请帮助我，我在使用 php 发送 html 格式的邮件时遇到问题，mail() 我认为问题出在标题上。我包含了两个仅在单引号或双引号中略有不同的标题：

标题 1：

$headers = 'From: webmaster@example.com\r\n Reply-To: webmaster@example.com';
$headers .= '\r\nContent-Type: multipart/alternative; boundary="'.$random_hash.'"';

当我像上面那样使用单引号时，我所有的 html 代码都作为简单的文本打印在邮件中，没有正确的 html 格式。\r\n此外，我的标题在丢失后显示所有内容都搞砸了。

标题 2：

$headers = "From: webmaster@example.com\r\nReply-To: webmaster@example.com";
$headers .= "\r\nContent-Type: multipart/alternative; boundary=\"".$random_hash."\"";

使用这个，我得到了一个完美的标题，但现在我的邮件是空的，附件是空的。我不知道这是从哪里来的，因为我没有在邮件中附加任何内容。

请建议做什么

If you use single quotes on your PHP strings escape characters like \r\n will stop working.

I'm not sure how to help with your attachment without more context.

This is what I used before switching to phpmailer. As mentioned use a library.

// Make email headers
$separator = '--==Multipart_Boundary_'.md5(time());
$eol = PHP_EOL;

$filepath = "filename.pdf";
// open pdf file
$handle = fopen($filepath, "r");
// read pdf file
$f_contents=fread($handle,filesize($filepath));
// encode read pdf file
$attachment = chunk_split(base64_encode($f_contents));
// close pdf file
fclose($handle);
$message = "Text goes here";

// main header (multipart mandatory)
$headers = "MIME-Version: 1.0".$eol;
$headers .= "Content-Type: multipart/mixed; boundary=\"".$separator."\"".$eol;
$headers .= "Content-Transfer-Encoding: 7bit".$eol;
$headers .= "X-Priority: 1 (Highest)".$eol;
$headers .= "X-MSMail-Priority: High".$eol;
$headers .= "Importance: High".$eol;

// message
$headers .= "--".$separator.$eol;
$headers .= "Content-Type: text/plain; charset=utf-8".$eol;
$headers .= "Content-Transfer-Encoding: 8bit".$eol.$eol;
$headers .= $message.$eol;

// attachment
$headers .= "--".$separator.$eol;
$headers .= "Content-Type: application/pdf; name=".$filename.$eol;
$headers .= "Content-Transfer-Encoding: base64".$eol;
$headers .= "Content-Disposition: attachment; filename=".$filename.$eol.$eol;
$headers .= $attachment.$eol.$eol;
$headers .= "--".$separator."--";

If you're not actually defining two versions (plaintext/HTML) with multipart boundaries then you should change the Content-type: multipart/alternative to the proper content-type for your mail body.

Additionally, libraries like PHPMailer, et cetera are generally preferred over PHP's native mail() function because they offer a great deal more flexibility while not requiring you to manually construct complex headers.
