    Here is an example of Query to retrieve the records from MangoDB collection using a filter. It will return in this case just one record that satisfy the filter id = 2.

    Considering the following MangoDB collection:

    <?php
    /* my_collection */

    /* 1 */
    {
            "_id" : ObjectId("5707f007639a94cbc600f282"),
            "id" : 1,
            "name" : "Name 1"
    }

    /* 2 */
    {
            "_id" : ObjectId("5707f0a8639a94f4cd2c84b1"),
            "id" : 2,
            "name" : "Name 2"
    }
    ?>

    I'm using the following code:
    <?php
    $filter     = ['id' => 2];
    $options = [
           'projection' => ['_id' => 0],
    ];
    $query = new MongoDB\Driver\Query($filter, $options);
    $rows = $mongo->executeQuery('db_name.my_collection', $query); // $mongo contains the connection object to MongoDB
    foreach($rows as $r){
           print_($r);
    }
    ?>

    Careful with your filter here - integers and strings are different.

    With a string ID '1000', this query will mysteriously return 0 results; wasted time figuring out what was going on:

    $query = new MongoDB\Driver\Query(['_id' => 1000]);

    This will work:

    $query = new MongoDB\Driver\Query(['_id' => '1000']);

    Would be nice if the library could handle this.
