清除来自 PHPMailer 的最后一个异常错误以进行下一个循环

Question

假设我有这个：

$emails = array('some1@email.com', 'some2@email', 'some3@email.com', 'some4@email.com');
foreach ($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());
        }
    }
}

所以在下一个循环中的异常被记住并显示，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，如何在处理错误后清除错误以便重新开始？

Answer 1

由于第二个地址的异常，$mail->clearAddresses() 的行永远不会到达。

因此您的第三封邮件将同时发送到 some2@email 和 some3@email.com，再次抛出异常。

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

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

您也可以在调用 $mail->addAddress($email) 之前调用 $mail->clearAddresses()。这样一来，您将始终确保在添加地址之前清除地址。

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