示例 #1 ReflectionIntersectionType::getTypes() 示例
<?php
function someFunction(Iterator&Countable $value) {}
$reflectionFunc = new ReflectionFunction('someFunction');
$reflectionParam = $reflectionFunc->getParameters()[0];
var_dump($reflectionParam->getType()->getTypes());
?>以上示例的输出类似于：
array(2) {
[0] =>
class ReflectionNamedType#4(0) {
}
[1] =>
class ReflectionNamedType#5(0) {
}
}
