Here are two functions to help you convert a number of seconds to something more friendly. Update: bug fix on seconds evaluating to more than one hour.
function secondsToFriendly($seconds) { ### this function takes a number of seconds and returns HH:MM:SS $st = $seconds; $s = 0; $m = 0; $h = 0; while ($st > 0) { if ($st < 60) { # only seconds left $s = $st; $st = 0; } else if ($st < 3600) { # minutes left $op = floor($st / 60); $m = $op; $st -= $op * 60; } else { # hours $op = floor($st / 3600); $h = $op; $st -= $op * 3600; } } # end of while return pad($h) .":". pad($m) .":". pad($s); } function pad($n, $pad = 2) { ### zero-pads a number $temp = ""; for ($i = 0; $i < $pad; $i++) { $temp .= "0"; } $temp .= $n; return substr($temp, strlen($temp) - $pad); }
