    \'/(\\/|\\.|-|_|=|\\?|\\&|html|shtml|www|php|cgi|htm|aspx|asp|index|com|net|o         


        

Answer 1

I'm guessing you're building a URL router of some kind.

Detecting which parameters are useful and which are not should not be part of this code. It may vary per page whether a short parameter is relevant.

In this case, couldn't you just ignore the 1'th element? Your page should (or 'handler') should have knowledge over which parameters it wants to be called with, it should do the triage.
