php - Calculate the hours minutes and days of difference between two date and hours

Question

I have a PHP and MySQL code that should calculate the hours minutes and days of difference between two date and hours. It works well, just adding 20 hours and 20 minutes more than normal. And I remove the DATE part and put the date and time manually, it works fine.

I don't understand what happens.

    $fecha = $row["fecha"];
        $data= $row["hora"];
$start = strtotime("$fecha $hora"); 


$currentDate = date("Y-m-d");
$currentTime = date("H:i:s");
$currentDate =  date("Y-m-d H:i:s", strtotime($currentDate .$currentTime));

$end = strtotime("$currentDate"); 



$totaltime = ($end - $start)  ; 

$hours = intval($totaltime / 3600);   
$seconds_remain = ($totaltime - ($hours * 3600)); 

$minutes = intval($seconds_remain / 60);   
$seconds = ($seconds_remain - ($minutes * 60));
$statusfichaje= $row["status"];
if ($statusfichaje == Start){echo '<td>Trabajando'.$hours.':'.$minutes.':'.$seconds.' </td>';}else{echo '<td>'. $row["status"] .'</td>';}

Edit

start 2019-12-29 21:27:50 . end 2019-12-31 0:51:50 = 47:51:16

As you can see it calculates badly.

Answer 1

A simple example like this would do the job :

$mydatetime = new DateTime();
$datefromdb = new DateTime('2018-03-05 10:10:00');
$interval = $mydatetime->diff($datefromdb);
$date_count = $interval->format('%y years %m months %a days %h hours %i minutes %s seconds');
echo $date_count;

This is your code it should work

$fecha = $row["fecha"];
$data= $row["hora"];
$start = strtotime("$fecha $data"); 


$currentDate = date("Y-m-d");
$currentTime = date("H:i:s");
$currentDate =  date("Y-m-d H:i:s", strtotime($currentDate .$currentTime));

$end = strtotime("$currentDate"); 



$totaltime = ($end - $start)  ; 

$hours = intval($totaltime / 3600);   
$seconds_remain = ($totaltime - ($hours * 3600)); 

$minutes = intval($seconds_remain / 60);   
$seconds = ($seconds_remain - ($minutes * 60));
$statusfichaje= $row["status"];
if ($statusfichaje == $start){echo '<td>Trabajando'.$hours.':'.$minutes.':'.$seconds.' </td>';}else{echo '<td>'. $row["status"] .'</td>';}
