我在使用 PHPMailer 时遇到了一些奇怪的问题。我正在尝试发送一些使用 PHP 生成的 HTML 和纯文本内容，但正文被截断。更奇怪的是，这仅发生在我生成的电子邮件中，如果我在其中放入一些更长的通用内容，它会被正确发送。我还必须提到，我确实回显了变量$content和$nohtmlcontent变量的内容，并且一切都像它应该的那样，但是当我在邮箱中收到电子邮件时，它被截断了。
我用于创建纯文本和 HTML 电子邮件正文的 PHP 代码：
$content="<BODY bgColor=\"#ffffff\"><FONT face=\"Verdana\" size=\"2\">";
$content.="Hello $name.<br /><br />Administrator of <a href=\"http://$url\">$url</a> has created a new account for you.<br /><br />Your new account details:<br />";
$content.=$message."<br /><br />";
$content.="If you see something wrong, please reply with correct details and we will update your account.<br /><br />";
$content.="Have a nice day,<br />$url</FONT></FONT></BODY>";
$nohtmlcontent="Hello $name.\n\nAdministrator of $url has created a new account for you.\n\nYour new account details:\n\n";
$nohtmlcontent.=$usrEmail."\n\n";
$nohtmlcontent.="If you see something wrong, please reply with correct details and we will update your account.\n\n";
$nohtmlcontent.="Have a nice day,\n$url";
所有变量都填充了适当的数据。
我用于发送电子邮件的 PHPMailer 代码：
require_once("class.phpmailer.php");
$mail=new PHPMailer(true);
try {
$mail->AddAddress($email);
$mail->SetFrom('admin@example.com', 'example.com');
$mail->CharSet = 'UTF-8';
$mail->Subject = "New account for you";
$mail->IsHTML(true);
$mail->AltBody = $nohtmlcontent;
$mail->Body = $content;
$mail->Send();
return true;
}catch(phpmailerException $e){
trigger_error("PHPMailer failed: ".$e->errorMessage());
return false;
}
结果：

请注意最后的额外内容。
我也尝试过使用 PHP 的函数mail()来发送相同的内容，它也会被截断。
有任何想法吗？
SOLUTION: PHP代码生成的行很长，添加几个换行符后，完整的内容就通过了。
