Question

我的代码有效，但由于某些奇怪的原因，当我返回一个字符串时，它会增加额外的空间，我认为也是一个新行。下面的代码工作正常。但是，使用Ajax获取的长度为11时，字符串成功的长度为7，因此这不正确，并且在比较时也不等于“成功”。我已经查看了其他一些问题，但他们提供的所有解决方案似乎都不适合我。据我所知，在任何地方都没有尾随空格。而且它也不是来自我要求的任何文件。

    $mailchimp = htmlspecialchars($request['mailchimp']);
    $dataArray = json_decode($data, true);
  ob_start();
  include('mail.php');
  $mailHTML = ob_get_clean();
  $success = 'success'; 
  if (!empty($mailchimp)) {
// add email to mailchimp list 
    $client = new MailChimp('-us14');// get from setttings
    $list_id = ' ';// get from setttings 
    $result = $client->post("lists/$list_id/members", [
            'email_address' => $email,
            'status' => 'subscribed',
          ]);
  }
    $to = " @icloud.com";// get from setttings 
    $subject = "Offerte van " . $name;// // get from setttings  (maybe...)
    $message = $mailHTML; 
    if(wp_mail( $to, $subject, $message)){
    return $success;
  } else {
    // return 'error'; 
  }
}
?>

PHP使用return语句返回额外的空格？
