Taking the Zend Certified PHP Engineer Exam: My Story
Thinking about taking the Zend Certified PHP Engineer Exam? Before you do, see what David Fells experienced when he recently took the test and see what you should be ready for and what not to waste your time (or money) on.

Quick Introduction to PHP 5
The groundbreaking release of PHP 3 in 1997 revolutionized the way in which Web sites are developed, and made it possible for everyone to create simple, yet powerful Web applications. PHP 4 took PHP much further by introducing the Zendģ Engine, pushing the performance of PHP through the roof, and allowing it to be more extensible than ever before.

PHP SOAP Extension
This article describes the new SOAP extension for PHP. It is intended for PHP developers who want to write their own Web Services servers, or use SOAP to access existing ones. It assumes some familiarity with Web Services, SOAP, and WSDL (Web Services Description Language).

Improving Performance
Your web presence is growing! Traffic and usage are escalating and you have to maintain a superior level of performance. The state of growth unfolds many opportunities but it also holds challenges as a result of change. Not only does performance affect your operating costs, it also reflects directly on the end-user experience. The marketing and sales departments are probably saying that happier users directly increase sales.

PDFs with PHP part 2
This tutorial is intended for the PHP programmer who needs to incorporate PDF generation in a script without using external libraries such as PDFlib (often unavailable due to licensing restrictions or lack of funds). This tutorial is the second of two parts, and builds on what was covered in the first part. Therefore, if you have not yet gone through Part 1, you are advised to do so (or at least read through it), before going through this tutorial (Part 2). Apart from what was dealt with in Part 1, no knowledge of PDF file structure is required to understand this tutorial, as all references are explained.

PDFs with PHP part 1
This tutorial is intended for the PHP programmer who needs to incorporate PDF generation in a script without using external libraries such as PDFlib (often unavailable due to licensing restrictions or lack of funds). This tutorial will cover only the basics, which hopefully will give you a good start. PDF has a vast set of features and possibilities which can not be covered in a short tutorial. If you need more than what is covered here, you might want to look at some similar yet more complete solutions available, such as the excellent work done by Olivier Plathey on the FPDF class (http://fpdf.org), on which this tutorial is based. Of course, you may wish to take your own route and for that there is also the PDF reference (be warned: itís 1,172 pages!) Basic familiarity with using PHP classes is assumed. Knowledge of PDF file structure is not required, as all references are explained.

Build Database Interfaces
This article is about using and building Database Interfaces (DB interfaces). DB interfaces make application development faster and easier. This is accomplished by relocating scattered DML (Insert, Update, Delete) statements into a single shared tool, the Class. A Class encapsulates data post processing, integrity, and security into a single tool that can be accessed throughout the application.
