Making Cache, Config, and Env work in harmony (example)

[paxperscientiam]

Hey @mattstauffer ,

This might supersede #192 idea and prior PR. Here is an example of how to get Cache, Config, and Env.

Some notes:

1. Not sure one would want to, but Illuminate\Support\Arr is needed to parse output of Cache::get(...) as it doesn't handle dot notation.
2. I can't beat Laravel's logic for handling cache/env for different environments. Not sure how that would be demonstrated other than copy/pasting from their source code.

Works-for-me example code:

<?PHP

/*
  Note, these variables aren't directly accessible. Use globals
  EG: Illuminate\Support\Facades\Config::get("app.cnx")
 */

use Illuminate\Container\Container;
use Illuminate\Support\Arr;
use Illuminate\Config\Repository;
use Illuminate\Support\Facades\Facade;
use Illuminate\Filesystem\Filesystem;
use Illuminate\Cache\CacheManager;
use Dotenv\Dotenv;
use Illuminate\Support\Facades\Config;
use Illuminate\Support\Facades\Cache;
use Illuminate\Support\Env;

defined("FILE_ROOT") ? true : define("FILE_ROOT", realpath(".."));

// create dummy app
$app = new Container();


// would want to refactor to make sure cache is used in production
try {
    // check if file exists. if not, presume production enviroment
    $dotenv = Dotenv::createImmutable(FILE_ROOT);
    $dotenv->load();
} catch (Exception $e) {
    // presume production
    error_log($e->getMessage());
}

// config setup
$config = new Repository(require(FILE_ROOT . "/backend/config/app.php"));

// bind $config to $app
$app->instance(
    'config',
    $config
);

// cache stuff
$cacheC = new Container();
$cacheC['config'] = $config->get('app.cache');
$cacheC["files"] = new Filesystem();
$cacheManager = new CacheManager($cacheC);
$cache = $cacheManager->store();

// bind $cache to $app
$app->instance(
    'cache',
    $cache
);

$cache->put('test', 'This is loaded from Redis cache.', 500);
$cache->put('app', $config->get('app'));

$config->set('test', 'rofl');

Facade::setFacadeApplication($app);

s(Config::get('test'));
s(Config::get('app.cnx'));

s(Cache::get('test'));
s(Arr::get(Cache::get('app'), 'cnx'));

s(Env::get('RUN_MODE'));

Output:
