Requirements

• MongoDB server running on port usually 27017. (type mongod on command prompt to run mongodb server)
• Php installed as either cgi or fpm with MongoDB extension installed(MongoDB extension is not bundled with default php)
• Composer library(mongodb/mongodb).(In the project root run php composer.phar require "mongodb/mongodb=^1.0.0" to install the MongoDB library)

If everything is ok you are ready to move on.

Check For Php installation

if not sure check Php installation by running php -v on command prompt will return something like this

PHP 7.0.6 (cli) (built: Apr 28 2016 14:12:14) ( ZTS ) Copyright (c) 1997-2016 The PHP Group Zend Engine v3.0.0, Copyright (c) 1998-2016 Zend Technologies

Check For MongoDB installation

Check MongoDB installation by running mongo --version will return MongoDB shell version: 3.2.6

Check For Composer installation

Check for Composer installation by running php composer.phar --version will return Composer version 1.2-dev (3d09c17b489cd29a0c0b3b11e731987e7097797d) 2016-08-30 16:12:39 `

Connecting to MongoDB from php

<?php

  //This path should point to Composer's autoloader from where your MongoDB library will be loaded
  require 'vendor/autoload.php';

// when using custom username password
 try {
       $mongo = new MongoDB\\Client('mongodb://username:password@localhost:27017');
       print_r($mongo->listDatabases());
 } catch (Exception $e) {
       echo $e->getMessage();
 }

// when using default settings
 try {
       $mongo = new MongoDB\\Client('mongodb://localhost:27017');
       print_r($mongo->listDatabases());
 } catch (Exception $e) {
       echo $e->getMessage();
 }

The above code will connect using MongoDB composer library(mongodb/mongodb) included as vendor/autoload.php to connect to the MongoDB server running on port: 27017. If everything is ok it will connect and list an array, if exception occurs connecting to MongoDB server the message will be printed.
