I needed that before I found this script here, so I`ve written my own functions. I didn`t like the idea "if this is greater than 60 then...".
In case anyone needs it, here`s my two functions:
function TimeToMinutes($timestring)
{
$retval = 0;
if (preg_match("/(\d{1,}):(\d{1,})/", $timestring, $parts))
{
$retval = $parts[1] * 60 + $parts[2];
}
return $retval;
}
function MinutesToTime($minutenstring)
{
$retval = "";
$minuten = $minutenstring % 60;
$stunden = ($minutenstring - $minuten) / 60;
$retval = $stunden . ":" . sprintf("%02d", $minuten);
return $retval;
}
I convert the two time strings to minutes, add them and convert them back. The times are stored as minutes in the database, in order to calculate some statistics via SQL-queries. The format hh:mm is just used for the frontend.
