
{
    $this->ensureBehaviors();
    if (empty($this->_events[$name]) && empty($this->_eventWildcards[$name])) {
        return false;
    }
    if ($handler === null) {
        unset($this->_events[$name], $this->_eventWildcards[$name]);
        return true;
    }
    $removed = false;
    // plain event names
    if (isset($this->_events[$name])) {
        foreach ($this->_events[$name] as $i => $event) {
            if ($event[0] === $handler) {
                unset($this->_events[$name][$i]);
                $removed = true;
            }

}

            
on() public method

Defined in: yii\base\Component::on()

Attaches an event handler to an event.

The event handler must be a valid PHP callback. The following are some examples:

function ($event) { ... }         // anonymous function
[$object, 'handleClick']          // $object->handleClick()
['Page', 'handleClick']           // Page::handleClick()
'handleClick'                     // global function handleClick()

The event handler must be defined with the following signature,

function ($event)

where $event is an yii\base\Event object which includes parameters associated with the event.

Since 2.0.14 you can specify event name as a wildcard pattern:

$component->on('event.group.*', function ($event) {
    Yii::trace($event->name . ' is triggered.');
});

See also off().

public void on ( $name, $handler, $data null, $append true )
$name string

The event name

$handler callable

The event handler

$data mixed

The data to be passed to the event handler when the event is triggered. When the event handler is invoked, this data can be accessed via yii\base\Event::$data.

$append boolean

Whether to append new event handler to the end of the existing handler list. If false, the new handler will be inserted at the beginning of the existing handler list.

                public function on($name, $handler, $data = null, $append = true)
{
    $this->ensureBehaviors();
    if (strpos($name, '*') !== false) {
        if ($append || empty($this->_eventWildcards[$name])) {
            $this->_eventWildcards[$name][] = [$handler, $data];
        } else {
            array_unshift($this->_eventWildcards[$name], [$handler, $data]);
        }
        return;
    }
    if ($append || empty($this->_events[$name])) {
        $this->_events[$name][] = [$handler, $data];
    } else {
        array_unshift($this->_events[$name], [$handler, $data]);
    }
}

            
trigger() public method

Defined in: yii\base\Component::trigger()

Triggers an event.

This method represents the happening of an event. It invokes all attached handlers for the event including class-level handlers.

public void trigger ( $name, yii\base\Event $event null )
$name string

The event name

$event yii\base\Event|null

The event instance. If not set, a default yii\base\Event object will be created.

                public function trigger($name, Event $event = null)
{
    $this->ensureBehaviors();
    $eventHandlers = [];
    foreach ($this->_eventWildcards as $wildcard => $handlers) {
        if (StringHelper::matchWildcard($wildcard, $name)) {
            $eventHandlers[] = $handlers;
        }
    }
    if (!empty($this->_events[$name])) {
        $eventHandlers[] = $this->_events[$name];
    }
    if (!empty($eventHandlers)) {
        $eventHandlers = call_user_func_array('array_merge', $eventHandlers);
        if ($event === null) {
            $event = new Event();
        }
        if ($event->sender === null) {
            $event->sender = $this;
        }
        $event->handled = false;
        $event->name = $name;
        foreach ($eventHandlers as $handler) {
            $event->data = $handler[1];
            call_user_func($handler[0], $event);
            // stop further handling if the event is handled
            if ($event->handled) {
                return;
            }
        }
    }
    // invoke class-level attached handlers
    Event::trigger($this, $name, $event);
}
