&Description;
8.3.0
Calling this method with a single argument is deprecated,
instead use ReflectionProperty::setValue(null, $value)
for static properties.
8.1.0
Private and protected properties can be accessed by
ReflectionProperty::setValue right away.
Previously, they needed to be made accessible by calling
ReflectionProperty::setAccessible; otherwise
a ReflectionException was thrown.
