$url = 'http://example.com/name.jpg';

Yii::$app->push(function () use ($url, $file) {
file_put_contents($file, file_get_contents($url));
});

Converts the closure to a job object
| public void beforePush ( yii\queue\PushEvent $event ) | ||
| $event | yii\queue\PushEvent | |
Declares event handlers for the $owner's events.
Child classes may override this method to declare what PHP callbacks should be attached to the events of the $owner component.
The callbacks will be attached to the $owner's events when the behavior is attached to the owner; and they will be detached from the events when the behavior is detached from the component.
The callbacks can be any of the following:
- method in this behavior:
'handleClick', equivalent to[$this, 'handleClick'] - object method:
[$object, 'handleClick'] - static method:
['Page', 'handleClick'] - anonymous function:
function ($event) { ... }
The following is an example:
[
Model::EVENT_BEFORE_VALIDATE => 'myBeforeValidate',
Model::EVENT_AFTER_VALIDATE => 'myAfterValidate',
]
| public array events ( ) | ||
| return | array | Events (array keys) and the corresponding event handler methods (array values). |
