Variables in Classes

[kartano]

I have a question about using variables in classes.

With the following code:

<?
class myTest
{
var $first;
var $second;
var $third;

function myTest()
{
	$this->$first="First";
	$this->$second="Second";
	$this->$third="Third";
}

function out()
{
	print($this->$first);
	print($this->$second);
	print($this->$third);
}

}

$justatest = new myTest();
$justatest->out;
?>

The output that I get is:

ThirdThirdThird

What am I doing wrong with the variables here??

Try this

<? 
class myTest 
{ 
var $first; 
var $second; 
var $third; 

function myTest() 
{ 
$this->$first="First"; 
$this->$second="Second"; 
$this->$third="Third"; 
} 

function out() 
{ 
print($this->first); 
print($this->second); 
print($this->third); 
} 
} 

$justatest = new myTest(); 
$justatest->out; 
?> 

I also think you should be using a return than echoing/printing anything out.. Especially in a class...

Mate, for sure!

I used the above class because I'd noticed something odd with class variables in a project I'm working on. The above seems to happen with any varibles I have in any class I design.

<?php  

class myTest  

{  

var $first;  

var $second;  

var $third;  

function myTest()  

{  

$this->first="First";  

$this->second="Second";  

$this->third="Third";  

}  

function out()  

{  

print($this->first);  

print($this->second);  

print($this->third);  

}  

}  

$justatest = new myTest();  

$justatest->out();  

?>  

This works i tested it

Yep, 100%! Thanks for that!

You had this

$justatest->out;

Which shoulda been this $justatest->out();

You should have gotten an error. Thats probably why i didnt really look for it.
