global var - reference to this in constructor

[csn]

class foo {
  function foo() {
    global $bar;

$bar =& $this;
  }
}

function foobar() {
  global $bar;

  ...
}

Should $bar be available to foobar() ? It seems to be undefined. If I don't use a reference in the constructor (i.e. $bar = $this), then $bar is available, but it's a copy.

I think that could be very dangerous.

Think what you are doing!

What happens if you do

$a = new foo;
$b = new foo;

What is $bar -= to ?

Just access the class from the var you create.

$a->foo_function();

In that case there should be three different objects. However with:

$a =& new foo();
$b =& new foo();

They should all refer to a single object.

[HalfaBee]

They can't refer to the same object because you are creating two different ones using new.

Why do you want to do this?
