编写php文件以将文档添加到mongoDB集合

<?php
require 'vendor/autoload.php'; // 引入MongoDB扩展

$mongoClient = new MongoDB\Client("mongodb://localhost:27017"); // 连接MongoDB数据库
$database = $mongoClient->selectDatabase("your_database_name"); // 选择数据库
$collection = $database->selectCollection("your_collection_name"); // 选择集合

$document = [
    'title' => 'Sample Document',
    'content' => 'This is a sample document.',
    'author' => 'John Doe',
    'created_at' => new MongoDB\BSON\UTCDateTime()
];

$result = $collection->insertOne($document); // 插入文档到集合
echo "Inserted document with ID: " . $result->getInsertedId();
?>
