在 php 中通过电子邮件附加/发送 .ics 事件

Question

我在尝试通过电子邮件发送 .ics 文件时遇到问题 'meeting invitation'。

我正在使用这个 class 来快速生成 .ics 文件的内容： https://gist.github.com/jakebellacera/635416

内容生成正确，但我无法将其显示为附件...目前仅显示为字符串。

我什至尝试对其进行编码，但它只是将编码后的 .ics 内容显示为字符串。

这是我目前的代码：

// CREATE ICAL INVITE
include("ICS.php");

//header('Content-Type: text/calendar; charset=utf-8');
//header('Content-Disposition: attachment; filename=cita.ics');

$location = "Barcelona";
$mdesc = "Cita Masaje";
$mname= "$name - $phone";
$meetURL = "redacted";

$props = array(
    'location' => $location,
    'description' => $mdesc,
    'dtstart' => $dateStart,
    'dtend' => $dateEnd,
    'summary' => $mname,
    'url' => $meetURL
);

$ics = new ICS($props);
$ical = $ics->to_string();
$boundary = md5("random"); // define boundary with a md5 hashed value

$recipient = "redacted";
$subject = "Nuevo contacto de $name - $email";
//header
$mailheaders = "From: ".$name." <".$email.">\n";
$mailheaders .= "Reply-To: ".$name." <".$email.">\n";
$mailheaders .= "MIME-Version: 1.0\n";
$mailheaders .= "Content-Type: multipart/mixed;\n";
$mailheaders .= "boundary = $boundary\r\n"; //Defining the Boundary

//attachment
$formcontent = "--$boundary\r\n";
$formcontent .= "De: $name - $email\nTel: $phone\nCita: $dateStart\nAcaba: $dateEnd\nMensaje:\n\n$message\n\n";

$formcontent .= "--$boundary\r\n";
$encoded_content = chunk_split(base64_encode($ical));

$formcontent .="Content-Disposition: attachment";
$formcontent .="Content-Transfer-Encoding: base64";
//$formcontent .= "Content-Transfer-Encoding: 8bit\n\n";
//$formcontent .='Content-Type: text/calendar; name="cita.ics"; method=REQUEST\n';
$formcontent .="Content-Type: application/octet-stream; name='cita.ics'; method=REQUEST\n";
$formcontent .="X-Attachment-Id: ".rand(1000, 99999)."\n";
$formcontent .= $encoded_content; // Attaching the encoded file with email

// Send email notification
if(mail($recipient, $subject, $formcontent, $mailheaders)) {
    // send auto-reply
    mail($email, $rplysubject, $reply, $rplyheader) or die("Error!");
} else {
    die("Error!");
}
echo "Muchas gracias $name! Tu mensaje ha sido enviado.";

注释掉了一些我尝试过的东西...下面是自动回复电子邮件的当前结果：

过去我也尝试过 mail->addAttachment() 或 ->addStringAttachment() 但这两个调用都破坏了我的代码。

这是非编码 ics 事件的样子：
