How to use custom PHP templated system
<p>We are building an app and would like to separate html part from code(php) part, how can we use following template file with php?</p>

<pre><code>&lt;h1&gt;{$heading}&lt;/h1&gt;
&lt;p&gt;{$content}&lt;/&gt;
</code></pre>

<p>And php code as following...</p>

<pre><code>&lt;?php
$heading = $row['heading'];
$description = $row['content'];
?&gt;
</code></pre>

<p>how can we inlclude tpl file and use it? thanks.</p>
