.htaccess to run PHP5 on a server that defaults .php to PHP4, when your ultimate target is a PHP5 server.
The advantage of this architecture is that since all the pages are delivered through index.php5, they are processed as PHP5, although they are named as .php.
Also - if you have a PHP5 application, you MAY be able to use the same approach, if you put PHP5 and PHP4 on the same server.
This is a dojo validation loop. Send it an array of input ids (with dojoTypes), and it will ensure they’re valid.
