Vanilla Forums: how to support multiple configuration options depending on the server/hostname/etc.

bootstrap.before.php

<?php

// Detect any specific server environment config setup to apply
// I use a custom variable where you can set like so in Apache VirtualHost or in .htaccess:
//   `SetEnv HTTP_SERVER_ENVIRONMENT "staging"
// Default: development
$server_environment = 'development';
if ( ! empty( $_SERVER['HTTP_SERVER_ENVIRONMENT'] ) ) {
  $server_environment = $_SERVER['HTTP_SERVER_ENVIRONMENT'];
}

// Load the server environment config, only if a corresponding file exists
$env_config_path = PATH_CONF . '/config-' . $server_environment . '.php';
if ( ! empty( $_SERVER['HTTP_SERVER_ENVIRONMENT'] ) && file_exists( $env_config_path ) ) {
  Gdn::Config()->Load( $env_config_path, 'Configuration', TRUE );
}
