OO Question

[asa_carter]

I'm starting out with OO and I'm having trouble getting this to work.

Hopefully you can see what I am trying to. I don't want to use
return $class->display(); in content because I am assuming that I dont know the name of the method that I will be calling in there.

$weather = new dialog();
echo $weather->create("Weather");
echo $weather->content(new weather("Campbeltown"));
echo $weather->close();

class dialog
{
public function create($title)
{
	return "<div class='dialog'><div class='dialogTitle'>$title</div>";
}
public function content($class)
{
	return $class;
}
public function close()
{
	return "</div>";
}
}

class weather
{
	private $town;

public function _construct($town)
{
	$this->display($town);
}

function display($town)
{
	return "I live in " . $town;
}
}

It could be useful to just do that. You could create an interface construct (e.g., call it Displayable) that has a display() member function, then have the content() member function take an argument of that interface type. Then to put this together, have the weather class implement that interface construct.

EDIT:
For example:

<?php
interface Displayable
{
    function display();
}

class Dialog
{
    function create($title)
    {
        return "<div class='dialog'><div class='dialogTitle'>$title</div>";
    }

function content(Displayable $item)
{
    return $item->display();
}

function close()
{
    return "</div>";
}
}

class Weather implements Displayable
{
    private $town;

function __construct($town)
{
    $this->town = $town;
}

function display()
{
    return "I live in " . $this->town;
}
}


$weather = new Dialog();
echo $weather->create("Weather");
echo $weather->content(new Weather("Campbeltown"));
echo $weather->close();
?>

By the way, note that the constructor is __construct, not _construct. It is probably better to name the dialog $dialog or $weather_dialog instead of $weather when you have a class named Weather.
