Sql查詢返回對象

Question

$sql = "SELECT email FROM users WHERE username='$User'"; 
    $result = $conn->query($sql); 
    if($result->num_rows > 0){ 
     while($row = $result->fetch_assoc()){ 
      $email = $row["email"]; 
     } 
    } 
    echo $email; 
    require_once("class.phpmailer.php");; 
    $email = new PHPMailer(); 
    $email->From = "clientinformation@apbdispatch.com"; 
    $email->Subject = "$from"; 
    $email->AddAddress("$email"); 

回顯$ email時，它返回人員的電子郵件地址。但是，將它放在雙引號中時，我收到一條錯誤消息，指出無法將對象轉換爲字符串。

感謝您的幫助，

點問題：

檢索電子郵件：

 $email = $row["email"]; 

實例化您的郵件：

$email = new PHPMailer(); 
    ^---oops, now your database result is destroyed.
