How to Calculate and Format the Difference Between Two Datetimes as 'Y-m-d H:i:s'?

Calculating the Difference Between Two Datetimes in Y-m-d H:i:s Format

Determining the time difference between two datetimes is a common task in many programming scenarios. However, it's crucial to understand how to format the difference in a specific format.

In the given case, the user wants to find the difference between two datetimes and format it as "Y-m-d H:i:s". The provided code snippet uses the diff() method, but it's not formatted correctly.

To achieve the desired format, we can utilize the DateTime class. Here's an example:

$datetime1 = new DateTime();
$datetime2 = new DateTime('2011-01-03 17:13:00');
$interval = $datetime1->diff($datetime2);
$elapsed = $interval->format('%Y-%m-%d %H:%i:%s');
echo $elapsed;

In this example:

• $datetime1 and $datetime2 represent the initial and final datetimes.
• $interval calculates the difference between the two datetimes.
• $elapsed formats the difference in the desired "Y-m-d H:i:s" format.

By using this approach, you can obtain the difference between two datetimes and format it in the specified format.
