I am using PHP 7.3.4-1+ubuntu18.04.1+deb.sury.org+3.
Tried the code snippet in the document for WeakReference.
$obj=new StdClass();
$weakref =WeakReference::create($obj);
var_dump($weakref->get()); //
unset($obj);
var_dump($weakref->get());
OUTPUT
=======
PHP Fatal error: Uncaught Error: Class 'WeakReference' not found in Command line code:1
