Am creating a timetable system and i want to check only the time difference

 

Am collect a time only from the html form thus

$startTime = 13:30:00

$endTime = 14:00:00

Use DateTime class.

$startTime = '13:30:00';
$endTime = '14:00:00';

$dt1 = new DateTime($startTime);
$dt2 = new DateTime($endTime);
$diff = $dt1->diff($dt2);
echo $diff->format('%h:%I'); //--> 0:30
