use of define and classes

[Renlok]

Is it possible to define some thing outside of a class and read it inside the class

 

i have something like

define('THIS', 1);

class that
{
function that() {
	echo (!defined('THIS')) ? '' : '';
}
}

 

and it cant see the definition how can i use it like a global variable

Yes it is.

 

define('THIS', 1);

class that
{
    function that() {
        echo "THIS was : " . THIS;
    }
}

$that = new that();

 

Should echo out THIS was 1 once the class is instantiated. If THIS is not defined it would echo out THIS with a notice of an undefined constant.

 

That is the point of a constant, it can be used anywhere within a script as long as it is defined before you try to use it.
