How to Calculate the Difference Between Two Dates Using PHP

In this blog post, we’ll explore how to calculate the difference between two dates using PHP. We’ll go through step-by-step instructions with code samples and comments to guide you through the process. By the end of this post, you’ll be able to calculate the difference between two dates easily using PHP.

Step 1: Create two DateTime objects

The first step is to create two DateTime objects for the dates you want to calculate the difference between. You can create DateTime objects by instantiating the DateTime class with the date string as an argument. Here’s an example:

<?php
# PHP
$date1 = new DateTime('2020-01-01');
$date2 = new DateTime('2023-04-21');
?>

Step 2: Calculate the difference between the two DateTime objects

Next, we’ll calculate the difference between the two DateTime objects using the diff() method. The diff() method returns a DateInterval object representing the difference between the two dates.

<?php
# PHP
$interval = $date1->diff($date2);
?>

Step 3: Display the difference

Now that we have the DateInterval object, we can display the difference between the two dates in various formats, such as years, months, days, etc. To do this, we can access the properties of the DateInterval object. Here’s an example of how to display the difference in years, months, and days:

<?php
# PHP
echo "Difference: " . $interval->y . " years, " . $interval->m . " months, " . $interval->d . " days";
?>

Complete Example:

Here’s the complete example, which calculates the difference between two dates and displays it in years, months, and days:

<?php
# PHP
$date1 = new DateTime('2020-01-01');
$date2 = new DateTime('2023-04-21');
$interval = $date1->diff($date2);
echo "Difference: " . $interval->y . " years, " . $interval->m . " months, " . $interval->d . " days";
?>

Conclusion:

In this blog post, we’ve learned how to calculate the difference between two dates using PHP. By creating two DateTime objects, calculating the difference using the diff() method, and displaying the result, you can easily find the difference between any two dates. Happy coding!
