php - 从PHPMailer清除上一个异常错误以进行下一个循环

Question

可以说我有这个:

$emails = array('some1@email.com', 'some2@email', 'some3@email.com', 'some4@email.com');
foreach ($emails as $email) {
    try {
        $mail->addAddress($email);
        $mail->send();
        $mail->clearAddresses();
    }
    catch (Exception $e) {
        if (strpos($e->errorMessage(), $email) > 0) {
            // so here i can see if i have error like: SMTP Error: The following recipients failed: some2@email
            echo $e->errorMessage();
            echo "<br>";
            echo $email;
        }
        else {
            // so i would see if there is another error, like smtp login failed etc
// here unfortunately on third loop it gives me error from second loop that some2@email is nto valid even when i sent some3@email.com
            die($e->errorMessage());
        }
    }
}

因此会记住并显示下一个循环中的异常，上面的输出是:

SMTP Error: The following recipients failed: some2@email: L6gvk4HSs0vIlL6gvkzbQ0 invalid destination domain <some2@email>
some3@email.com

所以我的问题是，处理错误后如何清除错误，这样我才能重新开始？

Answer 1

由于第二个地址处的异常，因此永远不会到达带有$mail->clearAddresses()的行。
因此，您的第三封邮件将同时发送到some2@email和some3@email.com，再次引发异常。

try {
    $mail->addAddress($email);
    $mail->send(); // try block stops here on exception
    $mail->clearAddresses(); // addresses are not cleared
} catch (Exception $e) {
    // ...
}

您可以在 $mail->clearAddresses()语句之外调用 try, catch。

try {
    $mail->addAddress($email);
    $mail->send();
} catch (Exception $e) {
    // ...
}
$mail->clearAddresses();

您也可以在调用 $mail->clearAddresses()之前先调用 $mail->addAddress($email)。这样，您始终可以确保在添加地址之前已清除地址。

try {
    $mail->clearAddresses();
    $mail->addAddress($email);
    $mail->send();
} catch (Exception $e) {
    // ...
}
