Question

我正在尝试发送一封包含几个换行符的电子邮件，但每次添加\r\n并且它一直在发出错误时，任何人都知道它为什么会这样做？

错误

警告：输入中出现意外字符：'\'（ASCII = 92）state = 1 in   第24行/home3/hutch/public_html/server1/ForgotPassword.php

警告：输入中出现意外字符：第24行/home3/hutch/public_html/server1/ForgotPassword.php中的'\'（ASCII = 92）状态= 1

PHP

<?php
    if (isset($_GET['Username'])){
        $Username = $_GET['Username'];

        if (is_dir("USERS/".$Username) === true) {

            $myFile=fopen("USERS/".$Username."/Password.txt","r") or exit("Can't open file!");
            $Password = fgets($myFile);
            fclose($myFile);

            require("PHP/class.phpmailer.php");
            require("PHP/class.smtp.php"); 

            $mail = new PHPMailer();

            $mail->IsSMTP();
            $mail->Host     = "smtp.sulmaxmarketing.com";

            $mail->From     = "matt@sulmaxcp.com";
            $mail->FromName = "Online Game";
            $mail->AddAddress("sulmaxcp@gmail.com");

            $mail->Subject  = "Forgot Password";
            $mail->Body     = "You have requested your login details, if this is incorrect please reply to this email letting us know your account has been compromised.".\r\n."Username: ".$Username.\r\n."Password:".$Password;

            if(!$mail->Send()) {
                echo 'Failed to send password to email. Please contact support.';
            }
            else {
                echo 'An email has been sent to your email address associated with the account.';
            }
        }
        else {
            echo 'Username not found!'; 
        }
    }
?>

Answer 1

你需要用＆＃34; \ r \ n＆＃34;等双引号括起\ r \ n。

因为它是您要在邮件内容中添加的字符串的一部分。

我必须强调使用双引号而不是单引号，因为单引号不会解析转义字符\并且只会打印\ r \ n而不是换行符。

Answer 2

如何将系统属性用于新行字符PHP_EOL。使用PHP_EOL常量，该常量自动设置为运行PHP脚本的操作系统的正确换行符。

请注意，此常量从PHP 5.0.2开始声明。

向电子邮件添加换行符时出现警告错误？
