Symfony 4 Fundamentals: Services, Config & Environments Tutorial

NOTE

AdapterInterface

get data from cache:

$item = $adapter→getItem('markdown_'.md5($articleContent));
$item→get() : return data.

Save data to cache:

$item->set($markdown->transform($articleContent)); $adapter->save($item);

Change cache.yaml

enabled cache.adapter.apcu config .env :APP_ENV=prod => cache no rebuild

Create service

create folder container [Services] create class [service] have __construct create function

working LoggerInterface:

Register with create file log

add code before block main in file dev/monolog.yaml

markdown_loggin: 
    type: stream path: "%kernel.logs_dir%/markdown.log" l
    level: debug 
    channels: ["markdown"]

create monolog.yaml and paste code

monolog: 
    channels: ['markdown'

register with services.yaml

1

App\services\MarkDownHelper:
    arguments:
	    $logger: '@monolog.logger.markdown'

other #2: using bind block _defaults:

bind: 
    $markdownLogger: '@monolog.logger.markdown'

important:

file [service] change LoggerInterface variable to  $markdownLogger

Parameter in yaml file

parameters: 
    cache_adapter: 'cache.adapter.apcu'

using ‘%cache_adapter%’

Bind no working controller

https://symfonycasts.com/screencast/symfony-fundamentals/controller-constructor#play

in video, it’s work through __contruct() . But now it’s working good.!!!

Env global

Yaml file using %env(name)% Php file using $_SERVER[‘name’])

LoggerTrait & Setter Injection

/** * @var LoggerInterface | null */ 
private $logger;
/** 
* @required
*/ 
public function setLogger(LoggerInterface $logger){ 
    $this->logger = $logger; 
}

Fun with Commands

$input → getArgument(‘name’);
