How To Comment PHP Program Lines
How to comment PHP code is one of the most important things you must know when programming in PHP. The first step is understanding that PHP does not have a built in comment facility. Comments in general are generally ignored by the script engine, meaning that the script engine will not try to run any text written within a comment. In simple terms, all code should be written very clearly and cleanly so that it is obvious what the code is doing. If the syntax of the PHP code is not clear then the resulting output will not be clear either. If this happens then the code is likely to have problems.
Most common styles for how to comment in PHP involve the use of a semicolon at the end of a single line comment, or one or more commas depending on the nature of the comment and the PHP code that have caused it. However, this all depends on the situation. Some programmers prefer to use a single line comment, and others prefer to use commas. The best way to comment in PHP is of course to use both, but this is beyond the scope of this article. We will however discuss the different options that are available to you.
You can create a number of different style guides for how to comment PHP code. They are in fact not hard to create at all, and you can certainly customize them to suit your needs. If you want to create a style guide then first create an outline of the style rules you wish to follow. Next, copy and paste the rules from a web page that implements the style you have outlined. Now all you have to do is fill in the details.
One of the options that you have for how to comment PHP programs is to use a single-line comment. This means that you either include the entire comment as a single line, or you put a closing comment within the PHP code. This option is very useful when you are commenting out a PHP example or rewrite an existing PHP script. The reason that you would want to use a single-line comment when dealing with an example/rename is that if you use multiple lines the indentation of the lines will be different. Using a single-line comment allows you to maintain the indentation throughout the comment.
The second style comment option that is available to you is a multi-line comment tag. A multi-line comment tag looks just like a regular PHP comment, except it also includes a semicolon instead of a colon. This allows you to write multiple comments in a single statement, and helps maintain the spacing between statements the same way that single-line comments do. This option is useful when you are coding an application, as the multiple lines can be used to create error messages or to help maintain the spacing between statements.
The third option that you have is the double-spacing comment tag. If you use this option in your how to comment the scripts you will be creating two single line comments instead of one. This is useful for when you are commenting out an instance of PHP in order to create API documentation. This method is useful for when you are coding a function, but it does not work well when you are commenting out an instance of that function.
The fourth option that is available to you when it comes to how to comment the code is the multiple-space style comments. This is not really part of the PHP coding language itself, but rather a common configuration for many text editors and even the web page editor that you are working with. This option allows you to create single line comments, as well as multiple-space style comments. The multiple-space style comments allow you to create a sort of manual comment which allows you to provide more descriptive syntax for your php code.
These four options are the ones that can be used when you are learning how to comment the code. The important thing is to remember that as long as you know what you are doing, and that you stick to using single-line and multi-line comments only, you should not have any problem at all editing your php code. In fact, it can even be easier than writing your own code in the first place. That being said, if you need to learn how to comment the code properly, there are plenty of tutorials available online that can help you do it.
