Dotenv

What is it?

Small library, that automaticaly loads .env (or any other) file to applications environment.

Why not XXX?

Because this library is pretty simple, without external dependencies and highly customizable.

Installation

composer require neonxp/dotenv

Usage

Basic usage:

use NeonXP\Dotenv\Dotenv;

$dotenv = new Dotenv();
$dotenv->load(); // You can specify file to load at first argument

print $dotenv->get('KEY', 'default') . PHP_EOL;
print $dotenv['KEY'] . PHP_EOL;
foreach ($dotenv as $key => $value) {
    print "$key = $value" . PHP_EOL;
}

.env file syntax

Here examples of syntax:

# This is a comment

# Empty lines also ignored
export KEY1=VALUE1
KEY2 = VALUE2 # Inline comment
KEY3 = 'VALUE3 # This is not comment'
KEY4 = "VALUE4 # And this value too"
KEY5 = ${KEY1} -> ${KEY2} # Compilled from another variables

and we will get:

[
    'KEY1' => 'VALUE1',
    'KEY2' => 'VALUE2',
    'KEY3' => 'VALUE3 # This is not comment',
    'KEY4' => 'VALUE4 # And this value too',
    'KEY5' => 'VALUE1 -> VALUE2',
]
