Comments in PHP

Comments in PHP

Comments in any programming language is used to discribe code and make simple to understand other programmer and it is ignore by compiler or interpreter.

PHP supports single line and multi line comments. PHP comments are similar to C/C++ and Perl style (Unix shell style) comments.

PHP Single Line Comments

There are two ways to use single line comments in PHP.

• // (C and C++ style single line comment)
• # (Unix Shell style single line comment)

<?php

// this is C++ style single line comment  
# this is Unix Shell style single line comment  
echo "Welcome to PHP single line comments";

?>

PHP Multi Line Comments

In PHP, we can comments multiple lines also. To do so, we need to enclose all lines within /* */. Let's see a simple example of PHP multiple line comment.

<?php

/* 
Anything placed 
within comment 
will not be displayed 
on the browser; 
*/  
echo "Welcome to PHP multi line comment";  

?>
