Lite PHP SDK for the FamilySearch API.

Warning: this SDK requires hard-coding the API endpoint URLs. That is considered bad practice when using the API. In most cases, FamilySearch does not consider URL changes as breaking changes. Read more about dealing with change.

There is a sample app in the /examples directory that is deployed to http://fs-php-lite-sdk.herokuapp.com/examples/.

Usage

include_once('FamilySearch.php');

// Create the SDK instance
$fs = new FamilySearch([
  'environment' => 'production',
  'appKey' => 'ahfud9Adjfia',
  'redirectUri' => 'https://example.com/fs-redirect',
  
  // Tell it to automatically save and load the access token from $_SESSION. 
  'sessions' => true, // This defaults to true
  'sessionVariable' => 'FS_ACCESS_TOKEN',
  
  // Necessary for when the developer wants to store the accessToken somewhere
  // besides $_SESSION
  'accessToken' => '',
  
  // How many times should a throttled response be retried? Defaults to 5
  'maxThrottledRetries' => 5,
  
  // Activate pending modifications
  'pendingModifications' => ['consolidate-redundant-resources', 'current-person-401'],
  
  // Modify the default user agent by appending this value
  'userAgent' => 'myApp/1.2.3',
  
  // Enable optional serialization and deserialization with objects via gedcomx-php
  'objects' => true
]);

// OAuth step 1: Redirect
$fs->oauthRedirect();

// OAuth step 2: Exchange the code for an access token.
//
// This will automatically retrieve the code from $_GET and exchange it for
// an access token. The access token is contained in the response object if the
// request was successful. The token doesn't need to be saved to a variable if
// sessions are enabled because the SDK will automatically save it.
$response = $fs->oauthResponse();

// Get the current user
$response = $fs->get('/platform/users/current');

// All response objects have the following properties
$response->statusCode;     // Integer
$response->statusText;     // String
$response->headers;        // Array
$response->effectiveUrl;   // String
$response->body;           // String
$response->requestMethod;  // String
$response->requestHeaders; // Array
$response->requestBody;    // String
$response->redirected;     // Boolean; defaults to false
$response->throttled;      // Boolean; defaults to false
$response->curl;           // A reference to the curl resource for the request

// If the response included JSON in the body then it will be parsed into an
// associative array and be available via the `data` property.
$response->data; 

// If a request is forwarded then the response will contain the original URL
$response->originalUrl;

// If a request is throttled then the response will tell how many times it was
// throttled until it finally succeeded.
$response->retries;

// You can POST too. The body may be an array or a string.
$response = $fs->post('/platform/tree/persons/PPPP-PPP', [
  'body' => $personData
]);

// The SDK defaults the Accept and Content-Type headers to application/x-fs-v1+json
// for all /platform/ URLs. But that doesn't work for some endpoints that require
// the atom data format so you'll need to set the headers yourself.
$response = $fs->get('/platform/tree/persons/PPPP-PPP/matches?collection=records', [
  'headers' => [
    'Accept' => 'application/x-gedcomx-atom+json'  
  ]
]);

// You can also pass the query parameters to the HTTP methods if you don't want
// to construct the URL yourself.
$response = $fs->get('/platform/tree/persons/PPPP-PPP/matches', [
  'query' => [
    'collection' => 'records'
  ],
  'headers' => [
    'Accept' => 'application/x-gedcomx-atom+json'  
  ]
]);

// Supported HTTP methods are `get()`, `post()`, `head()`, and `delete()`. They
// all call the core `request()` method which has the same signature.
$response = $fs->request('/platform/tree/persons/PPPP-PPP', [
  'method' => 'POST',
  'body' => $personData
]);

Serialization with gedcomx-php

When the objects configuration option is set to true, the gedcomx-php library can be used for serialization from objects for requests and deserialization into objects for responses.

$fs = new FamilySearch({
    'objects' => true
});

$response = $fs->post('/platform/tree/persons', [
    'body' => new \Gedcomx\Extensions\FamilySearch\FamilySearchPlatform([
        'persons' => [ $personData ]
    ])
]);

$persons = $response->gedcomx->getPersons();

When a response body is present, it will be deserialized as either an Atom Feed or a FamilySearchPlatform object.

gedcomx-php must be installed and included separately. gedcomx-php version 3.1.2 or later is required.
