The practical use of an abstract class is in its ability to define
criteria for classes that inherit from it. How practical would it be to
define a 'truck' class with 4 wheels and then define a 'car' class with
4 wheels when we could define an abstract class that defines vehicles
with 4 wheels? Both of our classes can now inherit from that abstract
class and we can define features only relevant to them. If you refactor
diligently you will no doubt find places where you need to create
abstract classes.
The methods that are exposed by an object define the interface for that
object. It is how everything outside of the object interacts with the
object. You don't have to know how the method works all you need is the
interface....like the gas pedal on the car.

Just adding one line to the topic...
Interfaces are like C or C++ headers files. Them are used to another
class(program in C) to call methods without care the implementation. In
other hand abstract classes are (as the name says) an abstract way to use
multiple specializations of the same group of classes. Like vehicle is an
abstraction to car, motorbike, bike... with that you can use the method ride
to all these vehicles using an vehicle variable pointing to an instance of
car, motorbike or bike.
Cheers.
Rodrigo Reis.

Greetings,
Can any of you point me in the right direction on how to use PHP to create a
most viewed or most clicked articles list? Can it be done with PHP?
Thank you so much,

are these articles on a site youre creating? it should be pretty simple
then. basically, when somebody clicks on a link to an article on the site,
drive that request through some php code that increments a counter in the
database. then on the page where you show the 'most clicked' its
essentially just an ORDER BY most_clicked DESC LIMIT x query. where
most_clicked is the field name of the counter, and x is the number of
results you want to show; so like for top 3, x=3.

Short answer, yes.
The right direction would be something like this:
In the article table of your db add a 'reads' field or similar. Modify
your article display code so that when it loads it increments the reads
field for that article.
Now to display the article with the most reads you just query the
article table for the max reads or for all articles and sort on reads,
etc...

Hi,
I would like to ensure that our php.ini is fully locked down to prevents
individuals from any exploiting vulnerabilities in our site.
(hershonline.com) What sites do you recommend to gather this information?
Do you recommend running tools like securitymetrics.com? I ran this on our
site (hersh) and found no real errors. However, I want to make sure that
hersh site is fully secure.
Thanks for the advice.
Thanks,

Yes, by all means, you will want to protect PHP from your
corporation. In fact, we all want you to do the same.
No posts in four years, and then - bam! - six posts in one day on
three different lists saying the same thing. A little antsy, are we?

Hi gang:
Check out my new game:
http://webbytedd.com/quarters/
What do you think?
that's cool, the only problem is that I lost ten times out of ten ;)
maybe on the weekend I give it a deeper analysis and so I can figure out
the winning strategy - because there must be one, which is used by the
program
greets,
Zoltán Németh
Cheers,
tedd
PS: I originally wrote the game for the Mac over eight years ago.

Probably been answered a thousand times; if so, just tell me where to
look.
I have a function that includes a specific sql query that is used on
only one page on the site. Should that function be coded (1) in the page
itself, (2) in a separate file that only that page includes, or (3) in a
master file that contains all the functions used on the site and is
included on every page?
I've been doing #1 (not actually a function in this case) but #3 is
appealing, especially since I would implement it as OOP and the page
itself would be really just a template. What is the cost of parsing a
bunch of functions that are not used on a given page load?
Q: where to put a function?
A: into the class where it belongs.
sorry I could not stand it ;)
to be more serious, one giant 'functions.php' include file is not a very
good solution, because you might end up including dozens of unused
functions in every page.
on the other hand, putting it into the page doesn't let you use it
anywhere else.
so the solution should be somewhat like the oop class organization: put
together those that are logically belonging together. this way you'll
have libraries for each type of functions, and only include what you need
