PHP Manual: ReflectionNamedType::isBuiltin

Description

public function ReflectionNamedType::isBuiltin(): bool

Examples

Example #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());

The above example will output:

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.
