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.
