You've asked the same question again! But I noticed a big error this time:
Instead of 'appid'
it should be 'appId'
. (note the capital I).
But another thing: no event of ikeausa is public, so you'll get an empty array in result. Try following, it will give you an event that is public-
$fb = new Facebook(array(
'appId'=>'app-id',
'secret'=>'app-secret'
));
$page_events = $fb->api('/Shadowfax.sahil/events', 'GET');
print_r($page_events);
