For those who stumble on notice about ReflectionType::__toString() beeing deprecated, use method ReflectionNamedType::getName() instead which is not yet documented.
(PHP 7, PHP 8)
ReflectionType 类报告有关函数的参数/返回类型以及类的属性类型的信息。Reflection 扩展声明了以下子类型：
| 版本 | 说明 |
|---|---|
| 8.0.0 | ReflectionType 已成为抽象类，ReflectionType::isBuiltin() 已移至 ReflectionNamedType::isBuiltin()。 |
For those who stumble on notice about ReflectionType::__toString() beeing deprecated, use method ReflectionNamedType::getName() instead which is not yet documented.Method ReflectionType::getName() does not exist. This may have been virtually true in the past but not anymore. It exists on ReflectionNamedType which used to be the only child class of ReflectionType. So you could have kind of relied on that.
But in PHP 8 there's also ReflectionUnionType which doesn't have the getName() method. So in order to support PHP 8, you need to support both ReflectionNamedType and ReflectionUnionType.
