Is it possible to disjunct two require_once statements with OR operator to use the latter as fallback?
<p>Is there a way to perform double <code>require_once</code> statement where the second one as a fallback if the first one fails?</p>

<p>For example: I can do this</p>

<pre><code>mysql_query() or die("Boo");
</code></pre>

<p>Could I do:</p>

<pre><code>require_once('filename') or require_once('../filename');
</code></pre>

<p>If one fails it reverts to the other?</p>
