Usage

# example .env
FOO=bar
BAR=foo
WHAT=${BAR}-${FOO}

$env = new DotEnv(__DIR__.'/../config', '.env');
$env->load(['foo']); // foo is required

// get a variable
$foo = $_ENV['FOO']; // -> bar
$foo = $env->get('FOO'); // -> bar
$foo = $env->FOO; // -> bar

// dynamically set a variable
$env->set('foo', 'whatever');
$env->FOO = 'whatever';

$foo = $env->get('FOO'); // -> whatever
// ...

// variable substitution
$foo = $env->get('WHAT'); // -> foo-bar

// avoid the global environment
$env = (new DotEnv(__DIR__.'/../config', '.env', false))->load();

$foo = $_ENV['FOO']; // -> undefined
$foo = $env->get('FOO'); // -> bar
$foo = $env->FOO; // -> bar
