title: Any benefit in using a form vs a link for logout functionality?
body: <p>I'm building a web app and just working on the logout functionality (simple session unset / meta refresh/redirect code on logout.php)</p>
  
  <p>Possible a simple question (though I've hunted around on Google to no avail), but for the logout button on the site, is there any benefit in using a form that submits to logout.php vs a button graphic with an a href that links to the same page? </p>
  
  <p>Functionally, they both seem to work the same, but is there any potential security issue etc?</p>
  
  <p>Thanks heaps!</p>
