将不同条件的if ... elseif链转换为case switch

Question

Simple curiosity, is there any way to convert what this following into a switch loop?

PHP :

if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
    $error = array('type' => 'error', 'value' => 'email');
}
elseif (!preg_match($regex_name, $username)) {
    $error = array('type' => 'error', 'value' => 'username');
}
elseif (!preg_match($regex_name, $firstname) && preg_match($regex_name, $lastname)) {
    $error = array('type' => 'error', 'value' => 'name');
}
elseif ($password !== $password_conf) {
    $error = array('type' => 'error', 'value' => 'password');
}
elseif (checkdate($birthday_d, $birthday_m, $birthday_y) == false) {
    $error = array('type' => 'error', 'value' => 'date');
}
else {
    $error = array('type' => 'success');
}

Thanks.

Just for completeness an example of what a transformation to a switch would look like:

switch(true) {
    case (!filter_var($email, FILTER_VALIDATE_EMAIL)):
          $error = array('type' => 'error', 'value' => 'email');
          break;
    case (!preg_match($regex_name, $username)):
          $error = array('type' => 'error', 'value' => 'username');
          break;
    //...   
}

In the end this is just a complicated way to say if this is true.
