PHP SKF Framework Released To Public
Over the years, we here at PHPRO.ORG have been using a light weight framework p ut together to ease the suffering of the one-size-fits-all frameworks that pollute the PHP space. As time has passed, others have adopted the SKF Framework for thier own, and customer sites. Now, due to popular demand and threats, we are making this freely available to the public. So, what makes this framework any different? The ease of creating modules, the ability to use whatever classes you are familiar with, namespace support, and not least, it is a light weight framework. There are no dependencies, you can use whatever libs, db abstractions, mail classes, whatever. The greatest benefit of the SKF Framework is it just works out-of-the-box. No initial configuration is needed to the framework. Drop it in your web root and it just works! Check it out now https://bitbucket.org/kevinwaterson/skf.

When Tutorials Attack
In a recent series of tutorials released by SUN Developers Community a few notable omissions glared back from the web page. Like many PHP tutorials that pollute the web, there was a little, or no error checking, or error handling in the provided code examples. These omissions are paramount to development in any language, particularly for those who's livelihood relies on the strength of perceived enterprise readiness of the technology. To the new comer, these tutorials are the source of truth, and quality code examples are required if these new comers are going to produce quality code.

Creating Secure Passwords
The greatest security risk to password protection, is the user who created the password. Most developers have at sometime needed to create a system where passwords were required. Password protection comes in various implementations, from accessing a single file, or gaining entry to a system, or administration panel. The protection provided by passwords however, is only as secure as the password itself. A password that is predictable, or easy to guess can leave your security model less than adequate. However, it is not just end users who are at fault, as there is plenty of finger pointing at developers who permit insecure passwords to be used.

Embedding PHP In CSS
Perhaps one of the most frustrating aspects of using PHP with websites, is getting variables into CSS. Having variables stored in an ini file, config file or even a database can make the updating of the look and feel of a site simple, however, CSS files, by default, do not parse PHP. Of course, the web server could be told to parse CSS as PHP in the same way it does for HTML. AddType application/x-httpd-php .css With the addition of the above line in httpd.conf or in a .htaccess, the web server will now parse PHP code that is within the CSS files. This is one solution, but a better method may be at hand.

Difference Between isset empty is-null
Quite often in code reviews I have come across code that checks for empty or null values, or if a variable is set. Many of these checks fail as the wrong function is being used to assert the correct value. While it is important to be checking values, it is equally important to understand the difference between the different methods of checking and testing values for empty, null, or if they are set.

SUN Sets On MySQL Monty Leaves SUN
The sale of MySQL to SUN was greeted with mixed sentiment by the open source community as was reported on PHPRO in This article.

Now however, things have changed.

Zend Framework Example Site
The Zend Framework has now attracted a small community of developers and more and more new comers are attracted to it. The Zend Documentation is plentiful, yet vague. Without any real guidance or specific examples to get a site up and running. This example site hopes to introduce the newcomers to Zend Framework in a friendly way, by providing a simple modular site layout and can have the newcomer up and running in minutes, rather than the long hard yard of sifting through docs which might as well be hieroglyphics to the those new to the framework. This is release 0.0.1 of the example site, with new additions in the planning and user feedback and requests welcomed.
