get the difference in time between two given time - php

Question

I'm trying to get the difference in time between two given times e.g. first time '17:00:01' and then second time '17:47:25' and here's what I tried so far,
$start_time = "17:00:01";
$end_time = "17:47:25";
echo $start_time->diff($end_time);
But seem's unfortunately not working, any help, ideas please?
My expected output must be like, if no difference in hours but there's difference in minutes and seconds then, "22 mins and 15 secs", If no difference in minutes but have difference in hours then, "2 hrs and 10 secs" but if only seconds in difference then, "22 secs".

Answer 1

Get difference between two times
public function convTimeToMinutes($intime, $outtime)
{
$start = Carbon::parse($intime);
$end = Carbon::parse($outtime);
$minutes = $end->diffInMinutes($start); // 226
return $this->convertMinuteToHours($minutes);
}
public function convertMinuteToHours($minutes)
{
return $minutes / 60;
}
$totalHour = $this->convTimeToMinutes('09:25:35', '13:12:27');
//$totalHour = 3.76

String in php is not object, so can't call diff method on it.
Use diff method, you must change the string to DateTime object.
If you want to compare time difference in same day, you could try:
$start_time = "17:00:01";
$end_time = "17:47:25";
$start_datetime = new DateTime(date('Y-m-d').' '.$start_time);
$end_datetime = new DateTime(date('Y-m-d').' '.$end_time);
var_dump($start_datetime->diff($end_datetime));

Answer 3

Here is it.
PHP
$start_time = "17:00:01";
$end_time = "17:47:25";
$time1 = new DateTime($start_time);
$time2 = new DateTime($end_time);
$interval = $time1->diff($time2);
echo $hour = $interval->format('%h hour');
echo $min = $interval->format('%i min');
echo $sec = $interval->format('%s second');
Output:
0 hour 47 min 24 sec
Now you can add some condition and make the real format.

Just another way of doing it using string functions:
/*
* Get difference in seconds between time formats
*/
function getDiff($start_time, $end_time)
{
$start_time = timeFormatToSeconds($start_time);
$end_time = timeFormatToSeconds($end_time);
if ($end_time > $start_time) {
return $end_time - $start_time;
}
return false;
}
/*
* Convert time format (HH:MM:SS) to seconds
*/
function timeFormatToSeconds($time_format)
{
sscanf($time_format, "%d:%d:%d", $hours, $minutes, $seconds);
return $hours * 3600 + $minutes * 60 + $seconds;
}
$start_time = "17:00:01";
$end_time = "17:47:25";
$diff = getDiff($start_time, $end_time);
if ($diff) {
$hours = floor($time / (60 * 60));
$time -= $hours * (60 * 60);
$minutes = floor($time / 60);
$time -= $minutes * 60;
$seconds = floor($time);
$time -= $seconds;
var_dump(array($hours, $minutes, $seconds));
}

Answer 5

Convert string time to timestamp and subtract. Convert timestamp to desired time format.
$start_time = strtotime('17:00:01');
$end_time = strtotime('17:47:25');
$diff = $end_time - $start_time;
echo date('H:i:s', $diff);

Answer 6

You can do something like this as a generic function
private function calculateDiffInMinutes($from, $to)
{
$from = Carbon::createFromFormat('Y-m-d H:s:i', $from);
$to = Carbon::createFromFormat('Y-m-d H:s:i', $to);
return $to->diffInMinutes($from);
}
and you can call the function anywhere and pass the parameters you need
here the difference between now and created at time
$this->calculateDiffInMinutes($item->created_at, now())
Hope this helped
