<? PHP  //  The default port 27017 is used to connect to the local machine. Of course, you can also connect to the remote host such as 192.168.0.4: 27017. If the port is 27017, the port can be omitted.  $ M = New  Mongo ();  //  Select the comedy database. If the database is not created before, you can also use $ M-> selectdb ("Comedy ");  $ DB = $ M -> Comedy;  // Select the collection set in comedy, which is equivalent to the table in RDBMS. You can also use  $ Collection = $ DB -> Collection;  $ DB -> Selectcollection ("Collection" );  //  Add an element  $ OBJ = Array ("Title" => "Calvin and Hobbes -". Date ('I: s'), "author" => "Bill Watterson" );  // Add $ OBJ to $ collection  $ Collection -> Insert ( $ OBJ  );  //  Add another element  $ OBJ = Array ("Title" => "XKCD -". Date ('I: s'), "online" => True  );  $ Collection -> Insert ( $ OBJ  ); //  Query all records  $ Cursor = $ Collection -> Find ();  //  Traverse all documents in the Set  Foreach ( $ Cursor   As   $ OBJ  ){  Echo   $ OBJ ["Title"]. "\ n" ;}  // Delete all data  $ Collection -> Remove ();  //  Delete HM as name  $ Collection -> Remove ( Array ('Name' => 'hm' ));  //  Disconnect MongoDB  $ M -> Close (); ?>
