一：插入数据

例：向默认的test数据库的wj表中插入数据$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");

// 插入数据

$bulk = new MongoDB\Driver\BulkWrite;

$bulk->insert(['id' => 1, 'name'=>'测试', 'url' => 'http://www.百度.com']);

$manager->executeBulkWrite('test.wj', $bulk);

2：查询数据

查询test数据库的wj表中name值不为测试的数据$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");

$filter = ['name' => '测试'];

$options = [

'projection' => ['_id' => 0],

'sort' => ['name' => -1],

];

$query = new MongoDB\Driver\Query($filter, $options);

$cursor = $manager->executeQuery('test.wj', $query);

foreach ($cursor as $document) {

print_r($document);

}

3:更新数据

将test数据库中的wj表中id为1的数据中name字段变为测试1234，$bulk = new MongoDB\Driver\BulkWrite;

$bulk->update(

['id' => 1],

['$set' => ['name' => '测试1234']],

['multi' => false, 'upsert' => false]  #multi表示只更新一条数据，upsert表示如果不存在update的记录，不进行插入操作

);

$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");

$writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY, 1000);

$result = $manager->executeBulkWrite('test.wj', $bulk, $writeConcern);

4：删除数据$bulk = new MongoDB\Driver\BulkWrite;

$bulk->delete(['id' => 1], ['limit' => 1]);   // limit 为 1 时，删除第一条匹配数据

$bulk->delete(['id' => 2], ['limit' => 0]);   // limit 为 0 时，删除所有匹配数据

$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");

$writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY, 1000);

$result = $manager->executeBulkWrite('test.wj', $bulk, $writeConcern);
