MongoCursor::fields — Sets the fields for a query

설명

public MongoCursor MongoCursor::fields ( array $f )

Fields are specified by "fieldname" : bool. TRUE indicates that a field should be returned, FALSE indicates that it should not be returned. You can also use 1 and 0 instead of TRUE and FALSE.

Thus, to return only the "summary" field, one could say:


<?php

$cursor->fields(array("summary" => true));

?>

To return all fields except the "hidden" field:


<?php

$cursor->fields(array("hidden" => false));

?>

인수

f: Fields to return (or not return).
