Non-PHP CGI toolkits that support PHP-like CGI syntax?

I have some websites that use extJS with a PHP backend, and we're trying to move away from PHP entirely after a few security incidents. Due to extJS's license, there are concerns if we'd have to release the server-side code if we modified the javascript, so I'm looking instead to replace the back-end instead.

The calling syntax I'm mostly looking at is how PHP handles arrays. You might see something like:

?array[]=item1;array[]=item2;array=item3[]

rather than say, with perl's CGI.pm:

?array=item1;array=item2;array=item3

Are there CGI libraries for other languages that support this array syntax natively, or should I just hack something together myself?

(it's开发者_如何学编程 actually older extJS ... back when they claimed it was released under LGPL, before they posted their take on what LGPL was, which sounded nothing like what I was aware of, but we're not willing to go the legal route, I just haven't had the time to switch to some other JS library)
