Should you want to convert between HH:MM:SS and plain seconds like in MySQL, these functions should do the trick:
<?php
function time_to_sec($time) {
$hours = substr($time, 0, -6);
$minutes = substr($time, -5, 2);
$seconds = substr($time, -2);
return $hours * 3600 + $minutes * 60 + $seconds;
}
function sec_to_time($seconds) {
$hours = floor($seconds / 3600);
$minutes = floor($seconds % 3600 / 60);
$seconds = $seconds % 60;
return sprintf("%d:%02d:%02d", $hours, $minutes, $seconds);
}
?>
