Writing Simple Classes in PHP

Hope you have resolved your server problem.

Agree with all the comments prevously posted. You kept it simple enough for just about anybody to understand and used a good example.

You are talking of doing an advanced classes next. How about an intermediary classes one next, with a few more excellent examples, possibly with using more than one class or even using a class within a class.

Many thanks for this article

hehe yeah
i also finally got it

my main problem was with two things

first that class defines a data structure which can be used
multiple types

second the way how $this is handled

i used php 5 and XML subsets
which used a lot of -> as well, and i felt familiar with that

the example you provided now was EXACTLY what i needed to understand it - now i can once again try to tackle the big
c++ code of some of my favorite programs which i need to tweak to make em optimal

well, after all, programming includes repetitive things, so, if you understood something once, you have REALLY learned sth

so
thanks a lot for this

PS: maybe one day you are going into a more complex example using struct and classes for php
to do sth nifty

Indeed a clear example.
But...

What is not clear to me is why you handle the $Content variable different than the other two variables ($Title, $Keywords). The latter ones just get their data by an explicit assignment, whilst for the $content variable the method setContent($Data) is used to pass the data to it.
In other words, in stead of applying:
$Sample->SetContent( $Content );
why don't you use:
$Sample->Content = $Content;

To be honest, there is no reason you can't do that. In fact, that is what I normally do anyway, its quicker. However, I used the functions to demonstrate how to implement functions in classes that required you to pass variables. Most people wouldn't have used a function just for that, you would generally use it for something more complex. I just needed an excuse to demonstrate a function.

Good catch though.

Any help would be appreciated. The if statement is actually below the $NoResultsCode variable, but thought it might be better to show what I am trying to do.

I want to include another php file and place in a variable, say $ShowCalendar. If the if statement is true it does an echo of the "NoResultCode in which I want the variable I have the include stored in. Can this be done?

Thanks

include ("calendar.php");

if ($numberall==0) {
// Here we are saying, if no records found display message and a link to go back to the main index page
echo "$NoResultsCode";

$NoResultsCode = "<a name=\"top\"></a><table border=\"2\" align=\"center\" cellpadding=\"0\" cellspacing=\"0\" bordercolor=\"#000000\">";
$NoResultsCode .= "<tr><td><table border=\"0\" align=\"center\" cellpadding=\"0\" cellspacing=\"0\" bordercolor=\"#000000\">";
$NoResultsCode .= "<tr><td width=\"210\" valign=\"top\" bgcolor=\"#000000\"><p align=\"center\"><img src=\"images/prflogo2.jpg\" width=\"210\" height=\"130\"></p>";
$NoResultsCode .= "<p align=\"center\"></p><p align=\"center\">
</p></td><td width=\"500\" valign=\"top\" bgcolor=\"#FFFFFF\"><div align=\"center\">";
$NoResultsCode .= "


<img src=\"images/admin_deleted_req_title.jpg\">

<span class=\"style1\">Sorry Kevin, no estimate requests
have been marked deleted! </span></p></div></td>";
$NoResultsCode .= "<td width=\"210\" valign=\"top\" bgcolor=\"#000000\"><div align=\"center\"><p align=\"center\"><img src=\"images/construction.gif\" width=\"210\" height=\"130\"></p>";
$NoResultsCode .= "<div align=\"center\">


<img src=\"images/bar.jpg\" width=\"171\" height=\"7\"></p></div>";
$NoResultsCode .= "<p align=\"center\"><span class=\"style8\">Call for a</span> <span class=\"style3\">FREE</span> <span class=\"style8\">Estimate
";
$NoResultsCode .= "515.202.1475
515.288.1161</span></p><p align=\"center\"><img src=\"images/bar.jpg\" width=\"171\" height=\"7\"></p>";
$NoResultsCode .= "<p align=\"center\"><span class=\"style8\">Copyright &copy; 2004 ConcretePRF.

";
$NoResultsCode .= "

$NoResultsCode .= "<p align=\"center\"><img src=\"images/bar.jpg\" width=\"171\" height=\"7\"></p><span class=\"style2\">$ShowCalendar</span>";
$NoResultsCode .= "<p align=\"center\"><img src=\"images/bar.jpg\" width=\"171\" height=\"7\"></p><span class=\"style3\">Current Estimate Schedule:</span></div>";
$NoResultsCode .= "

$NoResultsCode .= "</td></tr></table></td></tr></table></body></html>";

very helpful tutorial! i was having trouble grasping using classes and this explains every element of it.

thanks

Well you did a good job.... The tutorial is really easy to understand and I considered it as a missing link in learning the basic concept of Classes in PHP hehe.... Well that's all folks -Frendel Thanks a lot

[bhutz]

Would just like to say thanks for a really easy to understand tutorial on classes...been lookin through a few all day and would say this has helped my understanding the most.

Thanks again

Very, very good SIMPLE example of what classes actually are. Most of the other tutorials on classes I've tried to read have chosen such a complex subject to begin with, that the concept of 'class' is totally lost in an unpenetrable fog of complexity. So thank you very much to the author of this tutorial.

Now I understand.

I'm just a beginner. Reading through it, I am finally starting to grasp what classes and objects are.

But I was wondering what the output is supposed to look like? I'm not sure if I'm doing it right.
