Drupal Environment

Provides a class for working with Drupal environments and environment variables.

This also standardizes some environment terminology between hosting providers so that you can use the same code across different hosts:

Environment	Acquia	Pantheon
Production	prod	live
Staging	test	test
Development	dev	dev

Basic Usage

Getting an environment variable

use DrupalEnvironment\Environment;
$value = Environment::get('VARIABLE_NAME');

The advantages of using this is the results are statically cached.

Testing for Drupal hosting or CI environments

use DrupalEnvironment\Environment;

// These all return a boolean true/false
Environment::isPantheon();
Environment::isAcquia();
Environment::isTugboat();
Environment::isGitHubWorkflow();
Environment::isGitLabCi();
Environment::isCircleCi();

Testing for specific environments

use DrupalEnvironment\Environment;

// This gets the specific environment string.
$environment = Environment::getEnvironment();

// These all return a boolean true/false
Environment::isProduction();
Environment::isStaging();
Environment::isDevelopment();
Environment::isCi();
Environment::isLocal(); // Covers both DDEV and Lando
Environment::isDdev();
Environment::isLando();

Testing for executable commands

use DrupalEnvironment\Environment;

// This returns a boolean true/false:
Environment::commandExists('composer');

Example usage

settings.php

use DrupalEnvironment\Environment;

if (Environment::isProduction()) {
  // Set some production environment settings overrides.
}
elseif (Environment::isStaging()) {
  // Set some staging environment settings overrides.
}
elseif (Environment::isDevelopment()) {
  // Set some development environment settings overrides.
}
elseif (Environment::isLocal()) {
  // Set some development environment settings overrides.
}

// Include a environment-specific settings file.
if ($environment = Environment::getEnvironment()) {
  $settings_file = 'settings.' . $environment . '.php';
  if (is_file($settings_file)) {
    require_once $settings_file;
  }
}
