使用php脚本将事件添加到Outlook日历

<?PHP
header("Content-Type: text/Calendar");
header("Content-disposition: inline; filename=calendar.ics");
echo "BEGIN:VCALENDAR\n";
echo "VERSION:2.0\n";
echo "PRODID:www.testMeiCalendar.net\n";
echo "METHOD:REQUEST\n"; // requied by Outlook
echo "BEGIN:VEVENT\n";
echo "DTSTART:20101231T230000\n";
echo "DTEND:20110101T010000\n";
echo "SUMMARY:New Years Eve Reminder\n";
echo "LOCATION:Downtown\n";
echo "DESCRIPTION:Let's get together for New Years Eve\n";
echo "UID:ABCD1234\n";
echo "SEQUENCE:0\n";
echo "DTSTAMP:20101125T112600\n";
echo "END:VEVENT\n";
echo "END:VCALENDAR\n";
?>

所以现在当我在Firefox中运行此代码时,我得到一个弹出窗口,要求使用Microsoft Outlook打开生成的ics文件,然后打开它并将其保存到Outlook,最后在Outlook中添加了一个事件.

但有没有办法让这个过程自动化？我的意思是,我可以直接从PHP脚本将事件存储在Outlook日历中,而无需生成ics文件并保存吗？
