the above correctly prints out the remote port and the request method, but chokes on all the other ones (yes, I know half the stuff is commented out). Any ideas on what's wrong?

Why are you using eval? From what I can see, you could just pass the variable:

subsession("Server Software", $HTTP_SERVER_VARS["SERVER_SOFTWARE"]);

That should work.

I've done a whole bunch of coding, and I've usually found that if I have to use eval() then I'm doing something wrong 🙂

Dave, you seem to know a lot about eval, I posted about it a while ago but no-one was able to help (oher than point me to the manual which I'd read and read and read and still can't figure eval out)

The problem is basically a file with countries and their timezone, I'm trying to add the time in that country via statements like...

$sevenhb = mktime (date("H")-7,date("i"),date("s"),date("m"),date("d"),date("Y")); $minusseven = date("H:i:s", $sevenhb); echo $minusseven;

and then put that in a field in the db so that I can simply echo it with the rest of the table in a while loop using eval on it to display it...

But whatever I do, it won't work, its hard to give an exact error because I've had so many, but for the latest...

printf ('<tr><td>%s</td><td align=center>%s</td><td>%s</td></tr>\n',
$myrow["country"], $myrow["timezone"], eval ("$visit"));

where $visit is defined as
$visit = $myrow["time"];

as part of the PHP with in the db gave

\n17:16:10 (correct time at -07:00 GMT)
\n
\n
...

then the table below.
I've tried doing simpler things, like putting in echo "Hello"; and <? echo "Hello"; ?> but nothing seems to work

Any help would be MUCH appreciated!

Thanks
