PHP HTML-Email结果中的感叹号随机出现

Question

我在PHP电子邮件功能的结果中随机出现惊叹号.我读到这是因为我的线太长或者我不得不在Base64中对电子邮件进行编码,但我不知道该怎么做.

这就是我所拥有的:

$to = "you@you.you";
$subject = "Pulling Hair Out";
$from = "me@me.me";
$headers = "From:" . $from;
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
$headers .= "Content-Transfer-Encoding: 64bit\r\n";

mail($to,$subject,$message,$headers); 

我该怎么解决这个问题,所以没有随意的!在结果？谢谢!

Answer 1

如下所述:HTML电子邮件中的感叹号

问题是你的字符串太长了.将超过78个字符的HTML字符串提供给邮件功能,最终会得到一个!(砰)在你的字符串中.

这是由于RFC2822中的行长度限制http://tools.ietf.org/html/rfc2822#section-2.1.1

Answer 2

尝试使用这段代码:

$to = "you@you.you";
$subject = "Pulling Hair Out";
$from = "me@me.me";
$headers = "From:" . $from;
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
$headers .= "Content-Transfer-Encoding: 64bit\r\n";

$finalMessage = wordwrap( $message, 75, "\n" );

mail($to,$subject,$finalMessage,$headers);

问题是一行不应超过998个字符.(另请参见/sf/answers/898823691/)
