content rotator using php (partial content only)

[artist19]

I use the code below to insert a partial content block on the web page (index.php). It is random but I would like to add a code to make it a content of the day for 365 days or 31 days. How can I add the code (date) to this below? Thanks much.

 

 

<?php

$content = array("s/skill.php","h/help.php","h/hello.php");

shuffle($content);

echo file_get_contents($content[0]);

?>
