3539	Separating program and artwork in PHP - easier maintainance, and better for the user I can code reasonably well. But my graphic design sucks. And both skills are needed for even a simple web data entry form, or a small application. Using the PHP "bull at a gate" approach, both business logic (the code) and look and feel (the graphic art stuff) can be written into a single file, but ...	2011-12-06
3454	Your PHP website - how to factor and refactor to reduce growing pains As your project grows ... what do you change? In an ideal world, you would know exactly what you were coding before you started, and write the full job to spec to last for many years. This isn't an ideal world, though. Our web site has changed over the years - we now have "version 8" (See [here] to ...	2011-09-24 (longest)
2221	Adding a newsfeed for your users to a multipage PHP application As I wrote it, I realised this was turning into rather a long article, but never mind. It shows the major new components added to a "4 layer model" application I was working on the weekend before last to add in a newsfeed for logged in users to which they can contribute, together with a headlines-only ...	2009-06-07 (longer)

On Saturday and Sunday, I demonstrated ...	2009-05-26
2174	Application design in PHP - multiple step processes When you're putting together a multiple step process in PHP (and that could be anything from a forum to an ordering system), you should bare in mind that each of the program elements will be the 'intermediate' step that takes you from one display to the next ... and that you can't be sure when page "X" ...	2009-05-11
1766	Diagrams to show you how - Tomcat, Java, PHP I like to work with a flipchart occasionally, and I have been doing so quite a bit this week, which is a week that I'm giving a wide ranging web server deployment course under Linux, covering both LAMP / PHP technologies, and Tomcat / Java too. Why do I like using a flipchart? Because it encourages ...	2008-08-24 (longest)
1716	Larger applications in PHP I've just finished a two day PHP techniques course - a subject that's tremendous fun to present, and a huge benefit to the delegates, as PHP programs can be written with great beauty, maintainability and expandability (like a Picasso) or they can be an unmaintainable mess (making the dog's dinner look ...	2008-07-23
