You can even use PHP PEAR php_beautifier without Apache !
# aptitude install php-pear
# pear install php_beautifier
# pear install channel://pear.php.net/php_beautifier-0.1.13
$ php_beautifier myfile.php
Now you don't need coding standards to create beautiful PHP since PHP PEAR even has a http://pear.php.net/package/PHP_Beautifier !
Who said open source projects didn't have documentation
