Navigate to page w/out .php extension

Hello,

I am trying to figure out if there is any way to be able to navigate to a webpage without having to type the .php extension into the address bar.  Currenly, If i want to go to my support page, I have to go to www.hondovfd.org/support.php, but I'd like to be able to just go to www.hondovfd.org/support.  Does anyone know if this is possible, and if so, how to do it?  I'd much rather not create redirects for every single page because that would take forever.
