Introduction

This is a simple little PHP5 class that enables you use the Akismet anti-spam service in your PHP5 application.

Download

Check out the git repository:

git clone git@github.com:achingbrain/php5-akismet.git

Installation

Once you have cloned the repo (see Download, above) copy the file at src/main/php/net/achingbrain/Akismet.class.php to somewhere accessible to your scripts. Use include or a derivative to import it into your script.

Alternatively if you are running a version of PHP greater than 5.3, grab the phar file and use the following code:

<?php
	include 'phar:///path/to/php5-akismet-0.5.phar/net/achingbrain/Akismet.class.php';
?>

Documentation

See the PHPDocs.

Usage

Before you can use Akismet, you need a WordPress API key (they are free and getting one takes about five minutes). Once you have one, take a look at the code below:

$WordPressAPIKey = 'aoeu1aoue';
$MyBlogURL = 'http://www.example.com/blog/';

$akismet = new Akismet($MyBlogURL ,$WordPressAPIKey);
$akismet->setCommentAuthor($name);
$akismet->setCommentAuthorEmail($email);
$akismet->setCommentAuthorURL($url);
$akismet->setCommentContent($comment);
$akismet->setPermalink('http://www.example.com/blog/alex/someurl/');

if($akismet->isCommentSpam())
  // store the comment but mark it as spam (in case of a mis-diagnosis)
else
  // store the comment normally

That's just about it. In the event that the filter wrongly tags messages, you can at a later date create a new object and populate it from your database, overriding fields where necessary and then use the following two methods to train it:

$akismet->submitSpam();

and

$akismet->submitHam();

to submit mis-diagnosed spam and ham, which improves the system for everybody. See the included documentation for a complete run-down of all available methods.

Changelog
