How to Add Comments to Your PHP Code for Easier Readability

Writing comments in your code is an essential practice to make your code easily readable, maintainable and understandable. It can also save you time and effort when you need to come back to the code after a while. Adding comments to your PHP code is easy to do and can help make your code much more organized and understandable.

What Are Comments?

Comments are lines of text in a code document that are not interpreted by the compiler. They are usually used to explain the purpose of a segment of code or to provide additional information. Comments can also help with debugging, as they can be used to temporarily disable lines of code or to provide notes about what is happening in the code.

Why Add Comments?

Adding comments to your PHP code is beneficial for a number of reasons. It can help to make your code more organized and easier to read. It can also help to reduce the time it takes to debug and understand the code. Furthermore, if you ever need to come back to the code after a long period of time, the comments can help to remind you of what the code is doing.

How to Add Comments

Adding comments to your PHP code is simple. All you need to do is add two forward slashes (//) before the comment in the code. For example:

// This is a comment in the code 
$variable = 'value';

You can also add comments on multiple lines. To do this, use a forward slash and an asterisk (/*) at the beginning of the comment and an asterisk and forward slash (*/) at the end. For example:

/*
 This is a multi-line comment 
 You can add as much information as you like 
*/
$variable = 'value';

Adding comments to your PHP code is a great practice for making your code more organized and easier to read and understand. It can also help to reduce the amount of time it takes to debug and maintain the code. It only takes a few seconds to add comments to your code, so make sure to add them whenever you can.
