Is it possible to have a function with two returns like this:

function test($testvar)
{
  // Do something

  return $var1;
  return $var2;
}

This is the easiest way to do it:

public function selectAllUsersByRole($userRole, $selector) {

    $this->userRole = $userLevel;
    $this->selector = $selector;

    $sql = "SELECT * FROM users WHERE role <= ? AND del_stat = 0";
    $stm = $this->connect()->prepare($sql); // Connect function in Dbh connect to database file
    $stm->execute([$this->userRole]); // This is PHP 7. Use array($this->userRole) for PHP 5

    $usersIdArray = array();
    $usersFNameArray = array();
    $usersLNameArray = array();

    if($stm->rowCount()) {
        while($row = $stm->fetch()) {

            array_push($usersIdArray,    $row['id']);
            array_push($usersFNameArray, $row['f_name']);
            array_push($usersLNameArray, $row['l_name']);

            // You can return only $row['id'] or f_name or ...
            // I used the array because it's most used.
        }
    }
    if($this->selector == 1) {
        return $usersIdArray;
    }elseif($this->selector == 2) {
        return $usersFNameArray;
    }elseif($this->selector == 3) {
        return $usersLNameArray;
    }

}

How can we call this function?

$idData = $selectAllUsers->selectAllUsersByLevel($userRole, 0);
print_r($idData);
$idFName = $selectAllUsers->selectAllUsersByLevel($userRole, 1);
print_r($idFname);

That's it. Very easy.
