As this question is quite old and for PHP  here is a way to do it in the  currently  very popular PHP framework Laravel   To encode the query string for a path in your application  give your routes names and then use the route   helper function like so   route  documents list      foo    gt   bar       The result will look something like   http   localhost documents list foo bar   Also be aware that if your route has any path segment parameters e g   documents  id   then make sure you pass an id argument to the route   parameters too  otherwise it will default to using the value of the first parameter
