Set up

HTTP Adapter

As an HTTP client is necessary to the the MusicBrainz API client, you have to provide it as constructor argument. You may use any HTTP client by using an adapter instantiating MusicBrainz\AbstractHttpAdapter. This projects delivers an adapter for Guzzle 6, but you may write your own adapter for your preferred HTTP client.

Usage with Guzzle:

<?php
use MusicBrainz\MusicBrainz;
use MusicBrainz\HttpAdapter\GuzzleHttpAdapter;
use GuzzleHttp\Client;

$guzzleHttpAdapter = new GuzzleHttpAdapter(new Client);
$musicBrainz       = new MusicBrainz($guzzleHttpAdapter);

Don't forget to add Guzzle to your composer project, if not yet required.

composer require guzzlehttp/guzzle

Logger

Optionally, you may set any PSR-3 logger implementing Psr\Log\LoggerInterface by injecting it as a second constructor argument.

Usage with Guzzle and Monolog:

<?php
use Monolog\Logger;
use MusicBrainz\MusicBrainz;
use MusicBrainz\HttpAdapter\GuzzleHttpAdapter;
use GuzzleHttp\Client;

$guzzleHttpAdapter = new GuzzleHttpAdapter(new Client);
$logger            = new Logger('MusicBrainz API Client Logger');
$musicBrainz       = new MusicBrainz($guzzleHttpAdapter, $logger);

Don't forget to add Monolog to your composer project, if not yet required.

composer require monolog/monolog

MusicBrainz Credentials

All requests for user-tags or user-ratings require authentication.

<?php
/** @var \MusicBrainz\MusicBrainz $musicBrainz*/
$musicBrainz->config()
    ->setUsername('myUsername')
    ->setPassword('myPassword');

Custom API Path

By default, all requests are executed against the MusicBrainz API at https://musicbrainz.org/ws/2. You can set another base path (e. g. for your own MusicBrainz installation) as follows:

<?php
/** @var \MusicBrainz\MusicBrainz $musicBrainz*/
$musicBrainz->config()
    ->setApiUrl('https://example.com/ws/2');

Usage

Search Requests

The search API provides methods to search for the MusicBrainz core entities. For each of these entities there is a search method taking a specific filter object and a page filter for pagination. The return value will be a specific list object containing basic information about the matching entities. For more information you have to perform a lookup request with the MusicBrainz Identifier (MBID) of the entity.

The following example search for the artist named "Tom Waits" and limits the result list to the top match.

<?php
use MusicBrainz\Filter\PageFilter;
use MusicBrainz\Filter\Search\ArtistFilter;
use MusicBrainz\Value\Name;

$artistFilter = new ArtistFilter;
$artistFilter->addArtistNameWithoutAccents(new Name('Tom Waits'));
$pageFilter = new PageFilter(0, 1);

$artistList = $this->musicBrainz->api()->search()->artist($artistFilter, $pageFilter);

Lookup Requests

If you have the MusicBrainz Identifier (MBID) of an entity (through a search request), you can get more information about it by performing a lookup request. For each of the core entities there is a specific lookup method. As first argument you have to pass the MBID. The second argument is a list of additional fields the response object should contain.

The followig example looks up for the artist with MBID c3aeb863-7b26-4388-94e8-5a240f2be21b (who is Tom Waits), and requests to append information about his his recordings and works to the response.

<?php
use MusicBrainz\Supplement\Lookup\ArtistFields;
use MusicBrainz\Value\MBID;

$fields = (new ArtistFields)
    ->includeRecordings()
    ->includeWorks();

self::$artist = $this->musicBrainz->api()->lookup()->artist(
    new MBID('c3aeb863-7b26-4388-94e8-5a240f2be21b'),
    $fields
);

Browse Requests

Browse requests are a direct lookup of all the entities directly linked to another entity with a given MusicBrainz Identifier (MBID).

The following example looks up for all events directly linked to the artist with the MBID c3aeb863-7b26-4388-94e8-5a240f2be21b (who is Tom Waits). In analogy to normal lookup requests additional fields may be specified for the response, and a page filter may be added for pagination.

<?php
use MusicBrainz\Filter\Browse\Relation\Entity\EventRelation;
use MusicBrainz\Supplement\Browse\EventFields;

$eventRelation = (new EventRelation)
    ->artist(new MBID('4aae17a7-9f0c-487b-b60e-f8eafb410b1d'));
$eventFields = (new EventFields)
    ->includeTags();
$pageFilter = new PageFilter(0, 5);

$eventList = $musicBrainz->api()->browse()->event($eventRelation, $eventFields, $pageFilter);
