With the advent of PHP7 the old mongodb driver is no more supported.

The new driver available is a little bit low-level compared to the previous one so it can be a bit complicated to work with.

This is what this library was conceived for.

Installation

Using composer is quite simple, just run the following command:

$ composer require alex-qiu/php7-mongo-adapter

Prerequisites

Before using this library you should make sure to have installed PHP7.0 or major and MongoDb driver from pecl.

For those using a Linux distribution (make sure to have pecl installed) just run:

$ sudo pecl install mongodb

After that you should put the following string

extension=mongodb.so

Inside your php.ini

Usage

At first you need to define a connection string.

The format for connection strings is:

mongodb://[username:password@]host1[:port1][,host2[:port2],...[,hostN[:portN]]][/[database][?options]]

For more information see the link: https://docs.mongodb.com/manual/reference/connection-string/

Once defined you need to instantiate a new Adapter:

use MongoDriver\Adapter;

// Enstablish a connection.
$adapter = new Adapter();
$adapter->connect(CONNECTION_STRING);

At this point you want to select a Database where do your query:

$adapter->selectDB('myDatabase');

NOTE: you could select a database directly on the constructor passing the database name as the 2nd parameter.

Find

Once selected the database we can simply query for the collection we want:

$items = $adapter->find('myCollection');

You can also filter your query:

use MongDriver\Filter;

$filters =
[
    new Filter('myField1', 'myValue1', Filter::IS_EQUALS),
    new Filter('myField2', ['myValue2', 'myValue3'], Filters::IS_IN_ARRAY)
];

$items = $adapter->find('myCollection', $filters);

Insert

If you want to insert an item you have simply to pass an array or an object to the insert function specifying the collection:

$item = new Person();
$item->name = 'Thomas';
$item->surname = 'Cocchiara');

// or: $item = ['name' => 'Thomas', 'surname' => 'Cocchiara'];

$adapter->insert('people', $item);

Hope you guys find this library useful.

Please share it and give me a feedback :)
