Convert date to day name e.g. Mon, Tue, Wed
<p>I have a variable that outputs the date in the following format:</p>

<pre><code>201308131830
</code></pre>

<p>Which is 2013 - Aug - 13 - 18:30</p>

<p>I am using this to retrieve the day name but it is getting the wrong days:</p>

<pre><code>$dayname = date('D', strtotime($longdate));
</code></pre>

<p>Any idea what I am doing wrong?</p>
