resource mongo_query ( resource $connection , string $ns , array $query , int $skip , int $limit , array $sort , array $fields , array $hint )

$searchterm = "pandas";

$pagenum = 2;
$resultsPerPage = 10;

$conn = mongo_connect("localhost", true);
if (!$conn) {
   die("Could not connect.");
}
$cursor = mongo_query($conn, "zoo.animals", array("name" => $searchterm), ($pagenum-1)*$resultsPerPage, $resultsPerPage, null, null, null);
