Back To Class

yet another good article, bravo sizlere!

Yea, I read the article, and it really seems to pull object oriented programming down from the ivory tower to something us mere mortals can use. Seems very clear. Can't wait to try it. Keep up the good work! Thanks.

Well, I'm a web developer that uses classes extensevely at work, and I was reading the article when I found a big mistake:

Class whatever
{

function foo()
{
}

}

There are parenthesis on the functions for the classes, instead of braces.

Now, usually this would not be a big deal, but since this article is aimed at newcomers on PHP and OOP in PHP, this can be a problem for newbies.

Huh?

class whatever
{

function foo()
{
// function code
}

}// end class

Is correct. It HAS to have BOTH parenthesis and braces not braces INSTEAD of parenthesis.

This is a nice article on the use of PHP or general Object oriented classes. It would help a novice to an expert programmer to create reusable robust code.

Hi, just wanted to let you know i-ve been reading articles from devshed since 1998, and i think it-s the best tutorial site i-ve ever found.

This article is just perfect for non-guru guys (like me) trying to understand OOP and classes.

Thanx.

Well, the example of a <b>table class</b> is pretty good. But it has nothing to do with real table task, or not finished (seems to me as newbe): how would I supply the real data into the table - as <b>flexible</b> as the table class itself?

The code on the board is correct the syntax for functions within a class in the article are wrong.

The explanation of a situation where class is preferred (several objects) is not convincing.

Let's assume, I have several shopping carts.
<br>
Every cart with its own functions? Where functions are <b>the same</b>?
<br>
It can be made as well with an array of cart variables and one set of functions for all carts.
<br>
<p>
<br>
The modularity of code is also not a reason: the above mentioned array and functions can be included as separate file as well.
<br>
<p>There is something more important with classes, what is unfortunately not mentioned here.

Ah, you are right. I was going by what jpm wrote and didn't look at the article.

more than reusing in the net???? its great that ideas could be seen and more style could be heard......
code well i guess classes are good /code

Devshed sure has picken up the pace lately, great job guys! You make us happy.

IN the extension example, the draw table function uses cell spacing which is not defined in the original class but in the extended class only. The drawTable() function should be part of extended class not the original one. The drawTable() in the original should not use cell_spacing.

Hello!

You're absolutely correct - the function code should be included within curly braces, not regular parentheses.

I don't know how I missed that error when writing the article. Thank you for pointing the oversight out, and apologies to everyone who was affected by it.

A corrected version will be posted shortly.

Please do *NOT* use the .php4 extension. It's bad practice, and a support nightmare. it should be .php, plain and simple. (there is a reason it comes that way in your httpd.conf!)
