title: how to make a multi-lingual php site?
body: <p>I am developing a site using php and mysql. I want to know... what's a good way to deal with multi-lingual support? I want a user to be able to select from a drop down and select their language. Then everything (content, buttons, links) except the user-written content is in their language.</p>
  
  <p>What's a good way to approach this? Use a cookie? Session?</p>
