Instagram PHP API

About

A PHP wrapper for the Instagram API.
This is my first PHP class, so please bear with me.
Feedback or bug reports are appreciated.

Requirements

• PHP 5.2.x or higher
• cURL
• Registered Instagram App

Get started

Register your application with Instagram, and receive your OAuth client_id and client_secret.
Take a look at the uri guidlines before registering a Redirect URI.

A good place to get started is the example App.

Initialize the class

<?php
    require_once 'instagram.class.php';
    
    $instagram = new Instagram(array(
      'apiKey'      => 'YOUR_APP_KEY',
      'apiSecret'   => 'YOUR_APP_SECRET',
      'apiCallback' => 'YOUR_APP_CALLBACK'
    ));
    
    echo "<a href='{$instagram->getLoginUrl()}'>Login with Instagram</a>";
?>

Authenticate user (OAuth2)

<?php
    // Grab OAuth callback code
    $code = $_GET['code'];
    $data = $instagram->getOAuthToken($code);
    
    echo 'Your username is: ' . $data->user->username;
?>

Get user likes

<?php
    // Store user access token
    $instagram->setAccessToken($data);
    
    // Get all user likes
    $likes = $instagram->getUserLikes();
    
    // Take a look at the API response
    echo '<pre>';
    print_r($likes);
    echo '<pre>';
?>

All methods return the API data json_decode() - so you can directly access the data.

Available methods

Setup Instagram

new Instagram(<array>/<string>);

array if you want to authenticate a user and access its data:

new Instagram(array(
  'apiKey'      => 'YOUR_APP_KEY',
  'apiSecret'   => 'YOUR_APP_SECRET',
  'apiCallback' => 'YOUR_APP_CALLBACK'
));

string if you only want to access public data:

new Instagram('YOUR_APP_KEY');

Get login URL

getLoginUrl(<array>)

getLoginUrl(array(
  'basic',
  'likes'
));

Optional scope parameters:

Scope	Legend	Methods
basic	to use all user related methods [default]	getUser(), getUserFeed(), getUserFollower() etc.
relationships	to follow and unfollow users	modifyRelationship()
likes	to like and unlike items	getMediaLikes(), likeMedia(), deleteLikedMedia()
comments	to create or delete comments	coming soon...

Get OAuth token

getOAuthToken($code, <true>/<false>)

true : Returns only the OAuth token
false [default] : Returns OAuth token and profile data of the authenticated user

Set / Get access token

Stores access token, for further method calls:
setAccessToken($token)

Returns access token, if you want to store it for later usage:
getAccessToken()

User methods

Public methods

• getUser($id)
• searchUser($name, <$limit>)

Authenticated user methods

• getUser()
• getUserLikes(<$limit>)
• getUserFeed(<$limit>)
• getUserMedia(<$id>, <$limit>)
  • if an $id isn't defined, it returns the media of the logged in user

Sample responses of the User Endpoints.

Relationship methods

Authenticated user methods

• getUserFollows(<$id>, <$limit>)
• getUserFollower(<$id>, <$limit>)
• getUserRelationship($id)
• modifyRelationship($action, $user)
  • $action : Action command (follow / unfollow / block / unblock / approve / deny)
  • $user : Target user id

<?php
    // Follow the user with the ID 1574083
    $instagram->modifyRelationship('follow', 1574083);
?>

Sample responses of the Relationship Endpoints.

Media methods

Public methods

• getMedia($id)
• getPopularMedia()
• searchMedia($lat, $lng, <$distance>)
  • $lat and $lng are coordinates and have to be floats like: 48.145441892290336,11.568603515625
  • $distance Distance in meter (max. distance: 5km = 5000) (radial?)

All <$limit> parameters are optional. If the limit is undefined, all available results will be returned.

Sample responses of the Media Endpoints.

Tag methods

Public methods

• getTag($name)
• getTagMedia($name)
• searchTags($name)

Sample responses of the Tag Endpoints.

Likes methods

Authenticated user methods

• getMediaLikes($id)
• likeMedia($id)
• deleteLikedMedia($id)

How to like a Media: Example usage Sample responses of the Likes Endpoints.

Further endpoints

It's planned to extend the class with new methods. Let me know, if you think, that one of the missing endpoints has priority.

Missing Endpoints:

Comments, Locations, Geographies

For all parameters in the configuration array exists a public setter and getter method.

Pagination (alpha)

This feature is still in development, but you can test it on the dev branch: Pagination documentation.

Samples for redirect URLs

Registered Redirect URI	Redirect URI sent to /authorize	Valid?
http://yourcallback.com/	http://yourcallback.com/	yes
http://yourcallback.com/	http://yourcallback.com/?this=that	yes
http://yourcallback.com/?this=that	http://yourcallback.com/	no
http://yourcallback.com/?this=that	http://yourcallback.com/?this=that&another=true	yes
http://yourcallback.com/?this=that	http://yourcallback.com/?another=true&this=that	no
http://yourcallback.com/callback	http://yourcallback.com/	no
http://yourcallback.com/callback	http://yourcallback.com/callback/?type=mobile	yes

If you need additional informations, take a look at Instagrams API docs.

Example App

The small App, which is located in the example/ folder, helps you to get started with the class.
Its whole code is documented and will take you through all steps of the OAuth2 process.
The great Instagram Sign In button is designed by Murat Mutlu.

A short tutorial about how to build an Instagram login with my class has been published at 9lessons.
