OneDrive SDK for PHP

The OneDrive SDK for PHP is an open source library that allows PHP applications to interact programmatically with the OneDrive REST API.

It supports operations such as creating, reading, updating, deleting (CRUD) files and folders, as well as moving or copying them to other folders.

Requirements

Using the OneDrive SDK for PHP requires the following:

• PHP 7.3 or newer ;
• Composer or a manual install of the dependencies mentioned in composer.json.

Testing

Running its functional tests also require:

• A OneDrive web application configured with http://localhost:7777/ as its redirect URI ;
• A WebDriver server, for example the Selenium's Java standalone server ;
• A Chrome browser & ChromeDriver, and they must be usable by the WebDriver server.

Installation

The recommended way to install OneDrive SDK for PHP is to install it using Composer:

composer require krizalys/onedrive-php-sdk

If you are not already using Composer in your PHP project, refer to the Composer documentation to learn how to set it up.

Quick start

To use the OneDrive SDK for PHP, you require a web application exposing a URL initiating the authorization flow. Typically, this URL, referred to as your web application's Redirect URI, is a PHP script requesting an authorization token. This token is required whenever your web application interacts with your users' OneDrive contents and may be reused across multiple calls. An example of such a web application is our functional test suite.

You also require a OneDrive application. To register such an application, first sign in to Microsoft Azure, then visit App registrations and add a registration for your application. While registering your application, you need to set its Redirect URI, explained above. We currently only support Web redirect URIs.

Once created, your application is assigned an Application (client) ID, referred to as its Client ID. In Certificate & secrets, you also need to add at least one Client secret. Warning: Client Secrets are similar to passwords or private keys by allowing an application to identify as yours: therefore, Client Secrets should be kept private.

Once you have a Redirect URI, a Client ID, and a Client Secret, your web application can start using the OneDrive SDK for PHP in three steps.

Step 1: create your configuration

As you may need them from several scripts, we recommend saving your Client ID, Client secret and Redirect URI in a configuration file, for example:

config.php

<?php

return [
    /**
     * Your OneDrive client ID.
     */
    'ONEDRIVE_CLIENT_ID' => '<YOUR_CLIENT_ID>',

    /**
     * Your OneDrive client secret.
     */
    'ONEDRIVE_CLIENT_SECRET' => '<YOUR_CLIENT_SECRET>',

    /**
     * Your OneDrive redirect URI.
     */
    'ONEDRIVE_REDIRECT_URI' => 'http://your.domain.com/redirect.php',
];

Step 2: direct your users to the sign in page

This script is responsible for, given a set of privileges, fetching a log in URL from the OneDrive API. It needs to direct users to this URL to initiate their log in and privilege granting process. The script should look like this:

index.php

<?php

($config = include __DIR__ . '/config.php') or die('Configuration file not found');
require_once __DIR__ . '/vendor/autoload.php';

use Krizalys\Onedrive\Onedrive;

// Instantiates a OneDrive client bound to your OneDrive application.
$client = Onedrive::client($config['ONEDRIVE_CLIENT_ID']);

// Gets a log in URL with sufficient privileges from the OneDrive API.
$url = $client->getLogInUrl([
    'files.read',
    'files.read.all',
    'files.readwrite',
    'files.readwrite.all',
    'offline_access',
], $config['ONEDRIVE_REDIRECT_URI']);

session_start();

// Persist the OneDrive client' state for next API requests.
$_SESSION['onedrive.client.state'] = $client->getState();

// Redirect the user to the log in URL.
header('HTTP/1.1 302 Found', true, 302);
header("Location: $url");

Step 3: get an OAuth access token

After the users follow this URL, they are required to sign into their Microsoft account, and they are asked whether they agree to allow your web application to access their OneDrive account.

If they do, they are redirected to your Redirect URI and a code is passed in the query string of this URL. The script at this URL essentially:

1. Instantiates a Client from your configuration and the state from previous instantiations ;
2. Obtains an OAuth access token using Client::obtainAccessToken(), passing it the code received ;
3. Starts interacting with the files and folders stored in their OneDrive account, or delegates this responsibility to other scripts which in turn may spawn other Client instances from the same state.

It typically looks like this (replace /path/to by the appropriate values):

redirect.php

<?php

($config = include __DIR__ . '/config.php') or die('Configuration file not found');
require_once __DIR__ . '/vendor/autoload.php';

use Krizalys\Onedrive\Onedrive;

// If we don't have a code in the query string (meaning that the user did not
// log in successfully or did not grant privileges requested), we cannot proceed
// in obtaining an access token.
if (!array_key_exists('code', $_GET)) {
    throw new \Exception('code undefined in $_GET');
}

session_start();

// Attempt to load the OneDrive client' state persisted from the previous
// request.
if (!array_key_exists('onedrive.client.state', $_SESSION)) {
    throw new \Exception('onedrive.client.state undefined in $_SESSION');
}

$client = Onedrive::client(
    $config['ONEDRIVE_CLIENT_ID'],
    [
        // Restore the previous state while instantiating this client to proceed
        // in obtaining an access token.
        'state' => $_SESSION['onedrive.client.state'],
    ]
);

// Obtain the token using the code received by the OneDrive API.
$client->obtainAccessToken($config['ONEDRIVE_CLIENT_SECRET'], $_GET['code']);

// Persist the OneDrive client' state for next API requests.
$_SESSION['onedrive.client.state'] = $client->getState();

// Past this point, you can start using file/folder functions from the SDK, eg:
$file = $client->getRoot()->upload('hello.txt', 'Hello World!');
echo $file->download();
// => Hello World!

$file->delete();

Versioning

OneDrive SDK for PHP adheres to Semantic Versioning: we are committed not to introduce breaking changes to the public API without incrementing the major version number. We also try to document such changes in the changelog.

However, we only consider symbols marked with the @api annotation to be part of the public API and subject to Semantic Versioning requirements. Other symbols are considered internal and may change or get removed without a major version increment. To avoid breaking changes, use only symbols from the public API in your code.

Testing

To run the functional test suite:

1. Set your application configuration at test/functional/config.php ;

2. Run your WebDriver server, for example:

   java -jar selenium-server-standalone-3.141.59.jar
   

3. Run the functional test suite (it assumes that WebDriver listening on port 4444):

   vendor/bin/paratest --functional --configuration test --testsuite 'Functional tests' --bootstrap test/functional/bootstrap.php
   

4. Repeat step 3 as needed.
