I’m new to Facebook API and I already search a LOT to solved this problem but I’m not successful in finding one.
The browser is still getting the cookies of the last session even after the user have logged out of facebook.
Here’s how it is done:
1. User logged in to facebook.
2. Open application.
3. Logged out of facebook.
3. Open application (not logged in) and the application will load with an error
Message: file_get_contents(https://graph.facebook.com/me/friends?access_token=157847364248123|2.pqWqIaCD8BKobvG_kJy9sA__.3600.1295859600-100001714363073|QfoJpTH-slOry2K1FepeyW8z5f8) [function.file-get-contents]: failed to open stream: HTTP request failed! HTTP/1.0 400 Bad Request
I think I need to clear cookies when the user ticked logout in facebook but I don’t know how to do it in PHP SDK. Please help. Thanks!
