Php Mail() 函数：打印了标题

Question

我试图在 PHP 中使用 mail() 函数发送邮件。电子邮件发送成功，并且它存在于收件箱中。问题是打印在电子邮件标题中的标题。我已经尝试了标题的各种代码。 1.第一个是这样的：

$headers = "From: My Example Email".'\r\n'.
"MIME-Version: 1.0".'\r\n'.
"Content-Type: text/html; charset=ISO-8859-1".'\r\n'.
'X-Mailer: PHP/' . phpversion();

结果：My Example EmailrnMIME-Version

2.第二个标题代码：

$headers = "From: My Example Email"."\r\n".
"MIME-Version: 1.0"."r\n".
"Content-Type: text/html; charset=ISO-8859-1"."\r\n".
'X-Mailer: PHP/' . phpversion();

结果：电子邮件未发送

3.第三个标题代码：

$headers = "From: My Example Email".'"\r\n"'.
"MIME-Version: 1.0".'"\r\n"'.
"Content-Type: text/html; charset=ISO-8859-1".'"\r\n"'.
'X-Mailer: PHP/' . phpversion();

结果：My Example Emailrn

我使用 PHP 5.4.19。任何答案都会有帮助。

更新

这是我的全部代码：

class User{
 function callname(){
     $user = $_SESSION['id'];
     $query = ("SELECT * FROM user WHERE user.id='$user'");
     while ($result=mysql_fetch_array($query)){
          echo ($result['username']);}}}

$user = new User;

if($_SERVER["REQUEST_METHOD"] == "POST"){
   $username = mysql_real_escape_string(trim($_POST['username']));
   $check = mysql_num_rows(mysql_query("SELECT * FROM user WHERE username='$username'"));
 if ($check==TRUE){
   $name = $user->callname();
   $to = "myemail@domain.com";
   $subject = "Example Subject";
   $headers = "From: My Example Email".'"\r\n"'.
   "MIME-Version: 1.0".'"\r\n"'.
   "Content-Type: text/html; charset=ISO-8859-1".'"\r\n"'.
   'X-Mailer: PHP/' . phpversion();
   $message = "Hai $name, this is the new message.";

        mail($to, $subject, $message, $headers);
} else {
?>
    <script type="text/javascript">
        alert("Sorry, username not exist !");
    </script>
    <?php }}

新的更新：

经过长时间的尝试和这里的大家的帮助，终于找到了解决方案。但也许这很不寻常。

$headers = 'From: My Example Email'.'""'.
'MIME-Version: 1.0'.'""'.
'Content-Type: text/html; charset=ISO-8859-1'.'""'.
'X-Mailer: PHP/' . phpversion();

但我还不明白。一些文献说每个部分都应该用“\r\n”粘合，但这在我的代码中不起作用。 感谢您的每一个帮助。非常感谢。这真的很有帮助。

Answer 1

你可以试试我的php邮件功能。此功能将为您的电子邮件生成 RFC 兼容的正文和标题部分。

function buildMime($msg){
$num = md5(time());
$num = "_001_".$num."_";

$headers = "From: SenderName<senderEmail@adress.com>\n";
$headers .= "Return-Path: <senderEmail@adress.com>\n";
$headers .= "Reply-To: <senderEmail@adress.com>\n";
$headers .= "MIME-Version: 1.0\n";
$headers .= "Content-Type: multipart/alternative;\n";
$headers .= "   boundary=\"".$num."\"\n";
$headers .= "X-Mailer: PHP v".phpversion()."\n";

$body = "This is a multi-part message in MIME format.\n\n";

$body1 = "--".$num."\n";
$body1 .= "Content-Type: text/plain; charset=utf-8\n";
$body1 .= "Content-Transfer-Encoding: 8bit\n\n";

$body1 .= trim(strip_tags($msg))."\n";
$body1 .= "\n";

$body1 .= "--".$num."\n";
$body1 .= "Content-Type: text/html; charset=utf-8\n";
$body1 .= "Content-Transfer-Encoding: 8bit\n\n";

$body1 .= $msg;
$body1 .= "\n";



$bodyx = "--".$num."--\n";
return array('body' => $body.$body1.$bodyx, 'headers' => $headers);
}
$mime = buildMime("<h1>Hello</h1><p>this is my firs test message</p>");
mail('whereToSend@email.com', 'Your subject', $mime[body], $mime[headers]);
?>

Answer 2

$headers = "From: My Example Email"."\r\n".
"MIME-Version: 1.0"."\r\n".
"Content-Type: text/html; charset=ISO-8859-1"."\r\n".
'X-Mailer: PHP/' . phpversion();

试试这个

Answer 3

$headers = "MIME 版本：1.0" 。 "\r\n";
$headers .= "内容类型:text/html;charset=UTF-8" 。 "\r\n";

$headers .= '来自：' 。 "\r\n";
$headers .= '抄送：myboss@example.com' 。 "\r\n";

邮件($to,$subject,$message,$headers);

Answer 4

您没有正确封装引号。

正确的做法...

$headers = 'From: My Example Email'."\r\n".
    'MIME-Version: 1.0'."\r\n".
    'Content-Type: text/html; charset=ISO-8859-1'."\r\n".
    'X-Mailer: PHP/' . phpversion();

EDITED CODE

<?php
class User{
    function callname(){
        $user = $_SESSION['id'];
        $query = ("SELECT * FROM user WHERE user.id='$user'");
        while ($result=mysql_fetch_array($query)){
            return $result['username'];}}}

$user = new User;

if($_SERVER["REQUEST_METHOD"] == "POST"){
    $username = mysql_real_escape_string(trim($_POST['username']));
    $check = mysql_num_rows(mysql_query("SELECT * FROM user WHERE username='$username'"));
    if ($check==TRUE){
        $name = $user->callname();
        $to = "myemail@domain.com";
        $subject = "Example Subject";
        $headers = "From: My Example Email"."\r\n".
            "MIME-Version: 1.0"."\r\n".
            "Content-Type: text/html; charset=ISO-8859-1"."\r\n".
            "X-Mailer: PHP/" . phpversion();
        $message = "Hai $name, this is the new message.";

        mail($to, $subject, $message, $headers);
    } else {
        ?>
        <script type="text/javascript">
            alert("Sorry, username not exist !");
