Pretty nice. Also you can simply run this code <? phpinfo(); ?> and get the output regarding the total no. of available envoirnment variables which are available for you to use. Use those values inside $_SERVER['VARIABLE-NAME-HERE'] and impress your clients

I like $_SERVER['HTTP_REFERER'] (that's not a typo--there's supposed to be only one R after the second E). Sometimes it's interesting to see, and you could also make a database of the referrers and see what site gives you the most hits.

Dont use print, use echo. Its' faster. Only use print when you are using the "or" operator. Liek dis <?php fopen($file, 'w+') or print('Could not open file'); ?>
