ReflectionNamedType::isBuiltin
(PHP 7, PHP 8)
ReflectionNamedType::isBuiltin — Checks if it is a built-in type
Description
public ReflectionNamedType::isBuiltin(): bool
Checks if the type is a built-in type in PHP. A built-in type is any type that is not a class, interface, or trait.
Parameters
This function has no parameters.
Return Values
true if it's a built-in type, otherwise false
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.
