Mongodb查询PHP -每行1个文档 - Mongodb Query in PHP - 1 document per line

Mongodb Query in PHP - 1 document per line

我需要在结果中看到每行1个文档

$cursor = $collection->aggregate(
    array('$group' => array('_id' => array('year' => array('$year' => '$dia')),'sesiones' => array('$sum' => '$sesiones'),'usuarios' => array('$sum' => '$usuarios')))
);

当我输入这段代码时:

var_dump($cursor);

结果如下

array(2) { ["result"]=> array(8) { [0]=> array(3) { ["_id"]=> array(1) { ["year"]=> int(2016) } ["sesiones"]=> int(12930172) ["usuarios"]=> int(9943884) } [1]=> array(3) { ["_id"]=> array(1) { ["year"]=> int(2015) } ["sesiones"]=> int(18486839) ["usuarios"]=> int(15773531) } [2]=> array(3)

和我希望看到每行1个文档

thanks a lot

你可以使用

var_dump(iterator_to_array($cursor));

或者

foreach ($cursor as $doc) {
display $doc
}
