Comments

PHP allows you to comment your code using three methods:

# This is a single line comment.

// This is also a single line comment.

/* This is a
multi-line
comment*/

For example: comments.php


<html>
<head>
<title>comments.php</title>
</head>
<body>
<?php
/*
Date: 01/31/2006
Programmer: Manuel Chagoyan
Purpose: To add up the amount owed to me by my students.
*/

$number1=10; //This is the $10 bucks Jenah owes me.
$number2=15; //This is the $15 bucks David owes me.
$number3=5;   #This is the 5 bucks Ethan owes me (plus interest).

$total=$number1+$number2+$number3; //This creates a variable to hold total owed.

/*
This section prints to the browser.
It concatinates text, html, and php
variable output.
*/


print("<p>The sum of the numbers is ".$total."</p>");

print("I have ".($number1+$number2+$number3)." dollars!");

?>
