$_SERVER['DOCUMENT_ROOT'] vs $_ENV['DOCUMENT_ROOT'] in PHP

Question

To set properly the document root when multiple webapps resides under the same websites, according to http://docs.webfaction.com/software/php.html#setting-php-s-document-root we need to:

1- Create a file that will set properly $_SERVER['DOCUMENT_ROOT'] (set_document_root.php)
2- Add the auto_prepend_file directive in php.ini

Question: Do we need also to modify $_ENV['DOCUMENT_ROOT'] ?

The settings are independent. If you also need $_ENV['DOCUMENT_ROOT'], add to the set_document_root.php file like this:

<?php
  $_SERVER['DOCUMENT_ROOT'] = '/home/username/webapps/example_application';
  $_ENV['DOCUMENT_ROOT'] = '/home/username/webapps/example_application';
?>

For completeness, if you're actually trying to change the document root where the application is served, then you might be better served using a Symbolic Link to Static/CGI/PHP application. This is described in this related community post.
