DreamHost are now offering customers a choice in their version of PHP. The default arrangement is for PHP 4 running as a CGI application. Customers have been able to switch to using PHP as an Apache module if they wish. Now, however, the option to run PHP 5 as a CGI application is also available.
In an attempt to encourage developers to adopt best practices, things like
magic_quotes_gpc have been disabled for PHP 5, although they remain enabled for PHP 4. Across all PHP installations, DreamHost have wisely disabled
allow_url_fopen to further improve security. Their new wiki has information about the implications of disabling URL file access, as well as how to get around the issue by using the cURL library.
