How to convert military time to a whole time in PHP? - php

Question

How to convert military time like this?
07:03 --> 07:30
06:45 --> 07:00
07:36 --> 08:00
19:15 --> 19:30
18:35 --> 19:00
19:35 --> 20:00
Basically the thing is, if the time is in the interval of 30 mins, you will add up the remaining minutes to make it a whole time.
In my database, I have to compare time like this where:
function check_range($get_shift, $date, $time, $id, $mode) {
$sql = "SELECT * FROM tbl_employee WHERE id = '$id'";
$result = mysql_query($sql);
$row_check_range = mysql_fetch_assoc($result);
$getShift = $row_check_range['shift'];
$sql2 = "SELECT * FROM tbl_shift WHERE shift = '$getShift'";
$result2 = mysql_query($sql2);
$row_check_range2 = mysql_fetch_assoc($result2);
$getTimeShift = $row_check_range2['timeIn'];
$actual_time_in_mode = explode(':', $time); //split time into (e.g 07, 11)
if ($mode == 'AM') {
$time_in_actual = $actual_time_in_mode[0];
} else {
$time_in_actual = $actual_time_in_mode[0];
$time_shift = explode(':', $getTimeShift);
$getTimeShift = $time_shift[0] + 12; //convert to military time
}
$getTimeShift = mktime($getTimeShift);
$actual_in_mode = mktime($time);
if ($actual_in_mode > $getTimeShift) // LATE
{
return $date.' '.$time_in_actual.':30:00';
} else {
$time_in_actual += 1;
return $date.' '.$time_in_actual.':00:00';
}
}

Answer 1

Something like this should do.
list($hour, $minute) = explode(':', $time);
if ($minute > 30) {
$hour++;
$minute = 0;
} elseif ($minute > 0) {
$minute = 30;
}
if ($hour == 24) $hour = 0;
printf('%02d:%02d', $hour, $minute);

Answer 2

function military_time($x){
$y=split(':',$x);
$y[0] =(((int)$y[1]) >30) ? ((int)$y[0])+1 : $y[0];
$y[0] =((int) $y[0] == 24) ? '00':$y[0];
$y[0]=(strlen($y[0]) == 1) ? '0'.$y[0] : $y[0];
$y[1] =(((int)$y[1]) >30) ? '00':'30';
echo $y[0].':'.$y[1];
}
military_time('23:35');

Just add 30 minutes and then round the number DOWN to the closest :30 or :00.
