Woops! I was too quick. For associate arrays, instead of building the
complete string manually, you just cast the object to string...
$array[(string) new Obj] = 1;

giorgio dot liscio at email dot it - your last example...
$myarray[new MyClass()] = "foo";
... is solvable by doing this, provided a __toString method is
declared...
// for associative array, you have to manually build the string
$array["'".new MyClass('key1')."'"] = "foo";
$array["'".($obj = new MyOtherClass("test", "something"))."'"] =
$obj->prop2;
// for numbered array, you first have to have __toString cast the
numeric property to (string) before returning
$array[(int) (string) new MyThirdClass(222)] = "foo";
A __toScalar would be really nice. But a problem still is the processor
wouldn't know if you meant for the array key to be a string, an int, a
constant, or what.

arrayaccess interface has a different behavior and allows to pass
instances as keys
anyway there's another issue about "classic" arrays
$myarray[new MyClass()] = "foo";
when used in this context, the instance should call __toString to return
the key as string... or toScalar in the next php releases

Description:
------------
hi
class MyArray
{
public function __set($i,$v){var_dump($i);}
public function __get($i){var_dump($i);}
}
$obj = new MyArray();
$obj->{222} = "foo";
echo $obj->{222};
i think the index of the __set __get magic methods should be as user
passed
with the characteristics of a "php's valid array key"
but in plus...
would be nice if the key accepts all types too
$hashtable->{new User(2222)} = new SomeUserData(2222);
here User is casted to "string" and it is good for hash tables, but
inside the __set method is impossible to access the original "new User"
instance
