为下一个循环清除PHPMailer中的最后一个异常错误

Question

假设我有这个：

$emails = array('[e-mail]', 'some2@email', '[e-mail]', '[e-mail]');
foreach ($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 $email;
}
else {
// so i would see if there is another error, like smtp login failed etc
// here unfortunately on third loop it gives me error from second loop that some2@email is nto valid even when i sent [e-mail]
die($e->errorMessage());
}
}
}

因此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>
[e-mail]

所以我的问题是，我如何在处理错误后清除它，以便重新开始？

Answer 1

由于第二个地址出现异常，因此永远无法到达具有$mail->clearAddresses()的行。

因此，您的第三封邮件将同时发送到some2@email和[e-mail]，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();

您也可以在呼叫$mail->addAddress($email)之前先呼叫$mail->clearAddresses()。这样，在添加地址之前，您将始终确保地址已清除。

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