What are the potential pitfalls of using different versions (1.0 vs. 2.0) in generating iCalendar files with PHP for Outlook?

When generating iCalendar files with PHP for Outlook, using different versions (1.0 vs. 2.0) can lead to compatibility issues and incorrect rendering of events. To ensure proper functionality, it is recommended to stick to a specific version (preferably 2.0) when generating iCalendar files for Outlook. 

// Specify the iCalendar version as 2.0
$ical_data = "BEGIN:VCALENDAR\r\n";
$ical_data .= "VERSION:2.0\r\n";
$ical_data .= "PRODID:-//Your Company//NONSGML Calendar//EN\r\n";
// Add event details here
$ical_data .= "END:VCALENDAR\r\n";

// Set the appropriate headers for the iCalendar file
header('Content-type: text/calendar; charset=utf-8');
header('Content-Disposition: attachment; filename=calendar.ics');

// Output the iCalendar data
echo $ical_data;
