Sorting :
Contrary to what one might expect, the returned array of ReflectionType objects will not be sorted in the same order than the types declared into the source code.
- Classes, interfaces, traits, iterable (replaced by Traversable), ReflectionIntersectionType objects, parent and self: these types will be returned first, in the order in which they were declared.
- static and all built-in types (iterable replaced by array) will come next. They will always be returned in this order: static, callable, array, string, int, float, bool (or false or true), null.
Notice that when used into an union type, iterable is an alias for Traversable|array. ReflectionUnionType::getTypes will return these both ReflectionNamedType objects, instead of a single one named 'iterable'.
Example :
<?php
class PC {}
class C extends PC {
function f(): null|bool|float|int|parent|PC|string|iterable|(ReflectionClass&ReflectionProperty)|callable|static|self|C {}
}
echo join(', ', array_map(
function($t) { return ($t instanceof ReflectionIntersectionType) ? '<intersection>' : $t->getName(); },
(new ReflectionMethod('C', 'f'))->getReturnType()->getTypes()
)) . "\n";
?>
Will display :
parent, PC, Traversable, <intersection>, self, C, static, callable, array, string, int, float, bool, null

ReflectionUnionType::getTypes
(PHP 8)
ReflectionUnionType::getTypes — Returns the types included in the union type
Descripción
Returns the reflections of types included in the union type.
Parámetros
Esta función no tiene parámetros.
Valores devueltos
An array of ReflectionType objects.
Ejemplos
Ejemplo #1 ReflectionUnionType::getTypes() example
<?php
function someFunction(int|float $number) {}
$reflectionFunc = new ReflectionFunction('someFunction');
$reflectionParam = $reflectionFunc->getParameters()[0];
var_dump($reflectionParam->getType()->getTypes());El resultado del ejemplo sería algo similar a:
array(2) {
[0] =>
class ReflectionNamedType#4(0) {
}
[1] =>
class ReflectionNamedType#5(0) {
}
}

ReflectionUnionType::getTypes can return an array of ReflectionNamedType and/or ReflectionIntersectionType objects only.
