PHP Dotenv

.env file parsing for PHP

Requirements

• PHP 5.3+

Installation

[Using Composer]

Add the plugin to your project's composer.json - something like this:

  {
    "require": {
      "josegonzalez/dotenv": "dev-master"
    }
  }

Usage

Create a new loader:

<?php
$Loader = new josegonzalez\Dotenv\Loader('path/to/.env');
// Parse the .env file
$Loader->parse();
// Send the parsed .env file to the $_ENV variable
$Loader->toEnv();
?>

Most methods return the loader directly, so the following is also possible:

<?php
$Loader = (new josegonzalez\Dotenv\Loader('path/to/.env'))
              ->parse()
              ->toEnv(); // Throws LogicException if ->parse() is not called first
?>

Defining Constants

You can also define constants automatically from your env file:

<?php
$Loader = (new josegonzalez\Dotenv\Loader('path/to/.env'))
              ->parse()
              ->define(); // Throws LogicException if ->parse() is not called first
?>

Already defined constants will result in an immediate LogicException.

Adding to $_ENV

<?php
$overwriteENV = true;
$Loader = (new josegonzalez\Dotenv\Loader('path/to/.env'))
              ->parse()
              ->toEnv($overwriteENV); // Throws LogicException if ->parse() is not called first
?>

Already defined $_ENV entries will result in an immediate LogicException, unless $overwriteENV is set to true (default false).

Adding to $_SERVER

<?php
$overwriteSERVER = true;
$Loader = (new josegonzalez\Dotenv\Loader('path/to/.env'))
              ->parse()
              ->toServer($overwriteSERVER); // Throws LogicException if ->parse() is not called first
?>

Already defined $_SERVER entries will result in an immediate LogicException, unless $overwriteSERVER is set to true (default false).

Setting key prefixes

<?php
$environment = (new josegonzalez\Dotenv\Loader('path/to/.env'))
              ->parse()
              ->prefix('FOO')
              ->toServer(); // BAR=baz becomes FOOBAR=baz
?>

Return as array

<?php
$environment = (new josegonzalez\Dotenv\Loader('path/to/.env'))
              ->parse()
              ->toArray(); // Throws LogicException if ->parse() is not called first
?>

Return as json

<?php
$jsonEnvironment = (string)((new josegonzalez\Dotenv\Loader('path/to/.env'))->parse());
?>

Require environment variables

<?php
$Loader = (new josegonzalez\Dotenv\Loader('path/to/.env'))
              ->parse()
              ->expect('FOO', 'BAR', 'BAZ'); // Throws RuntimeException if variables are missing
?>

Turning off exceptions

<?php
$Loader = (new josegonzalez\Dotenv\Loader('path/to/.env'))
              ->parse()
              ->raiseExceptions(false)
              ->expect('FOO', 'BAR', 'BAZ'); // Returns false if variables are missing
?>

Static Environment Definition

You can also call it via the static load method call, which takes an array of arguments. If a method name is specified, the method is called with the value in the $options array being sent into the method.

<?php
josegonzalez\Dotenv\Loader::load(array(
  'filepath' => 'path/to/.env',
  'expect' => array('FOO', 'BAR', 'BAZ'),
  'toEnv' => true,
  'toServer' => true,
  'define' => true,
);
?>
