Comments in PHP

Comments are lines of code in a program that do not get executed. They help developers understand what each step in the program does, making it easier to work on the code in the future. Comments can be single-line or multi-line.

Types of Comments in PHP

  1. Single Line Comments In PHP, single-line comments can be written in two ways: using // or #. Example: Single Line Comments File: comment.php
   <?php  
     // This is a single line comment
     $x = "This is single line Comment";
     # This is also a comment
     echo $x;
   ?>

Output:

   This is single line Comment
  1. Multi-Line Comments Multi-line comments start with /* and end with */. These are useful for commenting out larger blocks of code or writing detailed explanations. Example: Multi-Line Comments File: comment2.php
   <?php  
     $x = "This is multi line Comment"; 
     /* This is a multi-line comment
        and it can span multiple lines
        for detailed explanations */  
     echo $x;
   ?>

Output:

   This is multi line Comment

Why Should We Use Comments?

  • Easier Maintenance: When working on a project over time, comments help you understand what you did and why, making it easier to update the code.
  • Collaboration: Comments are essential when other programmers work on your code, allowing them to grasp the logic and purpose of different parts quickly.
  • Coding Standards: Writing comments reflects good coding practices and enhances the overall standardization of the code.
  • Improves Readability: Well-commented code is easier to read and understand, making it accessible for anyone revisiting the code, whether it’s you or another developer.

Using comments effectively makes your code more manageable and helps maintain a professional coding standard.
