In this PHP tutorial we will study about different kinds of comments supported by PHP, the differences among all those comments. Examples will exemplify each type.

PHP Comments:

Most of the popular languages (C, C++, Unix) uses same kind of comments, single line (//) and more than one line comments (/* */) and along with these Unix like comment '#' is also supported by PHP.

Single line comments ( // ) is used to make a single line or a block inactive. Similarly the task of # is the same.

Double line or multiple line comments are used when large block is to be commented.

Example:

<?php

//This is a single comment

#This is Unix style comment

/*

* This

* is

* Multiple

* line

* comment

*/

?>

 

Note: Since the above example has only comments, no output will be generated
