PHP Regular Expression for formatting comments...

I'm trying to clean up some comments in a bunch of pages, and I want them to be in this format:

/* this is
 * a comment
 * and I like it with a space in front of the asteriks
 *
 */

But most of them seem to be like this:

/* this is a comment
foo bar
comment text
*/

Can I use regex to fix them? And if so what would it be?

Try this out:
<?php
         $source = <<<HERE
/* this is a comment
foo bar
comment text
*/
HERE;

         echo "<pre>";

         while (preg_match('#(/\*(?:[^*]|\*(?!/))*^)\s*(?![\s*])#m', $source, $match)) {
             $source = str_replace($match[0], $match[1] . " * ", $source);
         }

         echo $source;

         echo "</pre>";			
?>

kaufmed is probably right (usually is) but I am curious -- how many such files are involved?
