Dear all,

I have written up my first php script to learn facebook API stuff.It goes like this:

require_once('facebook/client/facebook.php');

$facebook = new Facebook('0fff13540b7ff2ae94be38463cb4fa67','8a029798dd463be6c94cb8d9ca851696'); http://stackoverflow.com/questions/ask

$fb_user = $facebook->require_login();

?>

Hello ' useyou='false' possessive='true' />! Welcome to my first application!

I put "facebook.php" in the same directory as my php script.

However,after I deploy the php on a web server and link it with facebook and run it,I got error saying:

"Fatal error: Call to undefined method Facebook::require_login() in /home/a2660104/public_html/facebook-php-sdk-94fcb13/src/default.php on line 16"

Could anyone help me a bit on this?I am a beginner to the facebook app programming.Thanks a lot!
