How can using ISO date format improve the compatibility of PHP code across different systems?

Using the ISO date format (YYYY-MM-DD) ensures that dates are consistently formatted across different systems, making it easier for PHP code to interpret and manipulate dates accurately. This format is recognized universally and eliminates any ambiguity that may arise from different date formats used in different regions or systems. 

$date = date('Y-m-d', strtotime('2022-12-31'));
echo $date;
