Wish it were, but my test code is bare bones.

cURL -- both PHP and command-line -- fetches files and URLs (remote and local)
w/o issues. file_get_contents() fetches files, but fails on all URLs (remote
and local). This is why I believe the problem lies with the machine's
configuration and not the Firewall.
It's pretty confounding, isn't it? I'm not sure what to do at this point.

But by using something like WireShark you can see exactly what
requests ARE being made. You may be getting a redirect reply which is
failing or something daft. Anything really.

That's the problem, area itself isn't visible, so giving a CSS class won't
highlight it.

I have image map with dynamic circle areas whose coordinates stored in
database. I'd like to colorize these areas so that it's obvious to see them.
Most solutions I found on the net highlights the area on mouse hover, while
my needs is to do it once when the window is loaded. Any idea?
I would say that you should do the following:
1. make a css class, that gives you the highlights you want.
2. put a div with position:absolute over the image where you want the
class to take effect
3. use a javascript to draw the circle in the div. If you look at for
instance the "nifty" and "niftycube" solutiona, they're working with an
inner and an outer color, so the outer should be transparent and the
inner you css class. And my guess is that this has already been made
before, so google for a javascript solution that fits your needs.
Happy hacking.

Allen,
Before you go with my static-approach, please do consider Shawn's registry
pattern suggestion. That's pretty sweet too ;-).
A little response to your long text, before I help you fix the bug. A static
property is basically the same as a regular property on an object. Only
difference is that they are not reset when the class is instantiated into an
object. They are just there.
Now, about your bug. The syntax for referencing a static property is a bit
weird - which has to do with the existence of class constants, which might
have set you off.
Notifier::notifyQueue would reference a class constant. The [] syntax is not
valid here, since a constant is - you got it: constant. And thus cannot be
changed.
Notifier::$notifyQ[] = '<div> ... </div>'; references the static property.
But... since notifyQ is a proptected static property, it is very unlikealy
that you'll ever actually write Notifier::$notifyQ. You add to this queue
from within the class itself, so therefore self::$notifyQ is a lot better.
Does that answer your question?
Btw; Shawn; Assuming that your Registry class holds objects, there is no
need have the ampersand in front of the get method or $object argument.
Objects are *always* references. And you might want to look at the __get,
__set and __isset magic.

I'm actually using a combination of the DSN*-string and the odbc.ini settings.
Thank you!
