list of included file names

Hi, I searched the archives for this. For debugging purposes, I want to see a list of the included files on a page in HTML comments. PHP_SELF and HTTP_SERVER_VARS["SCRIPT FILENAME"] only returns the name + path of the file calling the included files. I want each included file to contribute its name to the page. Is there any way to do that so that the source looks like this: <!-- These files contribute to this page - -> <!-- species_inc.php - -> <!-- db_connect_inc.php - -> <!-- constants_inc.php - - > Thanks Tim
