The Importance of Planning
Why You Should Read This Section
Even if you’re already a professional programmer familiar with PHP, we encourage you to read the following
sections, as they cover the basics for successful development. If you’re already familiar with the
discussed topics, take the time to browse through the text anyway; you might discover new information—
new views of problems, new approaches, new solutions. The more you know about approaching different
aspects of your future projects, the better you’ll be at nailing down the critical fragments and handling
them in a superior way. Many of the following sections also discuss topics that are more questions of
belief than commonly accepted rules. We’d like you to trust us as professional developers and rely on our
experience before abandoning the content—it will pay later on.
Before diving into PHP-specific issues, let’s start from a wider point of view. Some
issues apply to application development in general, regardless of which language you’re
using and on what platform you’re developing.
When working on a professional project, it’s very important that you think about
what you’re doing. Know your enemy—never underestimate him. Although your project
isn’t really an enemy, the point still applies. Know all your project’s specifications, its
target platform(s), its users, and never underestimate the significance of small problems
that you haven’t evaluated completely before moving on to other topics.
Judging from our experience, planning takes at least 50% of the development time;
the bigger the project, the more thoroughly you should develop its outlines.This principle
applies to contacting your customers and working closely with them on defining
an overall project outline, as well as talking with your developers about defining a
coding outline.The less effort you spend on consistency and maintainability, the
sooner you’ll run into problems when reopening old files and trying to fix bugs or
add new features.
