Well I figured it out while I was working on another php script. I can
best describe my problem with an examle.

root/index.php
root/php/date_modified.php

Goal: have the date that index.php was modified added to the page.

index.php 's contents:
<?php
include 'php/hitcounter.php';
?>

date_modified 's contents:
<?php
$filename = 'index.php';
if (file_exists($filename)) {
echo "Page last modified: " . date ("F d Y H:i:s",
filemtime($filename)) . " EST";
}
?>

Now, since date_modified is in a folder ('php') and index.php is in the
root directory, I would have thought that $filename = 'index.php'
should have been $filename ='../index.php', HOWEVER, since the way I am
executing date_modified.php is by including it into index.php, I do not
need to move up yet another directory.

To see this script live you can check out
http://www.cse.msu.edu/~meyerro3 although its nothing fancy, it just
says the date I last modified index.php at the bottom.

Anyways, now I have a new question. Is there another way I can call a
php script to execute other than including it's contents into my
current document? Ideally, I would like to be able to pass over a
variable to date_modified saying which file to check (so I can use it
for more than just my index page.) I like having all my php scripts
organized in a folder set inside root, however, using include() skews
realative pathnames. What if I want to include date_modified into a
page that is located in root/archived_news/whatever.php?

Lastly, and sorry for the essay-sized post, my previous problem with
hitcounter.php has been solved. My problem was that my index page was
..html so none of the php was being executed. Simply renaming it to
..php did the trick, although I have also read that I can play around
with some server-side settings to scan .html files as well.

Cheers,
