What is stdClass in PHP, and is it the base class for all objects?

Delving into stdClass: What It Is and What It's Not

stdClass, a PHP class often referred to as "generic" or "empty," plays a significant role in object casting. Contrary to popular belief, it is not the foundation for PHP objects.

This misconception can be easily debunked:

class Foo {}
$foo = new Foo();
echo ($foo instanceof stdClass) ? 'Y' : 'N'; // outputs 'N'

While stdClass comes into play when casting other types to objects, it does not serve as the base class for objects in PHP. The language lacks a concept of a central object from which all other objects inherit. Understanding this distinction is crucial for an accurate comprehension of stdClass's role in PHP.
