I would like to send an invitation to a meeting in php.
I managed to create a .ics file that can be integrated into Zimbra, but I do not know how to create the invitation as it can be done in Zimbra.
Code: Select all
<?php
$from_name = "webmaster";
$from_address = "webmaster@example.com";
$to_name = "Anthony";
$to_address = "antho@test.com";
$startTime = "15/02/2018 18:00:00";
$endTime = "15/02/2018 19:00:00";
$subject = "My Test Subject";
$description = "My Awesome Description";
$location = "Joe's House";
sendIcalEvent($from_name, $from_address, $to_name, $to_address, $startTime, $endTime, $subject, $description, $location);
function sendIcalEvent($from_name, $from_address, $to_name, $to_address, $startTime, $endTime, $subject, $description, $location)
{
$domain = 'exchangecore.com';
//Create Email Headers
$mime_boundary = "----Meeting Booking----".MD5(TIME());
$headers = "From: ".$from_name." <".$from_address.">\n";
$headers .= "Reply-To: ".$from_name." <".$from_address.">\n";
$headers .= "MIME-Version: 1.0\n";
$headers .= "Content-Type: multipart/alternative; boundary=\"$mime_boundary\"\n";
$headers .= "Content-class: urn:content-classes:calendarmessage\n";
//Create Email Body (HTML)
$message = "--$mime_boundary\r\n";
$message .= "Content-Type: text/html; charset=UTF-8\n";
$message .= "Content-Transfer-Encoding: quoted-printable\n\n";
$message .= "<html>\n";
$message .= "<body>\n";
$message .= '<p>Dear '.$to_name.',</p>';
$message .= '<p>'.$description.'</p>';
$message .= "</body>\n";
$message .= "</html>\n";
$message .= "--$mime_boundary\r\n";
