How Can I Calculate and Format the Time Difference Between Two DateTime Objects in PHP?

Calculate and Format Time Difference between DateTimes

When working with date and time values, it becomes necessary to calculate the difference between two specific points in time. This can be a common task when tracking elapsed time or performing time-based calculations.

To achieve this, one of the approaches commonly used is the diff() method provided by the DateTime class. This method allows you to determine the difference between two DateTime objects and obtain the time span as a DateInterval object.

However, it's important to note that the diff() method does not return a formatted version of the time difference. To display the result in a specific format, you need to use the format() method of the resulting DateInterval object.

Here's an example of how you can calculate and format the time difference between two datetimes:

In this example, the difference between $datetime1 and $datetime2 is calculated and formatted as "0 years 0 months 0 days 2 hours 30 minutes 0 seconds". The format() method allows you to specify the desired format for the time span, and the placeholder codes will be replaced with the corresponding values.
