.htaccess security by loading files through the PHP parser. A good way around\n\
this is to define doc_root in your php3.ini file to something other than your\n\
top-level DOCUMENT_ROOT. This way you can separate the part of your web space\n\n\
which uses PHP from the normal part using .htaccess security. If you do not have\n\
any .htaccess restrictions anywhere on your site you can leave doc_root undefined.\n\
