$this-> not availabe within the class

[Anon]

Hi,

I have a class with a function and this function has a subfunction. Why can't I access the classes' variables from the subfunction with $this->variable or better: HOW CAN I??

Example:
class testclass {
function mainfunct() {
echo "From mainfunct(): ".$this->myvar."<br>\n";

	function subfunct() {
		echo "From subfunct(): ".$this->myvar."<br>\n";
	}
	subfunct();
}

}

$obj = new testclass;
$obj->myvar = "Hello World";
$obj->mainfunct();

This will output:

From mainfunct(): Hello World
From subfunct():

As you can see the subfunction can't access the variable myvar with $this. Why is that or is there a way to access it (without global $obj and access it that way)?

Thanks,
Matthias

Manuals continue to be your friend:

I read through the manual page you suggest, which is about variable scopes. This is not what I need. Somewhere else in the manual I read that $this-> is used to access all variables within the class, which should in my point of view also work from a subfunction, but it does not.

thanks anyway. are there other ideas?

If you read that manual page properly you'd see that "every" function has it's own scope.
That includes your subfunctions.

So if you dont pass the $this to your subfunction, it doesn't exit in the subfunction.
