The MongoCursor class

Wstęp

Result object for database query.

The database is not actually queried until next() or hasNext() is called. Before the database is queried, commands can be strung together, as in:

<?php
$cursor = $collection->find()->limit(10);

// database has not yet been queried, so more search options can be added
$cursor = $cursor->sort(array("a" => 1));

var_dump($cursor->getNext());
// now database has been queried and more options cannot be added

// so this will throw an exception:
$cursor->skip(4);
?>
