如何使用“ New MongoDB \ Driver \ Manager”驱动程序获取PHP中的集合{Mongodb}列表

Question

我想使用php获取monogoDB的所有集合。

使用波纹管代码我只能得到一个收藏集。

<?php
$manager = new MongoDB\Driver\Manager('mongodb://localhost:27017');
$listdatabases = new MongoDB\Driver\Command(["listCollections" => 1]);
$res = $manager->executeCommand("mydatabasename", $listdatabases);
$collections = current($res->toArray());
print_r($collections);

stdClass Object
(
    [name] => collectionname
    [type] => collection
    [options] => stdClass Object
        (
        )

    [info] => stdClass Object
        (
            [readOnly] => 
            [uuid] => MongoDB\BSON\Binary Object
                (
                    [data] => �����B���tqIB
                    [type] => 4
                )

        )

    [idIndex] => stdClass Object
        (
            [v] => 2
            [key] => stdClass Object
                (
                    [_id] => 1
                )

            [name] => _id_
            [ns] => collectionname
        )

)

但是我想要所有收藏夹列表。

MongoDB版本：3.4.16

Php版本：7.1

Answer 1

您只需要从

中删除电流

$collections = current($res->toArray());

您将获得所有收藏。应该是

$collections = $res->toArray();
