brackets in php templates
<p>I have a script, and now it's the perfect time to have an option to change <code>theme</code> templates. </p>

<p>I was looking forward to store these files in <code>php</code> files, or html files. with <code>CSS</code> file. I looked over some codes and I found that they use brackets to refer to the variable.</p>

<p>Here's an example of a template block: </p>

<pre><code>&lt;div class='block_div'&gt;
&lt;center&gt;{title}&lt;/center&gt;
{content}
&lt;/div&gt;
</code></pre>

<p>I know that I can use <code>PHP</code> vars usering <code>&lt;?=$var;?&gt;</code>. However, I think the one above is better, and I looked over the web to find anything about it but I couldn't. </p>

<p>My Question is how I can use these brackets in my php or html code. to let the user changing the template only not the code!</p>
