How to calculate the difference in hours, minutes, and seconds between two DateTime objects in PHP?

To calculate the difference in hours, minutes, and seconds between two DateTime objects in PHP, you can follow these steps:

Create two DateTime objects representing your desired dates and times.
Use the diff() method to calculate the difference between these two DateTime objects. This method returns a DateInterval object.
Extract the hours, minutes, and seconds from the DateInterval object and store them in separate variables.

Here's an example code snippet demonstrating this process:

// Create two DateTime objects representing the desired dates and times
$datetime1 = new DateTime('2021-07-01 10:00:00');
$datetime2 = new DateTime('2021-07-02 14:30:30');

// Calculate the difference between the two DateTime objects
$interval = $datetime1->diff($datetime2);

// Extract the hours, minutes, and seconds from the DateInterval object
$hours = $interval->h;
$minutes = $interval->i;
$seconds = $interval->s;

// Print the difference
echo "Difference: {$hours} hours, {$minutes} minutes, {$seconds} seconds";

In this example, the difference between the two DateTime objects is calculated using the diff() method. The hours, minutes, and seconds are then extracted from the resulting DateInterval object using the h, i, and s properties, respectively. The final result is printed, displaying the calculated difference in hours, minutes, and seconds.
