PHP-parser for 3 ics-files (ICS->HTML)

Hi, I've got 3 ics-files with events (calendar). The ICS-content is provided via URL. So I've got 3 URLS, where I can download a ICS-File. The content changes often. I don't have static ics-files. I use the URl and get the latest ics-file. I need a script (PHP) to read all the events (from all ics-files) and put them into ONE list (order by date). Output should be: #startdate, #starttime - #endtime (only if exist endtime) #description, #summary Input (ics-files) is: BEGIN:VCALENDAR VERSION:2.0 PRODID:**** METHOD:PUBLISH CALSCALE:GREGORIAN X-MICROSOFT-CALSCALE:GREGORIAN X-WR-CALNAME:**** X-PUBLISHED-TTL:P1W BEGIN:VEVENT UID:19_8 DTSTART:20180923T080000Z SEQUENCE:1 TRANSP:OPAQUE DTEND:20180923T100000Z URL:*** LOCATION:Location SUMMARY:Here my event CLASS:PUBLIC DESCRIPTION:here my description ORGANIZER:MAILTO:*** DTSTAMP:20181008T145352Z CREATED:20180809T184036Z LAST-MODIFIED:20180809T184630Z END:VEVENT The list should contain the next 10 events. Amount of events (10) should be saved in a variable, so that I can change it easily later. Also it should be possible to add one or two more ics-files (URLs) later. The script should handle utf8-letters.
