Comparing times in the 12-hour format

Can someone help and give a solution to compare two times which are in the following format when received: 12:20 AM.

I have two time fields in my script which are meant to be stored in the database after validation, but after validation that the format is in correct order i want to do comparison between those two fields.

The comparison i want to do is to check if the second field not overlapping the first one.

For Example:

The first variable is named $timeStart, and holding the time value of = "05:30 PM".

The second is named $timeEnd, holding a value of = "4:00 PM".

Now, i want to do a comparison to see if the $timeEnd is before $timeStart (also putting into consideration AM/PM when comparing) if it is i dont want to echo an error, otherwise continue with the script.

I'm doing it for a Event Script, so timing has to be right :) $timeEnd has to be after $timeStart.

I sure do hope i explained it clear enough :( Thanks for taking the time to read my complicated gibberish :)

This should help

function timediff($start, $end)
{
        if($end >= $start)
        {
            return (round(($end-$start)/3600, 0))." Hrs ".((($end-$start)%3600)/60)." Min";
        }
        return false;
}
echo timediff(strtotime('yesterday 5 pm'), strtotime('today 4:30 am'));

if(function greaterDate($start_date,$end_date)
{

  $start = strtotime($start_date);
  $end = strtotime($end_date);
      if ($start-$end > 0)
       return 1;
     else
       return 0;
}
$time = greaterDate($start_date,$end_date))

if (strtotime($timeEnd) < strtotime($timeStart)) {
    // fail
}

Only makes sense though if you're not going to allow day crossovers, obviously.
