It does. It always has.
It just has started to cause the notice in Apache logs.
Obviously php has changed and the php code has to be changed
accordingly.

Similar things have happened before, php written during a certain version
has probs after php changing to newer version.

There's nothing wrong with doing it manually.

Except I'd need to have that running for multiple directories, one for
the main project, and again for each sub-project.

I could, but the way I work is (usually) to make the required changes
and then do the test builds locally. No point in having it start doing
a build when I'm part way through updating, patching, or adding a
package. Plus, the build script needs to run as root, and in those
circumstances I'd rather do that manually.

You might not want to include it with pages that sets up and uses
database connections. As an alternate to that, take out the parts that
have the sensitive information, put it as a separate script, and then
include it by using require() or require_once(). For extra security,
you could even take that script out of the normally accessible webroot.
As long as it's stored in a location that php can read, and you pass
the path to the file, it will be found and used.

Which PHP version change? PHP4 to PHP5? There were some changes between
them, but I've not noticed anything when upgrading through the various
PHP5 versions.

I've got of them, although each of mine are only about an inch thick.

Strangely enough, that's more or less what's happened to mine. At least
they keep my photography books company.

Now that gives more details that weren't in the first post.

My guess is that before the line:

if ($days > 0) {

you're missing a line:

$uptimeString="";

> Instead of pasting the whole code here it can be seen at

Houghi gave a suggestion on dealing with that.

That works here.

As for my own version, you can find it here:

<http://www.davjam.org/~davjam/uptime.php>

with the page source here:

<http://www.davjam.org/~davjam/uptime.php?code>

Great guess :)
I added that and it seems to have removed the notice.

Does it stay static or does it advance every second?
I'll put the whole thing here, there's javascript in it to make it
dynamic in case the browser supports it.

And if my php skill is zero, javascript is below that...

P.S. There had been a power outage this afternoon here.
Boy, was I surprised to see the uptime page after coming home.
Then the wife told me that the power had been down...
