Php MongoDB Connectivity

Php provides mongodb driver to connect with mongoDB database. After installing it, we can perform database operations by using the php. Here, we are using Ubuntu 16.04 to create an example. This example includes the following steps.

1) Installing Driver

$ pecl install mongodb

2) Edit php.ini File

It is store in the apache server directory /etc/php/7.0/apache2/php.ini

$ extension = mongodb.so

3) Install mongo-php library

Following is the preferred way of installing this library with Composer.

$ composer require mongodb/mongodb

4) Create Php Script

// connect.php

<?php
require 'vendor/autoload.php';
// Creating Connection
$con = new MongoDB\Client("mongodb://localhost:27017");
// Creating Database
$db = $con->TheDeveloperBlog;
// Creating Document
$collection = $db->employee;
// Insering Record
$collection->insertOne( [ 'name' =>'Peter', 'email' =>'peter@abc.com' ] );
// Fetching Record
$record = $collection->find( [ 'name' =>'Peter'] );
foreach ($record as $employe) {
echo $employe['name'], ': ', $employe['email']."<br>";
}
?>

5) Execute Php Script

Execute this script on the localhost server. It will create database and store data into the mongodb.

localhost/php/connect.php

6) Enter into Mongo Shell

After executing php script, we can see the created database in mongodb.

$ mongo
