Hi, I am just learning PHP and have a very simple script to access data in a predefined variable as follows: <body> <?php echo "you are running the file <b>$PHP_SELF</b>.<br /><br />\n"; echo 'you are viewing this page usinig: <br /><b>', $HTTP_USER_AGENT, '</b><br />from the IP address ', $REMOTE_ADDR; ?> </body> However, the assignment does not happen, giving the command line error (PHP Notice: Undefined variable: PHP_SELF in /home/s0460205/public_html/test.php on line 10 you are running the file <b></b>.<br /><br /> you are viewing this page usinig: <br /><b>PHP Notice: Undefined variable: HTTP_USER_AGENT in /home/s0460205/public_html/test.php on line 11 </b><br />from the IP address PHP Notice: Undefined variable: REMOTE_ADDR in /home/s0460205/public_html/test.php on line 11) - why would this occur? Many thanks (I am running PHP/4.3.10)
