Getting error while collection has no data using MongoDB and PHP

Question

I am getting an array length of 1 even if my MongoDB collection is blank. I am using PHP and MongoDB.

code :

$listdata=$db->kf_poll_master->find();

 echo (count($listdata));exit;

Here my collection: kf_poll_master has no data still the array length is showing 1 in echo where it should come as 0.

@RohanKumar : I did as per you but it gave me this object(MongoCursor)#7 (0) { } output. I also did like this print_r($listdata) and it gave me this MongoCursor Object ( ) as poupt. — satya

MongoCollection::find() does not return a PHP array, but an object of class MongoCursor. You cannot use the native PHP count().

You should rather do :

echo $listdata->count();

Alternatively, you can convert the MongoCursor, which is an Iterator, to an array using iterator_to_array.
