php - 为什么通过 php 发送的电子邮件中的文本被换行？

Question

我正在为我网站的客户编写一个用于确认订单的电子邮件脚本。我遇到了一个问题，即电子邮件中显示的订单总数被放置在一个新行中，但是代码中没有新行。我附上了正在发生的事情的图像。

这是我的代码:

<?php
  if(isset($_POST['email']) && isset($_POST['name']) && isset($_POST['order'])) {
    $to = $_POST['email'];
    $name = $_POST['name'] .",";
    $order = $_POST['order'];
    $trackingNumber = $_POST['trackingNumber'];
    $totalAmount = "Your total was: $".$_POST['totalAmount'];

    if(!empty($to) && !empty($name) && !empty($order)) {

      $subject = 'From the band.it team ';
      $text = "My name is Bobby and I am a part of band.it's fulfillment Team! We recieved your order and are working to process it from our Gainesville, Florida facility. Feel free to reach out to us at any point with any comments, questions, or concerns. You can find our contact infomation at the bottom of this email.";
        $body = "Hey ".$name."\r\n".$text."\r\nYour order will contain:\r\n".$order."\r\n";
      $body = $body.$totalAmount;
      $body = $body."\r\nYou can track your package through USPS with this number:\r\n".$trackingNumber."\r\n";
      $body = $body."\r\nYou can view any order you've made with us via going to the following link with your tracking number handy!\r\nhttps://camerabandit.com/findAnOrder/";
      $body = $body."\r\n\r\nThanks again for your support of the band.it team, and reach out to us anytime by sending an email to contact@camerabandit.com";
      $headers = 'Order Confirmed';

      if (mail($to, $subject, $body, $headers)) {
        echo 'Mail has been sent';
      } else {
        echo 'Mail failed to send';
      }
    }
  }
?>

我最好的猜测是 $_POST['totalAmount'] 包含换行符。
您可能想要 trim()它:

$totalAmount = "Your total was: $".trim($_POST['totalAmount']);
