NETTUTS.com has posted the next part in their "CodeIgniter From Scratch" series today adding on more functionality to include the ability to signup for a newsletter about updates to the site.

Continuing on from Day 3, we'll expand our little application into a simple newsletter signup form. This will allow us to taker a closer look at both the email and the form_validation classes. Learn it all in this 30 minute screencast.

The tutorial is all in the screencast, but you can download the code to keep up on your own as well. There's also links to parts one, two and three to get you caught up.

On the Developer Tutorials site today, there's a new article post from Michael Ross walking you through the installation and creation of an online newsletter with the Drupal content management system.

There is a much better approach [than mass emails], and that is the use of a Web site that houses the newsletter and also limits reader access to paying subscribers. The ideal tool for creating such a site, is a content management system (CMS), such as Drupal, which is what we will be using in this tutorial. Specifically, we will explore how to use a forum for organizing the newsletter contents and allowing subscriber feedback, and also how to use a Drupal module for controlling subscriber access.

There's not really much in the way of actually installation help (that's what Drupal's documentation is for anyway), but he does talk about how it's initially set up, the subscription method and how to add an access-protected forum to the site to hold the newsletter information.

In a new post to the his blog today, Stefan Mischook takes a look at what some of the most common components of a PHP web application include.

Understanding PHP theoretically, is only the beginning of actually truly knowing it. Once you sit down and start writing code, things will seem to magically clear up as you go along.

He gives examples of web application types and talks a bit about databases, a "key part of most web applications".

The Zend Developer Zone has posted this month's Zend Newsletter for those wanting to keep up on all things Zend-ish.

They have kindly allowed me to republish the most recent issue here for your enjoyment. If you want to read it on a regular basis though you are going to have to subscribe. So take a moment and head over to MyZend, login (or register) and on the preferences panel you'll find the checkbox to subscribe. Go ahead, we'll wait.

This edition is just a preview of all of the news that Zend provides each month on its activities, events, product updates, updates to the DevZone, and offers promotions you might want to be aware of.

As Cal mentions, though, you'll need to sign up to get future releases of the newsletter - they won't be posted over on the Zend Developer Zone.

On the NorthClick blog today, there's a quick little set of hints talking about the creation of a simple ("but solid") newsletter system for your website.

He breaks it down into the individual steps you'll need to follow:

• Use a Framwork
• Queue in the database
• Use SMTP
• Check Headers
• Test it

In the step involving the database, he gives the create script you'll need to get the table set up and working. It's not so much a step-by-step tutorial with all of the needed code as it is a general look at what steps to follow when rolling your own newsletter setup.

The Zend Developer Zone quickly points out that the latest eZ Systems newsletter has been released and it includes details on version 3.8.4, updated documentation, and a few other things.

This week's newsletter brings news about an updated distribution package for eZ publish 3.8.4, new documentation for eZ publish upgrades and new information about eZ platform development. The newsletter also includes the weekly forum watch and an update about the current bug fix status.

They cover the update to eZ publish, the "Upgrade" section in the documentation, new advancements concerning eZ platform, and some interesting discussions going on over in their forums.
