mongodb学习（三）

<?php

$manager = new MongoDB\Driver\Manager("mongodb://127.0.0.1:27017");
$bulk = new MongoDB\Driver\BulkWrite;
$bulk->insert(['x' => 1, 'class' => 'toefl', 'num' => '18']);
$bulk->insert(['x' => 2, 'class' => 'ielts', 'num' => '26']);
$bulk->insert(['x' => 3, 'class' => 'sat', 'num' => '35']);
$manager->executeBulkWrite('test.log', $bulk);
//

$filter = ['x' => ['$gt' => 1]];
$options = [
    'projection' => ['_id' => 0],
    'sort' => ['x' => -1],
];
$query = new MongoDB\Driver\Query($filter, $options);
$cursor = $manager->executeQuery('test.log', $query);
foreach ($cursor as $document) {
    print_r(json_decode(json_encode($document),JSON_UNESCAPED_UNICODE));  //stdClass格式转换成普通的数组格式
}

php7对于mongodb的基本操作

其他参数和操作可以参考手册：http://php.net/manual/zh/book.mongodb.php

还是推荐使用封装的类库来操作，省得麻烦
