4. Collection $ = $ DB -> Mongo ; // set selection
5. $document = array(
6. "title" => "MongoDB",
7. "description" => "database",
8. "likes" => 100,

11. );
12. $collection->insert($document);
13. echo "data insertion success" ;
14. ?>

Performing the above procedure, the output results are as follows:

1. Data inserted successfully

Export

1. {
2. "_id": ObjectId("57512b3a57c9150f178b4567"),
3. "title" : "MongoDB",
4. "description" : "database",
