title: What to use for Web backend development? Perl? PHP?
body: <p>I'm looking to setup a pretty advanced web-based interface for a B2B application. I'm looking for a backend language to generate templates for the front end, pass the JSON data back and forth, etc.</p>
  
  <p>I used to use Perl for that back in the day. However, it seems it's not as common anymore. Why is that? </p>
  
  <p>If not Perl - what to use and why?</p>
