Question

我有以下代码：

<?php

require __DIR__ . '/vendor/autoload.php';

$client = new MongoDB\Client("mongodb://localhost:27017");
$collection = $client->bbcData->programmeData;
$result = $collection->find( [ '_id' => 'b007jwd9'] );

foreach ($result as $entry) {
    echo $entry['_id'], ': ', $entry['complete_title'], "\n";
}

?>

JSON如下：

{"complete_title":{"name":"wimsey - murder must advertise","episode":"sudden decease of a man in dress clothes"},"media_type":"audio","_id":"b007jwd9","categories":{"category1":["drama", "crime"]}}

我想打印出complete_title的名称，但是文档没有显示这个的语法。目前，我收到一条错误消息，指出complete_title是一个BSONDocument，因此无法将其转换为String。
