mongodb是一个介于关系型数据库和非关系型数据库间的数据库，而且能够实现排序等相关的操作，是对redis的一个升级，同时mongodb中的数据库和mysql的类似，数据库的集合和redis相似，开启我们对mongodb的认识吧。

1.插入数据

$manager = new MongoDB\Driver\Manager('mongodb://localhost:27017');
$bulk = new MongoDB\Driver\BulkWrite;
$bulk->insert(['name' => 'phptest', 'age' => 27]);
$bulk->insert(['name' => 'phptest1', 'age' => 28]);
//
$writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY, 1000);//可选，修改确认
$res = $manager->executeBulkWrite('flstest.mongo', $bulk, $writeConcern)->getInsertedCount(); //获取插入成功返回的条数
echo '<pre>';
var_dump($res);

2.删除数据

$manager = new MongoDB\Driver\Manager('mongodb://localhost:27017');
$bulk = new MongoDB\Driver\BulkWrite;
$bulk->delete(['name' => 'phptest']);
$writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY, 1000);//可选，修改确认
$res = $manager->executeBulkWrite('flstest.mongo', $bulk, $writeConcern)->getDeletedCount(); //获取成功删除的条数
echo '<pre>';
var_dump($res);

3.修改数据

$manager = new MongoDB\Driver\Manager('mongodb://localhost:27017');
$bulk = new MongoDB\Driver\BulkWrite;
$bulk->update(
    ['name' => 'phptest'],
    ['$set' => ['age' => 34, 'promise' => '2222']]
);
$writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY, 1000);//可选，修改确认
$res = $manager->executeBulkWrite('flstest.mongo, $bulk, $writeConcern)->getModifiedCount(); //获取更新的条数
echo '<pre>';
print_r($res);

4.查询数据

//数据查询操作
$manager = new MongoDB\Driver\Manager('mongodb://localhost:27017');
$query = new MongoDB\Driver\Query(['age' => 26], ['sort' => ['age' => 1]]);
$cursor = $manager->executeQuery('fls_db.test', $query)->toArray();

foreach($cursor as $doc) {
    echo '<pre>';
    var_dump($doc->name,$doc->age);
}
//这里还不知道怎样获取id，下次找到回头添加进去
