<?php
$properties = array(
    title=>"Title",
    author=>"John",
    published=>1333576782
    );

$content="<p>paragraph!</p>"
block($content, $properties);

?>
Would produce:

<div class='block'>
    <div class='blockInner'>
        <h1>Title</h1>
        <span class='author'>By: John</span>
        <span class='published'>4/4/2012 at 6:01:52 PM</span>
        <p>Paragraph</p>
    </div>
</div>
