I was browsing Symfony's website. I didn't really feel like I need all the functionality the framework offers, but I did like the routing part. It allows you to specify URL pattern like this
/some/path/{info}
Now for URL like www.somewebsite.com/app.php/some/path/ANYTHING it would allow you to send client a response specific for this URL. You could also use string ANYTHING and use it similar as GET parameter.
There is also option to hide app.php part of the URL which leaves us URL like www.somewebsite.com/some/path/ANYTHING.
My question is what's best approach to do this without a complex framework?
