[SOLVED] What am I doing wrong? (PHP OOP)

[dbx]

I'm trying to teach myself OOP, and it's not going well =)

 

Can someone tell me what is wrong with the following code?:

 

The class I created:

 

<?php

class numbersgame {

var $number;

function setNumber($num) {
	$this->number = $num;
	return;
}

function getNumber() {
	return $this->number;
}
}

?>

 

The page that uses it:

 

<?php

include("the_class.php");

$newgame = new numbersgame();

numbersgame::setNumber("3");

$res = $newgame->getNumber();

echo $res;

?>

 

Now, the way I see it... it should set number to "3" and display it on the page. At the moment, it doesn't display anything.

 

Why? 

 

Thanks.

1. Which version of PHP you use? Don't use PHP4 for OOP.

 

2.

include("the_class.php");

$newgame = new numbersgame();

$newgame->setNumber(3);

$res = $newgame->getNumber();

echo $res;

I am (was) using 4. My server supports PHP5 if I use the .php5 file extension.

 

I've renamed the files and changed that line of code, and it works!

 

Thanks for that.

This code is also PHP4.

<?php

class numbersgame {

   var $number;

   function setNumber($num) {
      $this->number = $num;
      return;
   }

   function getNumber() {
      return $this->number;
   }
}

?>

 

You should change it to PHP5

 

<?php

class numbersgame {

   private $number;

   public function setNumber($num) {
      $this->number = $num;
      return;
   }

   public function getNumber() {
      return $this->number;
   }
}

?>
