Of course its working, this is not about a bug but about sleekness and
PHP-to-programmer support ;-)
These assignment-lists are really lengthy and contain too many repetitions.
Its more like requesting the ternary operator instead of the "old" if ... then
... else ...

So object literals. Getting to use names instead of strings.
Meanwhile
$object = new Object();
$object->StringMember = "content";
// etc
doesn't work?

I view as a strength of PHP, not having to declare all fields in a class. For
example think of a class representing a HTML DOM element, like a link. It allow
many fields, but most often you will only use some of them, like "href" or
"class".
In my opinion the best syntax to write is something like:
$link = new Link(href: "target.html", class:"btn btn-info");
At the moment I use arrays:
$link = (new Link)->assign("href" => "target.html", "class" => "btn btn-info");
But the fields in the strings are messy and un-recognizeable.
Phpdoc is far too cluttering. Declaring every possible option is pointless for
some classes, especially if they are highly dynamic, like derived from a
database table.

Keeping in mind that your IDE could not possibly give you support for arbitrary
properties on objects, they probably do support the @property phpdoc. Add that
to __get/__set and you have
/**
* @property string $StringMember
* @property int $Counter
* @property mixed[] $ArrayMember
*/
class Foo {
private $data;
public function __construct(array $data) { $this->data = $data; }
public function __get($name) { return $this->data[$name]; }
public function __set($name, $value) { $this->data[$name] = $value; }
}
$foo = new Foo([
"StringMember" => "content",
"Counter" => 42,
"ArrayMember" => ["old" => "way"]
]);
$foo-> // should autocomplete/suggest StringMember, Counter, and ArrayMember
If you're talking about the {} syntax you used,

Description:
------------
As PHP does not support *real* overloading by different parameter sets, arrays
are being used for dynamic parameters as well as for object initialization in
constructors.
However arrays use strings as keys, which kills syntax highlighting and
refactoring capabilities in IDEs.
PHP engine should provide a way to initialize an object inline by dynamically
providing parameters to new().
Test script:
---------------
$object = new Object({
StringMember: "content",
Counter: 42,
ArrayMember: ["old" => "way"]
});
Expected result:
----------------
$object->StringMember = "content";
$object->Counter = 42;
$object->ArrayMember = array("old" => "way");
$object->MoreProperties = "stay untouched";
Actual result:
--------------
not possible.
