I'd suggest creating a new .php file, with these contents:

<?php phpinfo(); ?>

and running it on your server. (you may have already done this in a previous lesson, but I'm not sure if Stefan covered that). If you have PHP 4, you won't be able to use "__construct", since that is PHP5 only.

If you are using a program like WAMP or MAMP to run a server on your local machine, chances are, you probably have PHP5. If you are running this on a live server, it is possible that your host hasn't upgraded to PHP5 yet.

If you are using PHP4, you can still use OOP, you just have to use a slightly different constructor. Instead of using "__construct", your constructor method will have the same name as the class (in this case, your constructor will be person()):

<?php         
    class person {
        var $name;

        function person($persons_name) {        <-- constructor
            $this->name = $persons_name;        
        }        
        
        function set_name($new_name) {
              $this->name = $new_name;
        }    
    
        function get_name() {        
              return $this->name;        
         }        

    }         
?>         

If you are running PHP5, and the "__construct" itself isn't a problem, post the code you are working with -- perhaps you have some sort of error that I will be able to catch.
