PHP＆MongoDB-查询数组

Question

I can do a bounding box location query fine, like this: 我可以很好地进行边界框位置查询，如下所示：

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

And another basic query works: 另一个基本查询有效：

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

But when I try to combine both into a new query, it's not working: 但是，当我尝试将两者合并为一个新查询时，它不起作用：

$cursor = $coll->find(array(

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

    array('type' => $filter)

));

Am I handling the query string incorrectly? 我对查询字符串的处理不正确吗？

Answer 1

Your syntax is not correct, you should simply do: 您的语法不正确，只需执行以下操作：

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

Ie, have one array with all the query parts. 即，具有一个包含所有查询部分的数组。
