Consistency: Blocks of well-written code always look the same and have the same indents and ways of coding, such as syntax shortcuts that use bracket placement and formatting styles consistently throughout the program. The great thing about PHP is that it really doesn’t care about tabs or indents, so you are free to create a style all your own, one that works best for you. In addition, although there may be more than one syntax for accomplishing the same goal, good coders will be consistent throughout their code with whichever method they choose. For example, as far as PHP is concerned, the following two snippets of code mean the same thing:
You should simply pick one and stick with it throughout your program.
Frequent comments: The more you use comments throughout your code, the better off you will be. Although it’s not so important in smaller, simpler programs, as your programs become more and more complex, it will be hard for you to remember what you did, where you did it, and why you did it the way you did. Detailed comments can help you find your way. Also, if you are working on a collaborative project, using comments will help your fellow code monkeys follow your logic.
The use of line numbers: Some text editors insert line numbers for you, but others do not. Text editors are discussed later in this chapter, but you should know that it is important to denote line numbers somehow in your code, if they are not provided for you, because PHP lets you know when your program generates errors, and it notifies you of the line number in which the error occurs. If you have to count the lines manually every time you encounter an error, you can imagine how time consuming and inefficient your debugging will be.
