PHP add up two time variables

How to sum up time in php.
For example I have this series of time duration logs:
00:10:00
00:30:10
01:00:50
The total should be 1 hour and 41 minutes
Here is my code:
$log_in = new DateTime($log->log_in);
$log_out = new DateTime($log->log_out);
$diff = $log_out->diff($log_in);
$total += strtotime($diff->format('%H:%i:%s'));
echo $diff->format('%H:%i:%s');
Convert the time into timestamp using strtotime() function. Then manipulate the time according your need and get result in terms of seconds.
Once you get seconds.
For Hour
$hour = $diff % 3600
For Minute
$Minute = ($diff - ( $hour *3600))%60;

Subtract time in PHP
(3 answers)
Closed 3 years ago.
I am looking to get the previous increment of five minutes from the current time...
Lets say that the current time is 12:07pm UTC
I want to put into a variable 12:05pm UTC
What would be an easy way of going about this?
You can do this with the DateTime class (https://3v4l.org/7aqMH):
<?php
$date = new DateTime('12:07 UTC');
$minutes = (int) $date->format('i');
$rounded = round($minutes / 5) * 5;
$date->setTime($date->format('H'), $rounded, $date->format('s'));
or more concisely:
<?php
$date = new DateTime('12:07 UTC');
$date->setTime(
$date->format('H'),
round($date->format('i') / 5) * 5,
$date->format('s')
);
There's nothing built in that allows you to retrieve 'increments' however you can calculate it with minimal code. The use of modulo here allows you to figure out how far past the most recent 5 minute mark is. It will never be greater than 5 minutes (300 seconds) and can always be subtracted safely to take you back to the time you want.
$now = time();
echo $now . PHP_EOL;
$five_minutes = 60*5; // 300
$offset = $now % $five_minutes;
$five_block = $now - $offset;
echo date('Y-m-d H:i:s', $five_block);
First you will want to extract the minutes from their stored variable. Then mathematically this is simple by applying division and the floor function. To do this you can first divide by five using intdiv(numerator, denominator) which will remove any trailing decimal points and then multiply by five again to get your desired value at an increment of five.
Get the current time using time() :
$min = 300
$currentTime = time();
$mod = $currentTime % $min;
$res = $currentTime - $mod;
finalResult = date('Y-m-d H:i:s', $res);

Converting string to Date and DateTime
(13 answers)
Closed 8 years ago.
I get the string data from the database
The data format like:
07:00:00.0000000
It means 7:00 am.
How can i convert this string into Date type for comparison.
Therefore, I can get 2 data. Such as
Start:
07:00:00.0000000
End:
16:30:00.0000000
After the time comparison, i can got a answer like 9.3.
You can use strtotime :
$start = strtotime("07:00:00.0000000");
$end = strtotime("16:30:00.0000000");
$difference = $end - $start;
Or with DataTime object :
$start = new DateTime("07:00:00.0000000");
$end = new DateTime("16:30:00.0000000");
$interval = $start->diff($end);
$difference = $end->getTimestamp() - $start->getTimestamp();
Then echo the result :
echo $difference; // in seconds
echo $difference / 60; // in minutes
echo $difference / 3600; // in hours
echo $interval->format('%s') // in seconds
It's then up to your preference. I also suggest you to have a look at this post regarding the performances of the two solutions.

PHP calculate days Between 2 different dates [duplicate]
(2 answers)
Closed 9 years ago.
$1date =$row['Date1'];
$2date = $row['Date2'];
$datediff = $1date - $2date;
echo $datediff;
I want to count the days between and put into a table the result(10 dollars for each day passed)
// convert to unix timestamp
$1date = strtotime($row['Date1']);
$2date = strtotime($row['Date2']);
// 86400 seconds in a day
// floor to round down, change to ceil to round up
$datediff = floor(($1date - $2date) / 86400);
$cost = $days * 10;
You could do it in MySQL then work it into a variable. Do the initial call
SELECT TIMESTAMPDIFF('Date1','Date2');
Try:
$days = date_diff(date_create($row['Date1']), date_create($row['Date2']))->format('%a');
$cost = $days * 10;

Calculate number of hours between 2 dates in PHP
How can I get the number of hours of difference between two dates in PHP? I need to get an integer since I want to know if is bigger or smaller than a particular value.
Try:
$date1 = "2012-11-05 12:35:00";
$date2 = "2012-11-07 14:35:00";
$diff = strtotime($date2) - strtotime($date1);
$diff_in_hrs = $diff/3600;
print_r($diff_in_hrs);
Manual
Demo
If you have an up-to-date PHP
$dateOne = new DateTime('2012-01-20 00:00:00');
$dateTwo = new DateTime('2012-01-21 02:00:00');
// Procedurally
$interval = date_diff($dateOne, $dateTwo);
// Alternatively OOP style if supported
$interval = $dateOne->diff($dateTwo);
See: http://www.php.net/manual/en/class.dateinterval.php
<?php
$time1 = time();
$time2 = mktime(0,0,0,11,13,2012); // earlier today
echo ($time1 - $time2) / 3600; // 3600 seconds in hour
?>

Get interval seconds between two datetime in PHP?
(8 answers)
Closed last month.
In my project, I need to calculate the difference in seconds between two dates:
For example:
$firstDay = "2011-05-12 18:20:20";
$secondDay = "2011-05-13 18:20:20";
Then I should get 86400 Seconds That is 24 hours.
Similarly for
$firstDay = "2011-05-13 11:59:20";
$secondDay = "2011-05-13 12:00:20";
It should return 60 Seconds.
I read lots of questions on Stack Overflow but they only deal with the difference between 2 minute fields like 11:50:01 and 12:10:57
$timeFirst = strtotime('2011-05-12 18:20:20');
$timeSecond = strtotime('2011-05-13 18:20:20');
$differenceInSeconds = $timeSecond - $timeFirst;
You will then be able to use the seconds to find minutes, hours, days, etc.
