Question

I have a template class which goes like this:

class Template{
public $pageTitle = "";
public function __construct($pageTitle){
    $this->pageTitle = $pageTitle;
}

public function display(){
    include "/includes/head.php";
    include "/includes/body.php";
}
}

Now, I’m used to Java’s workings but I don’t understand why I’m getting an undefined variable ($pageTitle) error. The included files need to be able to access that variable. I know it’s going to be very simple but I actually haven’t found out why.
What do I need to do to allow includes to see this variable?

Answer 1

The includes will also have to use $this->pageTitle. Effectively, the include makes them part of the method body.
