$course_hour = 1; $starttime = '07:00'; $endtime = '16:00';
I wish if it could return an array of values like below: If
$course_hour = 1;
$return_array = array('07:00 - 08:00', '08:00 - 09:00', '09:00 - 10:00', '10:00 - 11:00', '11:00 - 12:00', '12:00 - 13:00', '13:00 - 14:00', '14:00 - 15:00', '15:00 - 16:00'); If
$course_hour = 1.5;
$return_array = array('07:00 - 08:30', '8:30 - 10:00', '10:00 - 11:30', '11:30 - 13:00', '13:00 - 14:30', '14:30 - 16:00'); If
$course_hour = 2;
$return_array = array('07:00 - 09:00', '09:00 - 11:00', '11:00 - 13:00', '13:00 - 15:00');
function get_session_times($course_hour, $start_time, $end_time){
if(strlen($start_time) < 5) $start_time = '0'.$start_time;
if(strlen($end_time) < 5) $end_time = '0'.$end_time;
$current_time = date("Y-m-d H:i");
$session_starttime = date("Y-m-d H:i", strtotime(date("Y-m-d ").$start_time));
$session_endtime = date("Y-m-d H:i", strtotime(date("Y-m-d ").$end_time));
$session_starttime_ms = strtotime($session_starttime);
$session_endtime_ms = strtotime($session_endtime);
$session_times_array = array();
for ($i = $session_starttime_ms; $i < $session_endtime_ms; ) {
$session_times_array[] = date("H:i", $i)."<br/>";
$i = $i ($course_hour * 60 * 60);
}
return $session_times_array;
}

You have to convert from decimal (for example 1
, 1.5
) to be hour and minute based on code from this answer.
And then I use code from this answer mentioned by mickmackusa to get times array.
Here is testing.
/**
* This function is for test the result only. It is no need in your real project.
*/
function testResult($result, $expect)
{
if (!is_array($result) || !is_array($expect)) {
throw new Exception('The result and expect must be array.');
}
$totalResult = count($result);
$totalExpect = count($expect);
$totalTested = ($totalResult === $totalExpect);
unset($totalResult, $totalExpect);
foreach ($result as $index => $eachResult) {
if (isset($expect[$index]) && $expect[$index] === $eachResult) {
// matched.
} else {
throw new Exception('The result and expect at index ' . $index . ' does not matched. (' . $eachResult . ')');
}
}
return $totalTested;
}
// run tests
$result = getSessionTimes(1, '07:00', '16:00');
$expect = ['07:00 - 08:00', '08:00 - 09:00', '09:00 - 10:00', '10:00 - 11:00', '11:00 - 12:00', '12:00 - 13:00', '13:00 - 14:00', '14:00 - 15:00', '15:00 - 16:00'];
print_r($result);
var_dump(testResult($result, $expect));
$result = getSessionTimes(1.5, '07:00', '16:00');
$expect = ['07:00 - 08:30', '08:30 - 10:00', '10:00 - 11:30', '11:30 - 13:00', '13:00 - 14:30', '14:30 - 16:00'];
print_r($result);
var_dump(testResult($result, $expect));
$result = getSessionTimes(2, '07:00', '16:00');
$expect = ['07:00 - 09:00', '09:00 - 11:00', '11:00 - 13:00', '13:00 - 15:00'];
print_r($result);
var_dump(testResult($result, $expect));
The result will be...
