Env

This simple package helps you get environment variables with getenv.

Installation

composer require arcesilas/env

Usage

use Arcesilas\Env\Env;

$debug = Env::get('DEBUG');
$dsn = Env::get('DSN', 'sqlite:memory:'); // Returns the DSN env value, "sqlite:memory:" if not set

You may prefer to use the function helper:

$debug = env('DEBUG');
$dsn = env('DSN', 'sqlite:memory:');

Default values

When an environment variable is not set, null is returned by default. You can specify a default value as the second argument.

The default value may be a Closure:

$foo = env('foo', function () {
    return 42;
});

The Closure will be executed and its result will be returned.

Types conversion

Some values are automatically converted to their native PHP equivalent type:

• integers
• floats
• booleans
• null

Booleans can be converted from the following (case insensitive) strings:

• "true", "on", "yes" => true
• "false", "off", "no" => false
