Akismet Client Library

Introduction

Provides a straight-forward way of using the Akismet anti-spam service in any-old PHP application.

Installation & Requirements

Requires PHP ~8.0 || ~8.1 || ~8.2

The library does not include an HTTP client, so if your project does not already have a PSR-18 HTTP Client installed, you will need to install one in order to use it. There are many HTTP clients to choose from, for example the popular libraries Guzzle or HttpPlug.

The library also requires that you have a PSR-17 (HTTP Factories) library installed, again, you can find implementations on Packagist and I personally favour laminas/laminas-diactoros.

Basic Usage

Construct a client

Once you have the requisite HTTP related libraries installed, they should become discoverable with the shipped discovery library. Provide an Api key, and the default website address that you will be operating with to the constructor, and you’ll have a ready-to-use client:

Comment Parameters & Checking Content

The primary concern of the library is to check requests such as comments and form submissions to ascertain whether the content is "Spam" or "Ham".

The Akismet API has a number of parameters available to improve the accuracy of the check which have been encapsulated into an immutable value object \Gsteel\Akismet\CommentParameters.

If you are familiar with the parameter names, you can pass in an array to the constructor of this object, otherwise you can call various methods to build an object to include all the information you wish to provide.

There are a considerable number of additional arguments and methods available that can be used to provide as much context as possible to the API, there is also a named constructor that is useful in an environment that utilises PSR-7 Messages:

Submitting False Positives or False Negatives

Submitting content that was incorrectly classified as Spam can be achieved by sending the same payload used in check() to the method submitHam(). Conversely, you can submit incorrectly classified Ham as actual Spam with submitSpam():

You can serialise and un-serialise a Result from the clients check() method to a JSON string:

Coupled with your own method of identifying a specific request, you could create a mechanism to store the result in order to submit it as ham or spam based on user feedback.

Error Handling

All errors implement \GSteel\Akismet\GenericException so it is possible to catch any errors thrown by the library with a single type. Notable concrete exceptions include:

• ApiError - Indicating that an api request failed because of an invalid key for example
• HttpError - A failure to communicate with the Akismet via HTTP
• InvalidRequestParameters - Required values missing, or invalid values given to CommentParameters

PSR-11 Containers

A factory is shipped in \GSteel\Akismet\Container\ClientDiscoveryFactory that can be wired up in your DI container of choice that leverages Http Discovery to inject Http clients and factories etc.

It assumes that the container will return an array or something implementing ArrayAccess by asking for config It further assumes that this configuration structure contains the following information:
