How to get all the content from a directory using PHP

I've been developing a small CMS. It solves a small problem. Some of our customers would like to edit small amounts of text on a page. I don't want to create a CMS database for this. I just want to use text files. There is a tiny CMS which does this, but your website has to be in root, there is an install and it's a bit of a pig to configure.
My CMS is much simpler than that.
Anyway, to cut a long story short I created a PHP function for it which I wanted to share. It takes a directory name as a parameter then looks at that directory  and reads all the files within it. Obviously missing out those ugly  . and .. at the beginning. Manipulate at will.


<?php
function getDirContents($dirLoc)
{  
    foreach(array_slice(scandir($dirLoc),2) as $fileEntry)
    {
        echo file_get_contents($dirLoc.'/'.$fileEntry);
    }
}
?>
