Share a very useful php7+mongodb class!

Due to project needs, the project has been upgraded tophp7. But after upgrading, I found that themongoextension cannot be used.php7.0The above only supportsmongodbextensions. Themongodbextended driver is more complicated and verbose to use than themonmgoextension. I've been looking for it online for a long time. Finally found a relatively simplemongodbclass. The syntax is similar tomongo. Clear and natural.

Because the project was contributed by foreign friends. So there is no clear document that can be read. Here are some commonly used methods.

Get instance

$uri = "mongodb://username:password@host/database"; $client = new \MongoDB\Client($uri);

Get collection

$collection = $client->selectCollection('test','test');

Get a piece of data

$data = $collection->findOne(['id'=>1]);

Get multiple pieces of data

$where = ['type'=>1]; $options = array( 'projection' => array('id' => 1, 'age' => 1, 'name' => -1), // 指定返回哪些字段 1 表示返回 -1 表示不返回 'sort' => array('id' => -1), // 指定排序字段 'limit' => 10, // 指定返回的条数 'skip' => 0, // 指定起始位置 ); $data = $collection->find($where,$options)->toArray(); var_dump($data);

Remove duplicates

$fileName = 'name'; $where = ['id' => ['$lt' => 100]] $ret = $this->collection->distinct($fileName,$where);

Insert a piece of data

$data = array( 'id' => 2, 'age' => 20, 'name' => '张三' ); $ret = $collection->insertOne($data); $id=$ret->getInsertedId();

Batch insert

$data = array( ['id' => 1, 'age' => 21, 'name' => '1xiaoli'], ['id' => 2, 'age' => 22, 'name' => '2xiaoli'], ['id' => 3, 'age' => 23, 'name' => '3xiaoli'], ['id' => 4, 'age' => 26, 'name' => '4xiaoli'], ['id' => 5, 'age' => 24, 'name' => '5xiaoli'], ['id' => 6, 'age' => 25, 'name' => '6xiaoli'], ); $ret = $collection->insertMany($data); # 返回插入id var_dump($ret->getInsertedIds());

Update one item

$ret = $collection->updateOne(array('id' => 2), array('$set' => array('age' => 56)));

Update multiple items

$ret = $collection->updateMany(array('id' => ['$gt' => 1]), array('$set' => array('age' => 56, 'name' => 'x')));

Delete one item

$ret = $collection->deleteOne(array('id' => 2));

Delete multiple items

$collection->deleteMany(array('id' => array('$in' => array(1, 2))));

aggregation

$ops = [ [ '$match' =>['type'=>['$in'=>[2,4]]] ], [ '$sort' => ['list.create_time' => -1] //sort顺序不能变，否则会造成排序混乱，注意先排序再分页 ], [ '$skip' => 0 ], [ '$limit' => 20000 ], ]; $data = $collection->aggregate($ops); foreach ($data as $document) { var_dump($document); }
