由於專案需要，把專案升級到了php7。但是升級了之後發現mongo擴充功能不能用了。 php7.0以上只支援mongodb擴充了。而mongodb擴展的驅動使用起來比monmgo擴展顯得很複雜，囉嗦。在網路上找了很久。終於找到了一個比較簡潔的mongodb類別。文法跟mongo的差不多。清晰，自然。

因為專案是國外友人貢獻的。所以沒有可以看的很明白的文檔。這裡整理了一些常用的方法。
取得實例
$uri = "mongodb://username:password@host/database"; $client = new \MongoDB\Client($uri);
取得集合
$collection = $client->selectCollection('test','test');
取得一個資料
$data = $collection->findOne(['id'=>1]);
取得多個資料
$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);
去重#
$fileName = 'name'; $where = ['id' => ['$lt' => 100]] $ret = $this->collection->distinct($fileName,$where);
插入一條資料
$data = array( 'id' => 2, 'age' => 20, 'name' => '张三' ); $ret = $collection->insertOne($data); $id=$ret->getInsertedId();
批次插入
$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);
}
