Answer 1

You can get the count of any array by using the count function.

You can access any sub-array by using it's array keys.

$records = $array['http://apps.facebook.com/moviecornpopcorn/index.php/ratemovie/comments?movieid=513']['data'];
$count = count($records);

See as well: Count elements in adjacent array

Answer 2

pretty nasty array key you have there :) so get the current element (with url as array key) values and count the values of it

<?php $data = current($yourarray); $dataCount = count($data); ?>
