PHP和MongoDB - 查询数组

Question

I can do a bounding box location query fine, like this:

$cursor = $coll->find(array('loc' => array('$within' => array('$box' => $box))));

And another basic query works:

$cursor = $coll->find(array('type' => $filter));

But when I try to combine both into a new query, it's not working:

$cursor = $coll->find(array(

    array('loc' => array('$within' => array('$box' => $box))), 

    array('type' => $filter)

)); 

Am I handling the query string incorrectly?

Answer 1

Your syntax is not correct, you should simply do:

$cursor = $coll->find(array(
    'loc' => array('$within' => array('$box' => $box)),
    'type' => $filter,
)); 

Ie, have one array with all the query parts.
