Exercises for Programmers part 1

Here’s a supplemental video to reinforce the ideas for these first exercises.

A utility function

function formatCode($code) {
	echo "<code class='show-code'>";
		echo '<pre>';
			print_r($code);
		echo '</pre>';
	echo '</code>';
}

This will be helpful!

saying-hello.php

<?php
	/* initializing the data */
	$name = "Bobbo head";

	/* handing user input */
	$formSubmitted = isset($_POST["submitted"]);

	if ($formSubmitted) {
		$name = $_POST["firstName"];
	}

	/* calculations */
	$greeting = "Hello, $name, nice to meet you!";
?>

<form method='POST'>

	<field>
		<label for="fn">What is your first name?</label>
		<input id="fn" type="text" name="firstName">
	</field>	

	<button type="submit" name="submitted">Submit</button>

</form>

<output>
	<!-- feedback -->
	<p><?=$greeting?></p>
</output>

There are a few loose ends to tie up here…

Do you know what they might be? Have you tried it out in all of the scenarios that might happen?
