How to Calculate and Format Datetime Differences in Y-m-d H:i:s?

Calculating Datetime Differences and Formatting Results in Y-m-d H:i:s

When attempting to determine the difference between two datetimes and format the result in Y-m-d H:i:s, individuals may encounter issues similar to the one presented. The goal is to compute the time difference and store it in a datetime variable.

One approach involves utilizing the DateTime class:

$datetime1 = new DateTime();
$datetime2 = new DateTime('2011-01-03 17:13:00');
$interval = $datetime1->diff($datetime2);
$elapsed = $interval->format('%y years %m months %a days %h hours %i minutes %s seconds');
echo $elapsed;

In this example:

• $datetime1 and $datetime2 represent the two datetimes being compared.
• $interval calculates the difference between $datetime1 and $datetime2.
• $format defines the desired output format.
• $elapsed stores the formatted time difference.

The format method allows you to customize the output. In this case, '%y years %m months %a days %h hours %i minutes %s seconds' provides a detailed breakdown of the difference.

Using this approach, you can obtain the time difference between two datetimes and format it in the desired format.
