In the last example, conversion from seconds to Hour, Minutes, Seconds is wrong.
This is the correct verion:

<?php
$si 
date_sun_info(strtotime('2022-08-26'), 50.4530.52);
$diff $si['sunset'] - $si['sunrise'];  # $diff is measured in seconds.
echo "Length of day: ",
   
floor($diff 3600), "h",
   
floor(($diff 3600) / 60), "m",
   
floor($diff 60), "s\n";
?>

Output:
  Length of day: 13h53m15s
