Exercises for Programmers part 1

Last updated: October 24, 2022

Introduction

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

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

    This will be helpful!

  2. 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?
