Is this function secure or could it be more secure, if so how

Question

just a quick question,

Is this function secure, if not how can I make it more secure?

  public function Reg($name, $email, $password)
{
    try {
        
        $db=DB();
        $state = $db->prepare("INSERT INTO reg (name, email, password) VALUES (:name, :email, :password)");
        $state->bindParam("name", $name);
        $state->bindParam("email", $email);
        $encpass= hash('sha256', $password);
        $state->bindParam("password", $encpass, PDO::PARAM_STR);
        $state->execute();
      return $db->lastInsertId();
    } catch (PDOException $e){
        exit($e->getMessage());
    }    
}

As always thanks for any help in advance and its much appreciated for any help you can give

So is this correct

    public function Reg($name, $email, $password)
{
    try {
        
        $db=DB();
        $state = $db->prepare("INSERT INTO reg (name, email, password) VALUES (:name, :email, :password)");
        $state->bindParam("name", $name);
        $state->bindParam("email", $email);
        $hashed_password = password_hash($password, PASSWORD_DEFAULT);
        $state->bindParam("password", $hashed_password, PDO::PARAM_STR);
        $state->execute();
      return $db->lastInsertId();
    } catch (PDOException $e){
        exit($e->getMessage());
    }    
}
