Exemplo #1 ReflectionNamedType::isBuiltin() example

<?php
class SomeClass {}

function 
someFunction(string $paramSomeClass $param2StdClass $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());

O exemplo acima irá imprimir:

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

Note that the ReflectionNamedType::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.

I couldn't find a list of what qualifies as a builtin. Here is what I have so far:
string
float
bool
int
iterable (Iterator reflects as type iterable)
mixed
array

These do not qualify as builtins:
Closure
Stringable
Generator
Traversable
Serializable
Throwable
IteratorAggregate
ArrayAccess
WeakReference
JsonSerializeable

built-in types () are:
- `array`
- `callable`
- `bool`
- `float`
- `int`
- `string`
- `iterable`
- `object`
- `mixed`

Note: tested from the list at https://php.net/language.types.declarations#language.types.declarations.base

`self` & `parent` are not included.
