Introduction

SlimFacades is a package to provide facades for Slim PHP framework.

Facades is a noun from Laravel(also a PHP Framework). Facades provide a "static" interface to classes that are available in the application's service container.

Laravel facades serve as "static proxies" to underlying classes in the service container, providing the benefit of a terse, expressive syntax while maintaining more testability and flexibility than traditional static methods, so does Slim-Facades.

Requirement

• PHP >= 5.5.0
• Slim >= 3.0

Installation

Using composer:
composer require zhangshize/slim-facades

Usage

After the installation, you can update your code like this:

    //... Something not important ...
    use SlimFacades\Facade;
    use SlimFacades\Route;
    use SlimFacades\App;
    
    $app = new \Slim\App(/*...*/);
    // initialize the Facade class
    Facade::setFacadeApplication($app);
    
    Route::get('/', function (Request $req, Response $res) {
        $res->getBody()->write("Hello");
        return $res;
    });
    
    App::run();

Default Facades

The following facades are provided by Slim-Facades:

App

Use it just like using $app!

    App::run();

Container

Use it just like using $container!

    Container::hasService('view');

Route

    Route::get('/', function (Request $req, Response $res) {
        $res->getBody()->write("Hello");
        return $res;
    });

Request

    $method = Request::getMethod();

Response

    Response::withStatus(302);

Setting

There are some special method is the following:

get($key = null)

    /**
     * Get the settings value.
     * If $key = null, this function returns settings.
     * @param string|null $key
     * @return mixed
     */
    public static function get($key = null)
    {
        // ...
    }

Usage

    Settings::get()['db'];
    Settings::get('db');
    //The same result.

set($key, $value)

    /**
     * Set the settings value.
     * When $key is an array, it will be viewed to a list of keys.  <br>
     * For Example:
     * $key = ['a','b']; <br>
     * The function will set the value of $container->settions['a']['b'].
     * @param array|string $key
     * @param mixed $value
     */
    public static function set($key, $value)
    {
        // ...
    }

Usage

    $container['settings']['db']['host'] = 'localhost';
    Settings::set(['db', 'host'], 'localhost');
    //The same result.

View and Log

If you want to use them, you should set 'view' and 'logger' services in the container or change the value which returned by getFacadeAccessor().

Custom Facades

The code for creating a custom facades for a service in the container is the following:

using SlimFacades\Facade;
class CustomFacade extends Facade
{
    protected static function getFacadeAccessor()
    {
        //Change 'serviceName' to you want.
        return 'serviceName';
    }
}

The code for creating a custom facades for an instance is the following:

using SlimFacades\Facade;
class CustomFacade extends Facade
{
    public static function self()
    {
        //Change the returned value to you want.
        return self::$app->getContainer()->get('myservice');
    }
}
