Php7+mongodb class is what kind of, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain in detail for you, people with this need can come to learn, I hope you can gain something.

Recommend a php7+ mongodb trigonal class

Due to the needs of the project, the project was upgraded to php7. But after the upgrade, I found that the mongo extension was no longer available. Only mongodb extensions are supported above php7.0. The driver of the mongodb extension is more complex and verbose than the monmgo extension. I've been looking for it online for a long time. Finally found a relatively concise mongodb class. The grammar is similar to that of mongo. Clear, natural.

Project address https://github.com/mongodb/mongo-php-library

Because the project is contributed by foreign friends. So there is no clear document to read. Here are some common 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), / / specify which fields to return 1 means return-1 means that no 'sort' = > array (' id' = >-1) is returned, / / specify sorting field 'limit' = > 10, / / specify the number of returned entries' skip' = > 0, / / specify the starting position) $data = $collection- > find ($where,$options)-> toArray (); var_dump ($data); deweighting $fileName = 'name';$where = [' id' = > ['$lt' = > 100]] $ret = $this- > collection- > distinct ($fileName,$where); insert a piece of data $data = array ('id' = > 2,' age' = > 20, 'name' = >' Zhang San'); $ret = $collection- > insertOne ($data); $id=$ret- > getInsertedId () Bulk 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); # return insert idvar_dump ($ret- > getInsertedIds ()); update a $ret = $collection- > updateOne (array ('id' = > 2), array (' $set' = > array ('age' = > 56)); update multiple $ret = $collection- > updateMany (array (' id' = > ['$gt' = > 1]), array ('$set' = > array ('age' = > 56,' name' = > x') Delete one $ret = $collection- > deleteOne (array ('id' = > 2)); delete multiple $collection- > deleteMany (array (' id' = > array ('$in' = > array (1,2) Aggregate $ops = [['$match' = > ['type'= > [' $in'= > [2p4], ['$sort' = > ['list.create_time' = >-1] / / sort order cannot be changed, otherwise it will cause sorting confusion. Please note that sorting is followed by paging], [' $skip' = > 0], ['$limit' = > 20000],] $data = $collection- > aggregate ($ops); foreach ($data as $document) {var_dump ($document);} is it helpful for you to read the above?
