Getting a class's instance?

[Anon]

Ok, I've got a class but I'd like to be able to get the object variable assigned to it - from the class?

An example may help my poor description:

<?
class myclass
{
function myclass()
{
echo "This class is assigned to $className";
}
}

$class1 = new myclass();
$class2 = new myclass();

?>

Ok, the above would print out:

This class is assigned to class1
This class is assigned to class2

Soo, any ideas how I can do that? (atm, I'm passing the name across manually as a parameter in the constructor, but this is messy IMO.

Thanks.

I don't see how the class would know the name of a variable unless you set it after the object has been instantiated.

But out of curiosity, why do you need to know the variable name?

I'm busy implementing an Event Handler to allow some functions within a class to trigger functions within other classes.

When I pass the function to be triggered, I need to pass the object the function belongs to as well.

not sure if this would work. How about creating a function that runs as part of the constructor that parses the source file to find the line and consequently the instance name? seems like a major hack, and not really worth it since you already know the name and can just pass it as a string...

I think you just answered your own question. Pass the object, or a reference to it, as a separate parameter. The "this" keyword will probably give you what you want most of the time.

No that won't work as i'm passing across to separate classes, if I used $this, the event class would try to execute a function within it's class, but I want it to execute a function within the target class ($myClass for example)

Yeah, that does seem even more hacky than my current method of manually passing the variable name. I'll bet it'd be a performance hit too.

But, hey it's another to do it 🙂

Thanks.
