Better way (imho) is to call:
$storage->removeAll($storage);
Especially, that sometimes (had no time to investigate) removeAllExcept(new SplObjectStorage()) leaves some elements.
SplObjectStorage::attach
(PHP 5 >= 5.1.0, PHP 7, PHP 8)
SplObjectStorage::attach — Adds an object in the storage

Beispiel #1 SplObjectStorage::attach() example
<?php
$o1 = new stdClass;
$o2 = new stdClass;
$s = new SplObjectStorage();
$s->attach($o1); // similar to $s[$o1] = NULL;
$s->attach($o2, "hello"); // similar to $s[$o2] = "hello";
var_dump($s[$o1]);
var_dump($s[$o2]);
?>Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:
NULL string(5) "hello"
