What are common issues encountered when generating iCal files with PHP and how can they be resolved?

Issue: Incorrect timezone in iCal file generated by PHP. Solution: Set the correct timezone in the iCal file by using the 'DTSTART;TZID' property. 

<?php
// Set the timezone
$timezone = 'America/New_York';

// Generate iCal file with correct timezone
$ical = "BEGIN:VCALENDAR
VERSION:2.0
PRODID:-//Example Corp.//iCal Event//EN
BEGIN:VEVENT
DTSTART;TZID=$timezone:20230101T080000
SUMMARY:New Year's Day
END:VEVENT
END:VCALENDAR";

// Output the iCal file
header('Content-type: text/calendar; charset=utf-8');
header('Content-Disposition: attachment; filename=calendar.ics');
echo $ical;
?>
