<!-- 1 -->
<li>Create a directory called <b class="copyText"><?=$evaluationName?></b> in your <b><?=$dataFolder?><?=$dirSep?><?=$courseNumber?></b> directory. We will use it for all work performed in this lab.</li>
<!-- 2 -->
<li>Code a PHP file for include/require:
<ol>
<li>Create a PHP file named <b class="copyText">application.php</b> in the <b><?=$evaluationName?></b> directory and open it in an editor.</li>
<li>Write a function called <b class="copyText">beginPage</b> which takes one parameter named <b class="copyText">$title</b>.
<br><span class="note">The purpose of this function is to output the beginning of an html document.</span>
<ol>
<li>Code the beginPage function so it outputs the beginning code of an html document with the following:
<ol>
<li>The HTML 5 DOCTYPE: <span class="html copyText"><!DOCTYPE html></span>.</li>
<li>An start html tag with the <span class="highATT">lang</span> attribute set to <span class="highVAL">en</span>: <span class="html copyText"><html lang="en"></span>.</li>

<li>Call the <b class="php">beginPage</b> function with a parameter of <b class="copyText">Create a file</b>.</li>
<li>Open a file named <b class="copyText"><?=$saveFilename?>_Text.txt</b> so it will create the file if it does not exist or truncate it if the file exists.</li>
