title: php how to add php code in the twitter callback url?
body: <p>I am trying to start a new app on dev.twitter.com, and in the callback URL I want to pass a link like: <code>www.text.com?number=&lt;?= $var?&gt;</code> but it won't let me.</p>
  
  <p>Any ideas? Thanks.</p>
  
  <p>Edit: my link will eventually look like this: <code>www.text.com?number=123456</code></p>
  
  <p>But it will depend on who is logged in, so the number could be any 6 numbers, so I'm thinking the callback URL has to have that var inside it.</p>
