get a # from a url in php

问题:

I'm trying to code with the facebook API

here it says : http://developers.facebook.com/docs/authentication/javascript to get the access_token thing, but it's after a # and not a ?

so how can I get it ?

http://www.example.com/callback#access_token=...&expires_in=...

回答1:

You won't be able to do it in PHP - you can only access it in javascript - the fragment/hash never reaches the server, it is processed by the browser

in Javascript, you can access the fragment using

window.location.hash

回答2:

The fragment identifier is only used client side. The browser doesn't send it to the server, so you can't access it with PHP.

To quote the page you link to:

Your JavaScript library can read the token from the URL and store it in a cookie for future use.

You have to use JS to read it before it can be sent to the server.
