Undefined variable notice in class?

[ZachMEdwards]

I'm new to PHP classes. Can someone show me why this is throwing a notice / fatal error? And how do I fix it?

 

test.php:

<?PHP
class testVariable {
	private $test = 'testing';

	public function __construct() {
		echo $this->$test;
	}

}
?>

index.php:

<?PHP
require_once 'test.php';
$test = new testVariable();
?>

 

Notice: Undefined variable: test in C:\www\test.php on line 6

 

Fatal error: Cannot access empty property in C:\www\test.php on line 6

echo $this->test;

 

BTW: It's customary to start class names with Capital letter.

 

class TestVariable {

Thank you, and I'll remember the capitalization custom.

Try with the spacing. Also $this (I thought it was a pre-defined variable) isn't defined but I am not too sure if that's the issue.

 

		echo " .$this->$test. ";

Eagle: $this is a variable containing current object. It needs not to be defined.
