how to calculate elapsed time between dates from a table? in pho-CodePudding

I want to know how to calculate the difference between timestamps presented in a table, for example, if in the first field I have "2022-07-23 13:10:11" and in the second field I have "2022-07-23 13:15: 11" I would like to know the time elapsed between those times, for example it would only be 5 min but in the third field I have "2022-07-24 13:15:11", the difference between 2 and 3 would be 1 day, for that time data elapsed would be a new column, but I want to know if it could be done, I have investigated and there is the date_diff function but I do not understand how to use it to do it in a table since a for would be used

To calculate the elapsed time between two dates from a datetime string in PHP, you can use the DateTimeImmutable class and its diff method. The DateTimeImmutable class allows you to create objects that represent a specific date and time. The diff method can be used to calculate the difference between two DateTimeImmutable objects, and it returns a DateInterval object that represents the elapsed time between the two dates.

Here is an example of how to use the DateTimeImmutable and diff methods to calculate the elapsed time between two dates from datetime strings in PHP:

// Create two DateTimeImmutable objects from the datetime strings
$date1 = new DateTimeImmutable('2022-12-05 12:00:00');
$date2 = new DateTimeImmutable('2022-12-06 13:00:00');

// Calculate the elapsed time between the two dates
$elapsed = $date2->diff($date1);

// Output the elapsed time using the format method of the DateInterval object
echo $elapsed->format('%y years, %m months, %d days, %h hours, %i minutes, %s seconds');

This code will output the elapsed time between the two dates in the format Y years, M months, D days, H hours, I minutes, S seconds. You can adjust the format string to include only the parts of the elapsed time that you want to display.
