How to get difference of a time in seconds in PHP? - php

I have a database column with datatype "time" which stores 11:30:45. I have fetched this time in a variable say
$databasetime = 11:30:45
I want to declare a variable say $currenttime which will contain time just now. Like its 11:33:30 right now and another variable which will contain their difference in seconds like
$timediff = $currenttime - $databasetime;
echo $timediff;
I am trying $currenttime = time(); but I am not getting the result which I desire. I want $timediff = 165 but when I echo time(), I am getting a very big value.

$databasetime = strtotime('11:30:45');
$curtime = time();
echo $curtime - $databasetime;

You can do it in the following way:
$databasetime = '11:30:45';
$time1 = strtotime($databasetime);
$time2 = strtotime('now');
$diff = $time2 - $time1;
echo 'your difference: '.date('H:i:s', $diff);

$datetime1 = new DateTime('10:35:56 2013-11-17');
$datetime2 = new DateTime('10:35:50 2013-11-17');
$interval = $datetime1->diff($datetime2);
echo $interval->m . " Month " .$interval->d ." Days ". $interval->h . " Hours, " . $interval->i." Mintues, ".$interval->s." seconds <br/>";

<?php
$currentTime = time();
$futureDateTime = new DateTime('11:30:45'); // might want to specify a date and timezone, system TZ by default
$futureTime = $futureDateTime->format('U'); // get unix timestamp
$timeDiff = $futureTime-$currentTime;
?>

You use the DateTime 'OO' methods to return 'unix timestamp' integers directly
<?php
$now = new DateTime('now');
$date = new DateTime('11:30:45');
echo $now->getTimestamp() - $date->getTimestamp();
?>

Here is a simple example.
$databasetime = '11:30:45';
$timedif = abs(strtotime('now') - strtotime($databasetime));
echo $timedif; //echos the difference in seconds.
abs is used just to prevent neg numbers, which you may or may not want to do.

My problem is solved now. Actually all answers are right but the problem was due to the default time zone. I wanted Asia/Kolkata time zone but default European timezone apache was picking. That's why I was not getting my desired results.
So, I am finally using below code:
date_default_timezone_set('Asia/Kolkata');
$databasetime = strtotime('11:30:45');
$curtime = time();
echo $curtime - $databasetime;

PHP Current time in Hour:Minutes

I want to have have 2 variables with the current time in hours:minutes and also one that has +15 minutes. But first I must also add +6 hours.
So for example, right now it is 2018-01-07 16:35:10. So first I add +6 hours. So it will be 2018-01-07 22:35:10. Next, I want to extract only the hours:minutes.
I want to get only "22:35" to variable.
And next variable, I want 22:35 +15 minutes, so 22:50.
So I have $dateNow = 22:35 and $dateThen = 22:50
I have tried this so far to get current time now and +6 hours, but it's not working. Error: Call to a member function format() on integer
$now = strtotime(date("Y-m-d H:i:s")." +6 hours");
$then = $now->format('H:i');
echo $then;
i think in this case it would be very use full to use the DateTime class from PHP. The Problem with your code is strtotime returns a int not an DateTime object.
I've modified your code so it will work:
$org = new DateTime("2018-01-07 16:35:10");
$then = $org->add(new DateInterval("PT6H"));
echo $then->format("H:i"),"<br>";
$afterThen = $then->add(new DateInterval("PT15M"));
echo $afterThen->format("H:i");
Short solution with DateTime and DateInterval objects:
$now = new DateTime();
$result = $now->add(new DateInterval('PT6H15M'))->format('H:i');
Try this:
$time = time() + 3600 * 6; // add 6 hours
$date = date("H:i", $time); // format date
$date_plus_15 = date("H:i", $time + 60 * 15); // format date and add 15 minutes
echo "Time: {$date} <br>";
echo "Time + 15 mins: {$date_plus_15}";

PHP Minus time in Format

I want to keep the H:i:s format so 10:52:20 however when I try:
$timeleft = strtotime($time1)-strtotime($time2);
I get something like 4521
I would like the result to retain the format. Is there a way to do this?
Yeah, what you get is unix timestamp which is in seconds. You can use date function to get required format like this:
$timestr_formated = date("H:i:s", $timeleft);
print($timestr_formated);
You can use DateTime::diff.
$time1 = new DateTime('2017-05-01 12:00:00');
$time2 = new DateTime('2017-05-01 11:25:30');
$timeleft = $time1->diff($time2);
echo $timeleft->format('%H:%i:%s'); // output: 00:34:30
In case you want to allow more than 24 hours.
$time1 = new DateTime('2017-05-02 12:00:00');
$time2 = new DateTime('2017-04-02 11:25:30');
$timeleft = $time1->diff($time2);
echo str_pad($timeleft->format('%a') * 24 + $timeleft->format('%h'), 2, "0") .
$timeleft->format(':%i:%s'); // output: 720:34:30
You can use date function by below format:
$timeleft = date('H:i:s', strtotime($time1)-strtotime($time2));

add hours:min:sec to date in PHP

I am trying to add hh:mm:ss with the date. How can i do it?
I tried with the following but it works when the hour is string, but when adding time is similar to MySQL Date time it is not working.
$new_time = date("Y-m-d H:i:s", strtotime('+5 hours'));
I am trying to get solution for the following:
$timeA= '2015-10-09 13:40:14';
$timeB = '03:05:01'; // '0000-00-00 03:05:01'
OutPut:
$timeA + $timeB = 2015-10-09 16:45:15 ?
How Can I Add this?
Use DateInterval():
$timeA = new DateTime('2015-10-09 13:40:14');
$timeB = new DateInterval('PT3H5M1S'); // '03:05:01';
$timeA->add($timeB);
echo $timeA->format('Y-m-d H:i:s');
You would need to break your time down into the right DateInterval format but that is easily done with explode();
Here's how that might look:
$parts = array_map(function($num) {
return (int) $num;
}, explode(':', '03:05:01'));
$timeA = new DateTime('2015-10-09 13:40:14');
$timeB = new DateInterval(sprintf('PT%uH%uM%uS', $parts[0], $parts[1], $parts[2]));
$timeA->add($timeB);
echo $timeA->format('Y-m-d H:i:s');
Demo
print date('Y-m-d H:i:s',strtotime($timeA." +03 hour +05 minutes +01 seconds"));
Should work also.
So:
$timeA= '2015-10-09 13:40:14';
$timeB = vsprintf(" +%d hours +%d minutes +%d seconds", explode(':', '03:05:01'));
print date('Y-m-d H:i:s',strtotime($timeA.$timeB));
Can be the solution.
You may also convert the time into seconds with this approach from: Convert time in HH:MM:SS format to seconds only?
$time = '03:05:01';
$seconds = strtotime("1970-01-01 $time UTC");
Then you could add the seconds to
$currentTime = '2015-10-10 13:40:14';
$newTime = date("Y-m-d H:i:s", strtotime( $currentTime.'+'.$seconds.' seconds'));
If you prefer to use the DateTime objects offered by #John Conde, here are two ways to convert the time string into the format:
$formattedTime = preg_replace("/(\d{2}):(\d{2}):(\d{2})/","PT$1H$2M$3S","03:05:11");
or, as you read it from the database:
select concat(hour(last_modified),'H',minute(last_modified),'M',second(last_modified),'H') from people;
So a more general code approach would be:
$initial = 'some time';
$interval = 'the interval value';
$initialTime = new DateTime($initial);
$intervalTime = new DateInterval($interval);
$initialTime->add($intervalTime);
echo $initialTime->format('Y-m-d H:i:s');

Setting a time and date and adding to it in PHP

Basically am trying to set a time and a date in PHP then set a time gap which will range between minutes, loop through between a start time and end time echoing something out for each one. Have tried loads of different ways and cant seem to figure a way to set a date and add to it.
This seems the best script I have modified so far:
$minutes = 5;
$endtime = new DateTime('2012-01-01 09:00');
$newendtime = $endtime->format('Y-m-d H:i');
$timedate = new DateTime('2012-01-01 09:00');
while($stamp < $newendtime)
{
$time = new DateTime($timedate);
$time->add(new DateInterval('PT' . $minutes . 'M'));
$timedate = $time->format('Y-m-d H:i');
echo $timedate;
}
$minutes = 5;
$endtime = new DateTime('2012-01-01 09:00');
//modified the start value to get something _before_ the endtime:
$time = new DateTime('2012-01-01 8:00');
$interval = new DateInterval('PT' . $minutes . 'M');
while($time < $endtime){
$time->add($interval);
echo $time->format('Y-m-d H:i');
}
Do everything in seconds, and use php's time(), date(), and mktime functions.
In UNIX Time, dates are stored as the number of seconds since Jan 1, 1970.
You can render UNIX Timestamps with date().
$time = time(); // gets current time
$endtime = mktime(0,0,0, 1, 31, 2012); // set jan 31 # midnight as end time
$interval = 60 * 5; // 300 seconds = 5 minutes
while($time < $endtime){
$time += $interval;
echo date("M jS Y h:i:s a",$time) . "<br>"; // echos time as Jan 17th, 2012 1:04:56 pm
}
date reference:
http://us3.php.net/manual/en/function.date.php (includes superb date format reference too)
mktime reference: http://us2.php.net/mktime
time() only gets the current time, but just for kicks n' giggles: http://us2.php.net/time
And, it's super easy to store in a database!
This function will let you add date to your existing datetime. This will also preserves HH:MM:SS
<?php
function add_date($givendate,$day=0,$mth=0,$yr=0) {
$cd = strtotime($givendate);
$newdate = date('Y-m-d h:i:s', mktime(date('h',$cd),
date('i',$cd), date('s',$cd), date('m',$cd)+$mth,
date('d',$cd)+$day, date('Y',$cd)+$yr));
return $newdate;
}
?>
Usage:
add_date($date,12,0,0);
where $date is your date.

PHP: add seconds to a date

I have $adate; which contains:
Tue Jan 4 07:59:59 2011
I want to add to this date the following:
$duration=674165; // in seconds
Once the seconds are added I need the result back into date format.
I don't know what I'm doing, but I am getting odd results.
Note: both variables are dynamic. Now they are equal to the values given, but next query they will have different values.
If you are using php 5.3+ you can use a new way to do it.
<?php
$date = new DateTime();
echo $date->getTimestamp(). "<br>";
$date->add(new DateInterval('PT674165S')); // adds 674165 secs
echo $date->getTimestamp();
?>
Just use some nice PHP date/time functions:
$adate="Tue Jan 4 07:59:59 2011";
$duration=674165;
$dateinsec=strtotime($adate);
$newdate=$dateinsec+$duration;
echo date('D M H:i:s Y',$newdate);
Given the fact that $adate is a timestamp (if that's the case), you could do something like this:
$duration = 674165;
$result_date = strtotime(sprintf('+%d seconds', $duration), $adate);
echo date('Y-m-d H:i:s', $result_date);
// add 20 sec to now
$duration = 20;
echo date("Y-m-d H:i:s", strtotime("+$duration sec"));
Do this:
$seconds = 1;
$date_now = "2016-06-02 00:00:00";
echo date("Y-m-d H:i:s", (strtotime(date($date_now)) + $seconds));
$current_time_zone = 150;
date("Y-m-d H:i:s",strtotime(date("Y-m-d H:i:s"))+$current_time_zone);
I made this example for a timezone, but if you change some parts it may help you out:
$seconds_to_add = 30;
$time = new DateTime();
$time->setTimezone(new DateTimeZone('Europe/London'));
$time2 = $time->format("Y/m/d G:i:s");
$time->add(new DateInterval('PT' . $seconds_to_add . 'S'));
$timestamp = $time->format("Y/m/d G:i:s");
echo $timestamp;
echo '========';
echo $time2;
Result:
2018/06/17 3:16:23========2018/06/17 3:15:53
It would be easier with DateTime::modify
(new DateTime($str))->modify("+$duration seconds"); //$str is the date in string
I have trouble with strtotime() to resolve my problem of add dynamic data/time value in the current time
This was my solution:
$expires = 3600; //my dynamic time variable (static representation here)
$date = date_create(date('Y-m-d H:i:s')); //create a date/time variable (with the specified format - create your format, see (1))
echo date_format($date, 'Y-m-d H:i:s')."<br/>"; //shows the date/time variable without add seconds/time
date_add($date, date_interval_create_from_date_string($expires.' seconds')); //add dynamic quantity of seconds to data/time variable
echo date_format($date, 'Y-m-d H:i:s'); //shows the new data/time value
