Almost all the programming languages allow you to add comments to your code. Comments are read only by humans - the interpreter doesn’t evaluate them. Comments serve as notes for those who wrote them and other developers. There are two types of comments in php:
Single line comments start with
//. Whatever follows after will not be evaluated or executed.
A comment can take up the whole line:
<?php // For Winterfell!
or can follow some code on the same line:
<?php print_r('I am the King'); // => For Lannisters!
Multiline comments start with
/* and end with
*/. Each line between them should start with a
<?php /* * The night is dark and * full of terrors. */ print_r('I am the King');
Create a single line comment with the folowing text:
You know nothing, Jon Snow!.
Comment — A comment is just a text and it doesn’t affect program execution. Programmers use it to add notes for themselves and for their colleagues
