PHP current file

Hi all,
Could someone please tell me how to reference the current php file. There must be an equivalent to the ‘this’ identifier that’s in flash!

e.g. how could I modify this code so that it’ll run on whichever page its placed.

$last_modified = filemtime(“THIS.php”);
print("<h3>last updated: ");
print(date(“m/j/y h:i</h3>”, $last_modified));

Cheers good people of Kirupa!

ps I’m new to php (big surprise!), what should I call it PHP, php, Php, etc? Just wondered! Thanks again! :slight_smile:
