Including files from a directory
<p>Does (a) have any benefits over (b)?</p>

<p>a) <em>A function that returns the path to the file.</em></p>

<pre><code>include util("array");

function util($name)
{
    return PATH."utils/$name.php";
}
</code></pre>

<p>b) <em>A function that directly includes the file.</em></p>

<pre><code>util("array");

function util($name)
{
    include PATH."utils/$name.php";
}
</code></pre>
