[](#installation)

```
$ composer require chipslays/event
```

Methods
-------

[](#methods)

#### `__construct($data)`

[](#__constructdata)

Parameter `$data` must be a `array`, `json`, `stdClass` or instance of `Chipslays\Collection\Collection`.

#### `on(string $event, callable|string|array $fn [, int $sort = 500]): Event`

[](#onstring-event-callablestringarray-fn--int-sort--500-event)

Paramater `$fn` must be a function or class (support static and non-static methods).

```
$event->on(..., function () {...}, $sort);
$event->on(..., '\App\Controller@method', $sort);
```

Pass any args for `$fn`:

```
$event->on(..., [function ($param1, $param2) {...}, $param1, $param2], $sort);
$event->on(..., ['\App\Controller@method', $param1, $param2], $sort);
```

Pass `$event = true` for force execute event.

```
$event->on(true, ..., ...);
```

Parameter `$sort` responsible for the execution priority.

#### `run(): void`

[](#run-void)

Usage
-----

[](#usage)

```
use Chipslays\Event\Event;

require __DIR__ . 'vendor/autoload.php';

$event = new Event([
    'message' => [
        'text' => 'hello',
    ],
    'user' => [
        'id' => 1234567890,
        'firstname' => 'John',
        'lastname' => 'Doe'
    ],
]);

// Callable function
$event->on('message.text', function () {
    echo 'This event has `text`';
});

// Class
$event->on('message.text', '\App\SomeController@greeting');

$event->run();
```

```
$event->on(['message.text' => 'hello'], function () {
    echo 'Hello 👋';
});
```

```
$event->on(['*.text' => 'hello'], function () {
    echo 'Hello 👋';
});
```

```
// At least one "OR Bye OR Goodbye" logic
$event->on([['message.text' => 'Bye'], ['message.text' => 'Goodbye']], function () {
    echo 'Bye!';
});
```

```
$event->on(['*.text' => 'My name is {name}'], function ($name) {
    echo "Nice to meet you, {$name}!";
});
```

```
// {user} - is a required parameter, he should be in text
// {:time?} - is a optional parameter, it may not be in text
$event->on(['*.text' => '/ban {user} {:time?}'], function ($user = null, $time = null) {
    echo "Banned: {$user}, time:" . $time ?? strtotime('+7 day');
});
```

```
$event->on('{message}', function ($message) {
    echo "Your message: {$message}";
});
```

```
$event->on(['*.text' => '/^hello$/i'], function () {
    echo "Hello!";
});
```

```
// For prevent chain function must return False
$event->on(['*.text' => 'Hi!'], function () {
    echo "Hello!";
    return false;
});

$event->on(['*.firstname' => 'John'], function () {
    echo "This text will never be displayed";
});
```

```
// You can use sort for events
$event->on(['*.firstname' => 'John'], function () {
    echo "This text will never be displayed";
}, 500);

$event->on(['*.text' => 'Hi!'], function () {
    echo "Hello!";
    return false;
}, 400);
```

```
// Pass callback args
$event->on('something', [function ($name, $email) {
    ...
}, 'John', 'test@ema.il']);

$event->on('something', ['SomeController@insert', 'John', 'test@ema.il']);
```

Own Event class
---------------

[](#own-event-class)

You can use events in your class by trait:

```
use Chipslays\Event\EventTrait;

class MyClass
{
    use EventTrait;

    // ...
}
```

Redefine methods `on`, `run`:

```
use Chipslays\Event\EventTrait;

// Redefine methods in other trait
trait MyEventTrait
{
    /**
     * @param array|string $event
     * @param callable|string|array $callback
     * @param integer $sort
     * @return void
     */
    public function on($event, $callback, int $sort = 500)
    {
        // do something before...

        $this->addEvent($event, $callback, $sort);

        // do something after...
    }

    /**
     * @return void
     */
    public function run()
    {
        if ($this->handleEvents()) {
            echo 'At least one event was caught';
        } else {
            echo 'No event was caught';
        }
    }
}

// Create custom class
class MyEventClass
{
    use MyEventTrait, EventTrait {
        MyEventTrait::on insteadof EventTrait;
        MyEventTrait::run insteadof EventTrait;
    }

    // place some methods...
}

$event = new MyEventClass(['message' => ['text' => 'hello']]);

$event->on(['message.text' => 'hello'], function () {
    echo "👋 Hello!";
});

$event->run();
```
