So what? Those variables do not have to be private or protected in order to function. They dont have to be marked private or protected to function, but in order to prevent client code from latching onto the implementation details of the class; they need to be hidden. many of those variables have nothing to do w/ the functionality the class exposes to client code. if those variables are modified directly, because they cant be protected by ppp, then the functionality of the class can be distorted. that is why ppp exists. PPP exists to place restrictions on stupid programmers. It does not add an functionality, or make the code run faster. Run faster, who said anything about that? Given that ive shown examples from 4 books, some with multiple authors, we can either assume there are a lot of stupid programmers out there or your opinion is the less popular of the 2. what you dont seem to understand is the important of stressing the distinction between specification and implementation. maybe youve had the benefit of working with other developers that arent infact stupid; and they know not to access class member variables directly; but the point is that is a very delicate system. stupid, or more likely uneducated developers will go in and latch onto class implementation details which leads to tight coupling, which makes systems a massive pain to extend and maintain. lets be fair though; youve defined encapsulation as grouping variables and methods, and defined data-hiding as a separate concept, fair enough. my criticism of php4, based upon

I almost always up the memory_limit in the php.ini. Set the memory limit to 16M, or 32M (the default is 8M). You want a higher memory_limit if you're working with big file uploads or creating images with php or anything else that takes a lot of memory. Also, if you're still researching which CMS to use, don't forget to check out Drupal at http://drupal.org. You can learn a lot about PHP by diving into a well written project. The Drupal code is very clean and organized.

No. The idea behind encapsulation is that the implementation, the code behind a method, can change at any time without the outside world being aware of it. Data is *NOT* the implemetation. Tony is right here. Encapsulation is about hiding the details of the implementation and this *can* include information hiding in cases where the purpose of the member variables is likely to change. However, encapsulation does not necessarily imply information hiding. That said information hiding is often achieved using private members and encapsulation. There is a strong relationship between the two, but they are not the same thing. Also, don't forget that abstraction, encapsulation, and information hiding all have a price. Cheers, Rob. -- ...

to the tag in the dom. i have now set it to be a reference to the variable
in the dom.
-nathan:
Not that I provided information otherwise, but
document.getElementById won't work in this case because there are
several links involved. As such, I have to use
document.getElementByClass and that has problems.
Unfortunately, my solution isn't unobtrusive.
a href=img.php?i=?php echo($value);? onclick=window.location =
this.getAttribute( 'href' ) + 's=' + s; return false;
However, I couldn't see a way to make it so.
Why not? I'm guessing because you need to the link to have the
JavaScript variable in it. If this is the case then the href target
should link to a page informing the user that they need to have
JavaScript installed. By doing so you inform them of why clicking on the
link is not having the desired outcome :)
Cheers,
Rob.

-Original Message-
you could easily just print the xml manually.
dvd
titleIDfoo/titleID
baretc/bar
/dvd
or, i believe mysql will return XML output but i'm not sure a PHP
function exists to do that.
no need to use fancy DOM functions, outputting XML is easy, parsing it
is when you need to use the special functions and such.
Here's the 'functions_xml.inc.php' file I use, it has served me well and
handles I believe all tag cases, personally I'm a big fan of using the
attributes as they're most easily parsed out in the PHP DOM functions:

Option 3) setup a dedicated program to handle the mail, such as mailman and then send ONE email from PHP to the listserver which will then dispatch the mail accordingly, properly, in batches. http://www.gnu.org/software/mailman/index.html (at least, that's how I do it currently) -Original Message- From: Martin Zvarík [mailto:[EMAIL PROTECTED] Sent: Saturday, October 06, 2007 11:13 AM To: php-general@lists.php.net Subject: [PHP] Sending lots of emails - 2 choices - choose the best one Hello-- I want to send email to 100+ recipients.

it takes an associative array with a key of NODE for the node name
and makes it a single xml node with all the content in attributes. it
even alphabetizes the attributes. special preparing of the data (like
htmlspecialchars()) might be needed to ensure XML compliance.
i made one to translate it into nodes, but i think at the time i read
that attribute parsing is quicker.
calling it looks like this:
$context['NODE'] = context-info;
$context['current-datetime'] = format_time_xml(time(),UTC);
$context['current-hostname'] = $_SERVER['HTTP_HOST'];
$context['current-page'] = $_SERVER['PHP_SELF'];
$xml = array2xml($context);

What about the reverse - converting the XML back to MySQL?

[PHP] Handling profile view counters
Hi all, I'm contemplating on a proper way of handling a counter for profile views on my auto dealership website. I'm currently confused with the type of algorithm to approach this with. Say a user has a registered session, and views profile a). I can increment the counter for that vehicle. The user can then surf vehicles b,c,dN etc and I'll increment the counter. However, if the same session tries to visit profile a,b,c,d should I not increment the counter? How would you all do it? Any examples with code would be very insightful and appreciated. Thank you kindly. - sf -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Beginner Tutorials for using CLASSES in PHP4
On 10/6/07, Robert Cummings [EMAIL PROTECTED] wrote: Tony is right here. Encapsulation is about hiding the details of the implementation rob, here is tonys definition of encapsulation: Encapsulation is the act of placing data and the operations that perform on that data in the same class. The data does not have to be private at all. tony did not at any point say that encapsulation is about hiding implementation details. im the one who indicated encapsulation is about hiding implementation details. tonys definition is contrary to all the definitions i have pulled from books on object oriented programming (see last post). actually, its not contrary, but it is only part of the definition. encapsulation is infact about hiding implementation details; its about driving client code through a well defined interface, to get access to the behavior the class supplies. in order to implement this behavior there are often times variables *and* methods that client code should not have access to. i pointed out that classes that do not utilize ppp allow client code to become dependent upon their implementation. because weve only been stressing the hiding of member variables (i guess thats what data hiding means) in this conversation i think we have glossed over the fact that it is also important to be able to hide certain member functions as well. this cannot be done in php4, and as i said can lead to systems where client code is made dependent upon the implementation of other classes, which leads to very delicate systems. you guys are not the only php4 advocates ive run into; it just so happens i have a good friend with a very strong php background who tells me practically the same thing, ppp isnt that big of a deal. i disagree, why, is it because ive had a classical education in oop, because ive worked with a number of languages that dont allow you to create class members without specifying an access level? for those reasons and because ive had the misfortune of working in places that have tightly coupled code. im talking about hundreds of thousands of lines of madness. ppp could have saved these systems greatly. Also, don't forget that abstraction, encapsulation, and information hiding all have a price. if youre referring to performance i think the price of not using these tools is also worth mention. namely code which is easily subject to tight coupling, which as i said leads to systems that are difficult to maintain and extend. personally i value maintainability and extensibility over performance, but thats merely a personal preference. (tony) I strongly disagree. It *IS* possible to write perfectly adequate OO programs using PHP 4. If you cannot then you have been taught some bad habits. and what exactly does adequate mean? any oo php4 'program' is inherently weak for the reasons i have sighted, namely the implementation can be latched onto producing tightly coupled code. dont worry tony, i can construe some pretty decent php4 code myself; i wrote a date time package that ive ported to 3 projects including a conversion to php5 in one of those. the point is that the other developers i work with dont have a clue about object oriented concepts which in my experience constitutes the vast majority of php developers. the even bigger point, on the topic of this thread is that php4 is out the door, so there is yet another possibly more important reason not to waste time learning oop studying php4. ive studied oop for years and worked with a number of oop languages; many of the bad habits i had at one point or another have been removed. guess what the first one was, not letting client code access member variables directly :) if you dont mind brittle oop code, php4 will suffice. if you want to tap into real object oriented features, many of which i consider fundamental (such as ppp [to name just one]) go for php5. truthfully i still think there are some features missing; interface hierarchies being the main one, perhaps well get lucky in php6... -nathan
