Foursquare API Client by TheTwelve Labs

A(nother) PHP Foursquare API client
https://developer.foursquare.com/docs/

Installation

Composer is currently the only way to install the foursquare client into your project.

Create your composer.json file

  {
      "require": {
          "thetwelvelabs/foursquare": "0.2.*"
      }
  }

Download composer into your application root

  $ curl -s http://getcomposer.org/installer | php

Install your dependencies

  $ php composer.phar install

Usage

Select your preferred HTTP Client (CurlHttpClient is the default)

  $client = new \TheTwelve\Foursquare\HttpClient\CurlHttpClient($pathToCertificateFile);

Select your preferred Redirector (HeaderRedirector is the default)

  $redirector = new \TheTwelve\Foursquare\Redirector\HeaderRedirector();

Note: The redirector is optional and is only needed if you need Foursquare authentication

Instantiate the API Gateway Factory

  $factory = new \TheTwelve\Foursquare\ApiGatewayFactory($client, $redirector);
  
  // Required for most requests
  $factory->setClientCredentials('CLIENT_ID', 'CLIENT_SECRET');

  // Optional (only use these if you know what you're doing)
  $factory->setEndpointUri('https://api.foursquare.com');
  $factory->useVersion(2);
  $factory->verifiedOn(new \DateTime());

Begin authentication with Foursquare

  $auth = $factory->getAuthenticationGateway(
      'https://foursquare.com/oauth2/authorize',
      'https://foursquare.com/oauth2/access_token',
      'YOUR_REDIRECT_URL'
  );

  $auth->initiateLogin();

Foursquare redirects the user back to you after a successful login

  $code = $_GET['code'];

  // You should do some input sanitization to $code here, just in case  
   
  $token = $auth->authenticateUser($code);

Update the API Gateway Factory with your OAuth token

  $factory->setToken($token);

Get an instance of an endpoint gateway

  $gateway = $factory->getUsersGateway();

Get data from Foursquare

  $user = $gateway->getUser();

Search venues

  $gateway = $factory->getVenuesGateway();

  $venues = $gateway->search(array(
    'll' => '40.727198,-73.992289',
    'query' => 'Starbucks',
    'radius' => 1000,
    'intent' => 'checkin'
  ));

Working With Symfony / Silex

If you're working with Symfony or Silex, you can use the Symfony HttpClient and Redirector

  $client = new \TheTwelve\Foursquare\HttpClient\SymfonyHttpClient();
  $redirector = new \TheTwelve\Foursquare\Redirector\SymfonyRedirector();

If you're working with Silex, there is a Service Provider available at https://github.com/chriswoodford/FoursquareServiceProvider

Using the CurlHttpClient

If you're using the CurlHttpClient, you will probably want to include the cacert.pem file that can be found at http://curl.haxx.se/docs/caextract.html

You can add this as a dependency in your composer file. Your composer.json might look something like this:

  {
      "require": {
          "thetwelvelabs/foursquare": "0.2.*",
          "haxx-se/curl": "1.0.0"
      },
      "repositories": [
          {
              "type": "package",
              "package": {
                  "name": "haxx-se/curl",
                  "version": "1.0.0",
                  "dist": {
                      "url": "http://curl.haxx.se/ca/cacert.pem",
                      "type": "file"
                  }
              }
          }
      ]
  }

You will be able to find the cacert.pem file in vendor/haxx-se/curl/cacert.pem
