    Örnek 1 ReflectionNamedType::isBuiltin() example

    <?php
    class 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());

    Yukarıdaki örneğin çıktısı:

    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.
