MongoDB Golang driver installation + First call to MONGO Command.

This is a creation in Article, where the information may have evolved or changed.

Under the latest version of the Mongodb3.2, under the MongoDB PHP driver.

PHP version is php7,php operation MongoDB class file, the results of the MONGO class does not exist, do not know whether the driver download is not the latest version of the matter.

In the table below, MongoDB and MONGO refer to the new and legacy MongoDB PHP driver, respectively. Phplib refers to the Userland library.

The driver does not a support older versions of MongoDB.

There seems to be a temporary driver for PHP7 's MongoDB ...

Since PHP does not, then use Golang, with Golang to do a Web API bar, anyway recently golang hot.

Search under MongoDB Golang driver, many people recommend MgO, then with the public bar, to GitHub on the search of MgO, installation download.

Dial ("server1.example.com,server2.example.com")        if err! = Nil {                panic (err)        }        defer session. Close ()        //Optional. Switch the session to a monotonic behavior.        Session. SetMode (MgO. Monotonic, True)        C: = Session. DB ("Test"). C ("People")        err = C.insert (&person{"Ale", "+55 8116 9639"},               &person{"Cla", "+55" 8402 8510 "}) 
  if Err! = Nil {                log. Fatal (Err)        }        Result: = person{}        err = C.find (Bson. m{"name": "Ale"}). One (&result)        if err! = Nil {                log. Fatal (Err)        }        fmt. Println ("Phone:", result.) Phone)}

Simple plus easy, install run demo, finished.

The document address of the MongoDB command:

The function to be implemented is to insert a certain number of latitude and longitude coordinate points and then query the coordinate points within a certain distance according to the specified latitude and longitude.
