分享一個很有用的php7+mongodb類！

由于項目需要，把項目升級到了php7。但是升級了之后發(fā)現(xiàn)mongo擴展不能用了。php7.0以上只支持mongodb擴展了。而mongodb擴展的驅動使用起來比monmgo擴展顯得很復雜，啰嗦。在網(wǎng)上找了很久。終于找到了一個比較簡潔的mongodb類。語法跟mongo的差不多。清晰，自然。

項目地址https://github.com/mongodb/mongo-php-library

因為項目是國外友人貢獻的。所以沒有可以看的很明白的文檔。這里整理了一些常用的方法。

獲取實例

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

獲取集合

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

獲取一條數(shù)據(jù)

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

獲取多條數(shù)據(jù)

$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, // 指定返回的條數(shù)     'skip' => 0, // 指定起始位置 ); $data = $collection->find($where,$options)->toArray(); var_dump($data);

去重

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

插入一條數(shù)據(jù)

$data = array(     'id' => 2,     'age' => 20,     'name' => '張三' ); $ret = $collection->insertOne($data); $id=$ret->getInsertedId();

批量插入

$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());

更新一條

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

更新多條

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

刪除一條

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

刪除多條

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

聚合

$ops = [     [         '$match' =>['type'=>['$in'=>[2,4]]]     ],     [         '$sort' => ['list.create_time' => -1]  //sort順序不能變，否則會造成排序混亂，注意先排序再分頁     ],     [         '$skip' => 0     ],     [         '$limit' => 20000     ], ]; $data = $collection->aggregate($ops); foreach ($data as $document) {     var_dump($document); }
