I've had moments like that. (One just yesterday in fact. :-) )
I did subsequently notice with the OP's code you will occasionally get
a negative number, too. Apparently the code enters some sort of
space/time continuum and sometimes manages to go back in time a few
microseconds. (Actually, there is a much more rational explanation for
it if anyone cares, but this one sounds cooler.)

I'm guessing that would be right around the time the PHP interpreter reaches 88
miles per hour and the flux capacitor is activated. :D

You know, I'd use HEREDOC if I could have the closing line indented.
I always think it looks so goofy to have it on the first of a line
inside a method in a class. When things get really weird I tend to
use (s)printf.

*lol* Yeah, I hate how HEREDOC ruins my nice formatting too.

Yeah, me too.
I just slam everything full-left and then I know it's a HEREDOC.

I'm creating a website in php and I've noticed that many websites seem
to "remember where the user is on the page," so that, for example, the
user can click on a link and go to another page, but, when the user
comes back to the original page, it is displayed so that the user is
looking at the same part of the page that s/he was looking at when s/he
clicked the link. This is a mystery to me! How do you create a webpage
so that it "remembers" where the user is on the page and takes her/him
back to that same place on the page when the user returns? There must
be some "trick" to making this happen because a lot of pages do it and a
lot don't (like mine! :-( ). But I'd like to make mine do it too!!
Thanks for any light you can shed for me on this "mystery."

You are probably referring to <a name=""></a> tag placement.
If in your web page you place an anchor tag like this:
<a name="SomeName"></a>
Then in the URL you add this to the end #SomeName it will try and place that
position at the top of your viewable area in your web browser.
http://example.com/myfunpage.html#SomeName
If the page is really long this works just fine most of the time.
Hope this is what you are looking for... :)

Look up the "anchor" part of the URL.

I had a similar problem.
I had a page where the user could edit the page. When the user was in
edit mode, the page was at one spot and when the user turned off
editing, I wanted the user to be back at where he was before editing.
I solved the problem by using javascript and recording the page's
position and then forcing the page to scroll there afterwards.
In any case this all client-side.
Cheers,
tedd

Does this look right?
Obviously you still want to know about production errors, so I'd like
to log them.
Development I want to see -everything- and I want it to display on the
page. The assumption is production won't have any notices as the code
should be clean and our higher priority are fixing errors. But that
one is easily editable if needed :)
Production:
display_errors = Off
display_startup_errors = Off
error_reporting = E_ALL & ~E_NOTICE
expose_php = Off
log_errors = On
error_log = syslog
Dev:
display_errors = On
display_startup_errors = On
error_reporting = E_ALL
expose_php = On
log_errors = On
error_log = syslog
Am I missing any?

Personally, and I know I'm not alone here... I keep E_NOTICE enabled
in production also.

Then you're both mad. Users really shouldn't see any error regardless,
so error reporting IMO should be off entirely. A blank screen that you
can blame on a variety of things is far preferable to users knowing
that your website is broken. In production I keep error_reporting set
to 0. There are a variety of things you could also do like log them to
a file or have them emailed to you so that you get notified when
errors occur.
