MongoDB查询转换为PHP

Hey everyone I am trying to replicate this query in PHP using MongoClient.

db.rss.find({'channel__list.items.item.sd:ids.sd:id.sd:id': 
                       '6a81cc65- fc97-40d2-9c95-74cbfd25626e'})

Can someone help me out with this issue? I am not exactly sure how to access elements inside of elements using the find command on MongoClient, thank you!

    You might find this helps http://php.net/manual/en/mongo.queries.php

    $collection->find(array('channel__list.items.item.sd:ids.sd:id.sd:id' => '6a81cc65- fc97-40d2-9c95-74cbfd25626e'));
    

    Is the literal interpretation, although you will need to define $collection

    $m = new MongoClient("mongodb:///tmp/mongodb-20000.sock"); // file socket, but can use URL socket
    $collection = $m->selectCollection("foo", "bar.baz"); // choses DB & collection
    

    You can also define $collection separately to the DB Using

    $collection = $m->selectDB("foo")->selectCollection("bar.baz"); // chained
    // or
    $m->selectDB("foo"); // select DB (maybe in separate method)
    $collection = $m->selectCollection("bar.baz"); // (then set collection)
    

    Hope this Helps
