Examples
Example #1 MongoCursor::count() example
<?php
$collection->insert(array('x'=>1));
$collection->insert(array('x'=>2));
$collection->insert(array('x'=>3));
$cursor = $collection->find();
var_dump($cursor->count());
var_dump($cursor->count(true));
$cursor->limit(2);
var_dump($cursor->count());
var_dump($cursor->count(true));
?>
