The stdClass classstdClass
&reftitle.intro;
A generic empty class with dynamic properties.
Objects of this class can be instantiated with
new operator or created by
typecasting to object.
Several PHP functions also create instances of this class, e.g.
json_decode, mysqli_fetch_object
or PDOStatement::fetchObject.
Despite not implementing
__get()/__set()
magic methods, this class allows dynamic properties and does not require the
#[\AllowDynamicProperties] attribute.
This is not a base class as PHP does not have a concept of a universal base
class. However, it is possible to create a custom class that extends from
stdClass and as a result inherits the functionality
of dynamic properties.
&reftitle.classsynopsis;
#[\AllowDynamicProperties]stdClass
