PHP Comments

A comment is a part of the coding file that the programmer does not want to execute. Rather, the programmer uses it to either explain a block of code or to avoid the execution of a specific part of code while testing.

PHP supports several ways of commenting:

Single Line Comments

<?php
// This is a single-line comment
# This is also a single-line comment
?>

Multiple-Line Comments

<?php
/*
This is a
multiple line
Comment.
*/
?>
