PHP Comments

Comments are notes about the code, they explain the function performed by a specific code.

Comments are extremely important for you and for other people who will use your code. It is a good idea to get used to comment your code as soon as possible. When you will be working on someone else's code, or even your own code after a long time, comments will save your life.

Browsers and servers will ignore comments. In PHP you can use double shash (//) or hash mark (#) syntax for single line comments, slash asterisk (/* … */) syntax for multiline comments.

<?php 
//this is a single line comment (C++ style)

#this is another way to write a single line comment (Unix shell style)

/*
 THIS
IS
A
MULTILINE
COMMENT (C style)
*/

?>
