Are these two lines of PHP different?
<p>I'm looking through a code base. This is one of the lines.</p>

<pre><code>require_once( dirname(__FILE__) . '/a_script.php' );
</code></pre>

<p>I'm considering rewriting it as:</p>

<pre><code>require_once( './a_script.php' );
</code></pre>

<p>Are those two lines of code any different?</p>
