PHP Comments

PHP Comments are used to describe any line of code or program, But it can also be used to hide your code. Code hiding means, the code will not be executed.

Not only this, it will also help other developers to understand your code easily. And it also helps you because sometimes you forget why you wrote this code.


Like other languages, PHP also supports single-line comments and multiple line comments.

Comments are not executed. That means you can’t see comments in browsers.


Types of PHP Comments

There are two types of comments –

  • Single-Line Comments
  • Multiple Line Comments

Single-Line Comments

In PHP, there are two ways to add single-line comments –

  • Using double forward-slash //
  • Using the hash sign #
<?php
  //This is a single line comment
  #This is another single line comment
  echo "You can't see comments in browsers";
?>
Browser Output
You can’t see comments in browsers

Multiple Line Comments

In PHP, Multiple Line Comments start with /* and ends with */

<?php
/* Multiple
Line
Comments */
echo "Hello World!";
?>
