我可以告诉ReflectionClass构造函数区分大小写吗？

I have encountered a very interesting problem. I have two classes: APISession and ApiSession. I have an API class as well, which has a method, like this:

public static function request($category, $name, $params) {
    $params["Response"] = new APIResponse();
    $class = new ReflectionClass("API".$category);
    return $class->getMethod($name)->invoke(null, $params);
}

I am calling the method:

$result = API::request("Session", "Check", array());

Naturally, I expect this to execute the Check method of the APISession class, however, I receive the following problem:

Fatal error: Uncaught exception 'PHPErrorException' with message 'Exception 'ReflectionException' with message 'Method Check does not exist'

I have checked the source of the problem and it is caused by the fact that the request is reaching ApiSession instead of APISession, despite the fact that the string passed to it is "APISession". My question is: is it possible to tell the ReflectionClass constructor to be case-sensitive?

Class names are case insensitive in PHP, this can be demontrated by executing this on command line:

php -r 'class APISession { } class ApiSession { }'
