Being a carbo-freak, I just prefer the BREAD acronym to CRUD. I
think I found the BREAD reference first in Wikipedia. (I know, I
know...)

although some people believe differently than i; i would argue
trying to learn how to design w/ the classes that php4 provides
is a waste of time. most books you will find regarding object oriented
design assume the language has the basic constructs. ppp mainly.
also, there are other important facilities php4 lacks like abstract classes
and interfaces, not to mention you have to explicitly assign objects by
reference in php4. (if you dont want a copy created).
unless you are bound to php4 by work or something
i suggest you start working w/ php5. also, if your looking for some design
techniques i recommend studying design patterns. the heads first book
is a great starting point.
actually if you want a solid reference thats free on the web look at
phpPatterns <http://www.phppatterns.com/docs/start>
the code is mostly php4 i believe.

Thanks, Nathan. I have been moving toward the conclusion you suggest
(i.e., don't bother with OOP in php4). Yes, I'm bound to php4
currently.

painfully i find myself bound to it at my current job. there ive been able
to
realize that proper oop can be used to an amazing extent in php4, however
altogether i wish we could just move on to 5 and i could stop writing in
// private
as a comment :)

It sure sounded like you were bitching.
Gee, thanks for pointing that out, Jeeves. I'd say it's pretty damned
obvious now that Rob thought i was bitching about his response to my
query. However, if you'd have bothered to note my replies since, you
might have twigged to the fact that i'd been trying to set that
straight. But you just *had* to send off your own dickish response.
And, your off-list "fuck you, too, asswipe" to me certainly seems to
support that -- don't you think?
How so? Had it crossed your little mind that maybe--just maybe--i was
becoming not a little frustrated with the fact that my reply had been
taken the wrong way? That, instead of accepting that and moving on, this
had become far too OT with bullshit comments such as yours? So, yeah,
you might say that i'm bitching *now*.
You and i have had our run-ins on this list on more than one occasion.
Until now, i've chosen to take your crap in stride. If you have nothing
constructive to add then STFU.
Look, there's nothing you can say to me that hasn't been said before
(some of it deserving), so my advice is for you to refrain from such
conduct and at least try to look professional. That way you'll hide your
ignorance a little longer -- it's always worked for me.
This is me laughing. I'm sure you have no bloody idea how funny that
statement looks from where i'm sitting. See the paragraph above.

It's not so much that i disrespect Rob. It's just that i felt i had to
call him out for being a dickhead by taking my statement out of context.
Tedd ... not so very much at all.

Funny. Reminds of a Capt. Kirk quote:

global variables inside a class ??
as Martin said this is a bad practice.
if you were going to use a global variable inside a class, why bother w/
a class in the first place?
the point is to encapsulate, ie. hide implementation details from the user.
by relying on a global variable, the class is open to behavior modification
by
external code that does not have to go through its well-defined public
interface
to do so. thats why its a bad practice.

Check your apache error logs. My guess is that PHP is making apache
segfault.

No, it's not, but I found out by enabling the show errors in php.ini that
for about 80 items it's saying "PHP Startup: Unable to load dynamic library
'C:\Program Files\PHP\ext\" then the DLL's file name, then "The specified
module was not found" but all the files are there.
