Read, parse and modify environment variables

Installation

You can install this library via composer:

composer require into-the-void/env

Example

use IntoTheVoid\Env\Env;

getenv('APP_DEBUG');   // string(4) "true"
Env::get('APP_DEBUG'); // bool(true)

getenv('DB_PORT');     // string(4) "5432"
Env::get('DB_PORT');   // int(5432)

Env::getString('DB_HOST'); // string(9) "localhost"
Env::getBool('APP_DEBUG'); // bool(true)
Env::getInt('DB_PORT');    // int(5432)
Env::getFloat('APP_MUL');  // double(1.25)
Env::getList('PATH', ':'); // array(2) { "/usr/local/bin", "/usr/bin" }

Env::has('DB_PORT');       // bool(true)
Env::set('DB_PORT', 3306);
Env::remove('DB_PORT');

You may also use the helper function instead of calling Env::get():

use function IntoTheVoid\Env\env;

env('APP_DEBUG'); // bool(true)

Behaviour

Env::getBool('NO_SUCH_VAR');         // NULL
Env::getRequiredBool('NO_SUCH_VAR'); // Fatal error: MissingEnvironmentVariable

Env::getBool('NOT_A_BOOL');                // Fatal error: UnparsableValue
Env::getBool('NOT_A_BOOL', strict: false); // NULL

Repository

By default, environment variables are read via getenv(local_only: true) and getenv(). They are written via putenv(), $_ENV and $_SERVER.

You may change this behaviour using Env::setRepository(). Have a look at src/Repository for available Repositories.

Normalizer

If you want to strip spaces or quotes from your environment variables, then you may configure this via Env::setNormalizer(). Have a look at src/Normalizer for available Normalizers.

This is not done by default, because your environment variables should not contain any unwanted spaces or quotes. If they do you probably should fix the declaration of those environment variables instead.

Parser

Nullish values (case insensitive): '', 'null', 'nil', 'none', 'undefined', 'empty'
Truthy values (case insensitive): '1', 'true', 'y', 'yes', 'on'
Falsy values (case insensitive): '0', 'false', 'n', 'no', 'off'
