title: %2F in URL breaks and does not reference to the .php file required
body: <p>I need to pass / as a variable as part of a URL. </p>
  
  <p>My structure looks like this: 
  www.domain.com/listings/page-1/city-Burnaby+South/type-Townhome/bedroom-2/bathroom-2</p>
  
  <p>In this case, it ultimately boils down to listings.php and everything else beyond it becomes parameters taht my PHP script parses through using the $_SERVER['REQUEST_URI'] var. </p>
  
  <p>However when one of hte variables becomes "Apartment/Condo" and the / becomes %2F via urlencode() in PHP when the URL is generated, the whole thing chokes and I get a "Not Found" error. </p>
  
  <p>How do I pass the / without breaking the URL? What am I missing? I thought the whole point of these urlencode() characters (%2F, %20 etc.) were there to escape these issues. </p>
