Calculate the Duration Between Two Time Strings in PHP Using DateTime

Calculating the duration between two time strings is a common requirement in many applications, and PHP provides a straightforward way to achieve this using the DateTime class and the diff method. Whether you're working on logging events, scheduling tasks, or any other time-based functionality, understanding how to calculate the duration between two times can be extremely beneficial.

How to Use DateTime and diff in PHP

PHP's DateTime class, in conjunction with the diff method, allows you to compute the difference between two dates or times effortlessly. Here is a step-by-step guide on how to achieve this.

Step 1: Create DateTime Objects

First, you need to create DateTime objects for the two time strings you want to compare. Assume we have the following time strings:

The $interval object now contains the difference between the two times.

Step 3: Output the Result

The interval object provides various properties like y (years), m (months), d (days), h (hours), i (minutes), and s (seconds) to access the difference. You can format the output as needed:
