As you've said that your excerpt doesn't replicate the problem, it's not
that useful really to accurately illustrate it. I would say for definite
that it's some of the surrounding code, probably something similar to
this:
class Hello
{
private $_world = 'World';
function __construct(){}
function test()
{
$GLOBALS[strtolower(get_class($this))] = $this;
}
}
$clsHello = new Hello();
$clsHello->test();
echo 'The variable $hello is
'.gettype($hello)."\n".print_r($hello,true);
There are probably many ways to achieve this, I can't think of a sane
reason for any of them though!
