我有一个简单的代码，可以通过循环发送电子邮件。它在数组中发送一堆电子邮件，然后在没有异常或错误的情况下停止。这是我使用的代码。

$array_emails = [
  [
    "email" => "[email protected]",
    "body" => "message"
  ],
  ...
];

$emailService = new EmailService();
$emailService->sender($senderEmail, $senderName);
$emailService->subject($subject);
foreach ($array_emails as $item){
  try{
    $userEmail = trim($item["email"]);
    $logger->log_debug("Sending email to '$userEmail'");
    $result = $emailService->send($userEmail, "", $item["body"], $logger);

    if ($result) {
      $logger->log_info(">>> Email is sent to '$userEmail'");
    } else {
      $logger->log_error("!!! The email is not sent to '$userEmail' due to: $emailError");
    }
  } catch (Exception $ex) {
    $logger->log_debug($ex->getMessage());
  }
}
$emailService->close();

有什么想法吗？我不是 PHP 专家，可能我错过了谜题的节奏。非常感谢您的帮助。

我每天使用此代码发送一次电子邮件。循环毫无规律地停止，有时它会完成其工作，有时只会发送几封电子邮件。

如果你看一下我发布的代码，会注意到我使用了 $logger 和 try/catch 块。 $logger 配置好了并且工作正常我添加了这些项来捕获异常/错误。所以我发布了我使用的实际代码。问题是循环在函数之后停止在数组的中间 send 。
