Hardsetting Data to Check a Script

In order to test a script, it is often most beneficial to hardset variables so that they contain known values.

We will use the area-of-a-triangle problem for this demonstration.

A PHP Script to Handle Hardset Information

The following code should be saved in a file called trihardset.php in ~YOURID/public_html/test_php/.

<!-- trihardset.php -->
<html>
<head>
<title>Calculating the Area of a Triangle: Result</title>
</head>
<body>
<?php
// This script illustrates how to process information
// hardset in a script for testing purposes

// Hardset the dimensions dimensions $b (base) and $h (height)
// of the triangle
$b = 5;
$h = 7;

echo "<h1 align=\"center\">Calculating the Area of a Triangle: Result</h1>\n";
// Print the base
echo "<p>b is $b.\n";

// Print the height
echo "<p>h is $h.\n";

// Calculate and print result
$A = $b * $h / 2;
echo "<p>The area of a triangle with a base of $b and a height of $h is $A.\n";
?>
</body>
</html>

Notes

Take note of the documentation in this and other files. Since you will be copying your code from one file to another, or just making copies of a file, which you then modify, it is important to keep track of the names of the files you are working on.
