What is the significance of keeping the line length under 75 characters in an ical file?

Keeping the line length under 75 characters in an iCal file is important to ensure compatibility with various email clients and systems that may have limitations on the maximum line length they can handle. To solve this issue, you can use PHP's wordwrap function to break up long lines into shorter ones. 

$long_line = "This is a long line that needs to be wrapped to stay under 75 characters in an iCal file.";
$wrapped_line = wordwrap($long_line, 75, "\r\n ");

echo $wrapped_line;
