How do I incorporate a function into a class?

Volitics

I'm just now beginning to work with classes. Can anybody tell me how to turn the function (immediately below) into a class? The function outputs a random number.

I'm trying to get the class (all the way at the bottom) to output the random number.

// This function works fine. It outputs a random number.

function CreateRandomNumber () {

srand ((double) microtime() * 1000000);
$RandomNumber = rand(0,5); // Pick an arbitrary starting point.
if ($RandomNumber == 0){
$Number = 1;
	}elseif ($RandomNumber == 1){
$Number = 2;	
	}elseif ($RandomNumber == 2){
$Number = 3;	
	}elseif ($RandomNumber == 3){
$Number = 4;	
	}elseif ($RandomNumber == 4){
$Number = 5;	
	}else{
$Number = 6;		
	}
return $Number;


}

$AdNumber = CreateRandomNumber();


// I'm trying to incorporate the function above into the this class(below).
// When I try to put the function above into the class below it won't work.
// The class below outputs the term "Object" and nothing else.

class RotateAd {

var $Number;

function CreateRandomNumber() {

 	srand ((double) microtime() * 1000000);
 	$RandomNumber = rand(0,5); // Pick an arbitrary starting point.
 	if ($RandomNumber == 0){
	$this->Number = 1;
		}elseif ($RandomNumber == 1){
	$this->Number = 2;	
		}elseif ($RandomNumber == 2){
	$this->Number = 3;	
		}elseif ($RandomNumber == 3){
	$this->Number = 4;	
		}elseif ($RandomNumber == 4){
	$this->Number = 5;	
		}else{
	$this->Number = 6;		
		}
	return $Number;

	}
}

$AdNumber = new RotateAd();
$AdNumber->CreateRandomNumber();

Thanks.

    see this statement...

           return $Number;

you have really missed out something simple...
you should have userd this

return $this->Number;

I tried that after I made the posting last night. It didn't work.

It's something else that's causing it not to work.

I'm just going by an example in a book "Sams Teach Yourself PHP in 24 Hours." The book is a good book but it has limited examples.

Can you think of anything else?

Thanks.

A little optimisation and a fix.

<?php
class RotateAd {

var $Number;

function CreateRandomNumber() {
	srand ((double) microtime() * 1000000);
	$RandomNumber = rand(0,5); // Pick an arbitrary starting point.
	return $this->Number = $RandomNumber +1;
}
}
$AdNumber = new RotateAd;
echo $AdNumber->CreateRandomNumber();
?>

Thanks for the help.

It works. But I've got one other question.

The output, which is a ramdon number, outputs above the<html> tag at the top of the page like this:

1 (or 2, or 3, etc.)
<html>
<body>
</body>
</html>

When I assign the $AdNumber variable down below the tag it outputs like this:

<html>
<body>
Object
</body>
</html>

How can I get the random number output to print down within the Html page?

Thanks.

Nix the above question. I got it figured out.

$AdNumber = new RotateAd;
$FlashAd = $AdNumber->CreateRandomNumber();

All I had to do was put the $AdNumber variable down in the Html page.

Thanks for the help.

$AdNumber = new RotateAd;
$rand = $AdNumber->CreateRandomNumber();

Use $rand as appropriate.
