范例

Example #1 ReflectionType::isBuiltin() example

<?phpclass SomeClass {}function someFunction(string $param, SomeClass $param2, StdClass $param3) {}$reflectionFunc = new ReflectionFunction('someFunction');$reflectionParams = $reflectionFunc->getParameters();var_dump($reflectionParams[0]->getType()->isBuiltin());var_dump($reflectionParams[1]->getType()->isBuiltin());var_dump($reflectionParams[2]->getType()->isBuiltin());

以上例程的输出类似于：

bool(true)
bool(false)
bool(false)

Note that the ReflectionType::isBuiltin() method does not distinguish between internal and custom classes. To make this distinction, the ReflectionClass::isInternal() method should be used on the returned class name.
