Reddit PHP SDK

The Reddit SDK is a wrapper around the Reddit OAuth 2 API: http://www.reddit.com/dev/api/oauth

Initiating Your Login Session

Before making requests to any of the methods of the Reddit SDK, you first need to instantiate a new OAuth 2 session by using your client id and client secret. You may obtain these keys by creating a new app at https://ssl.reddit.com/prefs/apps and posting the key and secret into the appropriate sections in config.php.

require_once("reddit.php");
$reddit = new reddit();

How to Build the Fullname Parameters

Frequently within these SDK methods, you will see parameters that reference the fullname or id of a message, comment, account, etc (e.g. values like t4_1kuinv). The Reddit API uses identifiers that consist of a prefix to identify the type of the fullname (e.g. t3_ or t4_), and the identifier of that thing (e.g. 1kuinv). To build a fullname of a thing, you must take its id, and add the prefix to the front.

The following is a list of prefixes that the Reddit API uses, and the type of thing that they reference:

  • t1_ : Comment
  • t2_ : Account
  • t3_ : Link
  • t4_ : Message
  • t5_ : Subreddit
  • t6_ : Award
  • t8_ : PromoCampaign

SDK Methods

Once you are authenticated, you may then make requests to any of the methods in the SDK.
