如何使用PHP限制/分页我的MongoDB搜索结果？

<?php
// 连接到MongoDB
$mongoClient = new MongoDB\Client("mongodb://localhost:27017");

// 选择数据库和集合
$database = $mongoClient->selectDatabase("mydb");
$collection = $database->selectCollection("mycollection");

// 定义每页显示的文档数量和当前页码
$perPage = 10;
$page = isset($_GET['page']) ? (int)$_GET['page'] : 1;

// 计算要跳过的文档数量
$skip = ($page - 1) * $perPage;

// 执行搜索查询并限制/分页结果
$query = []; // 定义查询条件
$options = [
    'skip' => $skip,
    'limit' => $perPage
];
$result = $collection->find($query, $options);

// 输出搜索结果
foreach ($result as $document) {
    echo $document['field1'] . "<br>";
    echo $document['field2'] . "<br>";
    // ...
}

// 输出分页链接
$totalDocuments = $collection->count($query);
$totalPages = ceil($totalDocuments / $perPage);

for ($i = 1; $i <= $totalPages; $i++) {
    echo "<a href='?page=$i'>$i</a> ";
}
?>
