ReflectionType::isBuiltin

Checks if it is a built-in type

Description

Parameters

This function has no parameters.

Return Values

TRUE if it's a built-in type, otherwise FALSE

Examples

Example #1 ReflectionType::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 something similar to:

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.
