How to write this if conditional in PHP?
<p>My variables, <code>$current</code> and <code>$row['start']</code> are in the format of <strong>2012-07-24 18:00:00</strong></p>

<p>How should I write the following ?</p>

<p><code>if ($row['start'] - $current &lt; 2 hours) echo 'starts soon'</code></p>

<p>Additionally is there a way to combine it with the below ?</p>

<pre><code>&lt;?php echo ($current &gt; $row['start']) ? 'Started' : 'Starts';  ?&gt;
</code></pre>
