I have looked at several stats gathering code blocks and they use
$HTTP_REFERER. When I use that I get and undefined variable error. I
also tried $HTTP_SERVER_VARS["HTTP_REFERER"] which gets me an undefined
index error. I also tried $HTTP_SERVER_VARS["REFERER"] which generates
the undefined index error.
What should I be using???

Two things:
The undefined notice you are getting is the result of your error_reporting
setting in your php.ini...
http://www.php.net/manual/en/function.error-reporting.php
What is ultimately causing the error is that not all HTTP requests to your
page have a referrer defined, therefore, on the occasions that the client
did not specify the referrer, you are getting the undefined notice because
it did not exist. You can test this my having a page that echoes out the
HTTP_REFERRER variable and also contains a link to itself....I think you
will catch on when you see it in action.
<?php
echo 'Referrer: '.$_SERVER['HTTP_REFERRER'];
echo '<br><a href="'. $PHP_SELF .'">Link</a>';
?>

hi all ~
Got a bit of a problem here, I'm writing a page (well, more like modifying
some code I found ;) ) and the PHP sections appear to be ignored by both
netscape and IE. I'm not sure if it's something with my code, or a lack of
PHP exentions on the apache server that it will be placed on.
I'm copying the whole page worth of HTML into this doc (hope it isn't TO
long.)
Also, for some reason, hotmail doesn't like "< or > or " " tags being copied
from anyplace else, so I get thousands of "&al; or > or "" ... sorry
...
:-/
Any help would be wonderful! Thanks in advance all!
The code (the original, unedited version):
<?php
error_reporting (E_ALL);
/* Allow the script to hang around waiting for connections. */
set_time_limit (0);
$telnetclient = "zeth";
$remotehost[0] = "abandonedrealms.net";
$remoteport[0] = "9000";
$remotehost[1] = "cnn.com";
$remoteport[1] = "80";
$remotehost[2] = "freebsd.org";
$remoteport[2] = "80";
$c = count($remotehost);
$c2 = count($remoteport);
if($c != $c2){
die("You must have both remoteport and remotehost specified for all
servers.");
}
?>

Is it possible to get the actual hostname of a users host such as AOL or
Mindspring by name? I tried the get it by using "gethostbyname" using
the "remoteaddr" of the user but all I get is the IP address, not the
host name.

Sounds like Office has affected your browser and your browser doesn't
recgnise the graphics as a graphic it can open. Either that or the class is
outputting the wrong headers for the image file.
Try:
<HTML><BODY><IMG SRC="jpgraph_lineplot.php"></BODY></HTML>
not sure if this would make any difference though. You could try
reinstalling or upgrading your bowser.

Hi all. I have a problem with my graphics which were running well at some
point but now when I try to run the same scripts, I get a dialogue box for
downloading the specified graph. When I say open, the graph is downloaded in
the form of a 'photo editor'. I'm wondering what could have gone wrong. I
installed office XP and from then I got into the trouble especially whenever
I include the class 'jpgraph_lineplot.php'.
Could anybody help with ideas? Without the line plots, things are working
well.
Opere James.
