Array of Instances Inside Constructor

[phpdevkit]

Can anyone help me figure out how to make a class keep an array of all
of its instances? This was my first and obvious first shot...

class A
{
function A()
{
static $a = array() ;
$this->array =& $a ;

$this->array[] =& $this ;
}
}

But, if I make changes to the instance contents (not included above)
they are lost when I eventually try to use the array of references.

>From what I have read, it is not possible to use a reference to $this

like this because of when memory is actually created by PHP. (It's no
problem if I want to store an array of references AFTER the new
operator has returned the instance but I am trying to make it
transparent and put all of this inside the constructor where it should
be.)

Any tricks or workarounds are appreciated!

Try this:

class Foo
{
public static $arr = [];
public function __construct() {
self::$arr[] = $this;
}
}
