Question

I want to figure out the difference in time by seconds. I keep getting 0 as a results and wants to know if someone could assist me. The times will be pulled from a database.

Here is an example of what I want to be able to do.

$TimeStart = "04:30:45 am";
$TimeEnd = "04:31:46 am";
$Difference = $TimeEnd - $TimeStart . "seconds";

I know this is not a very illustrated example and I know it is probably not that simple.

Here is the code that is currently on my site now:

$TimeStart = strtotime($VisitsRow['TimeStart']);
$TimeEnd = strtotime($VisitsRow['TimeEnd']);
$TimeDifference = ($TimeEnd - $TimeStart);
if ($VisitsRow['TimeEnd'] == "") {
    $Timeto = "Incomplete";
} else {
    if ($TimeDifference <= 60) {
        $Timeto = "< a minute";
    } else if ($TimeDifference <= 0) {
        $Timeto = "< a second";
    } else {
        $Timeto = round($TimeDifference, 2)." seconds";
    }
    if ($TimeDifference >= 60) {
        $MinutesDiff = $TimeDifference / 60;
        $Timeto = round($MinutesDiff, 2)." minutes";
    }
}

I have simply tried the example of what I want above and am getting a negative number. This is why I am needing assistance.

Thank you everyone for helping me solve this. My problem was that it was gathering the times in 24 hr format and not the standard. Once I solved this everything works perfectly.
