What are the potential limitations of capturing and displaying dynamic data, such as time calculations, in different sections of a PHP website?

When capturing and displaying dynamic data like time calculations in different sections of a PHP website, a potential limitation is the need to ensure consistency and accuracy across all sections. To address this, it's important to centralize the calculation logic in a separate function or class to avoid duplicating code and risking inconsistencies. By creating a reusable function for time calculations, you can easily call it in different sections of the website to display accurate and consistent results.

<?php

function calculateTimeDifference($startTime, $endTime) {
    $start = new DateTime($startTime);
    $end = new DateTime($endTime);
    $interval = $start->diff($end);
    
    return $interval->format('%H hours %i minutes');
}

// Example of calculating time difference and displaying it
$startTime = '2022-01-01 09:00:00';
$endTime = '2022-01-01 13:30:00';

$timeDifference = calculateTimeDifference($startTime, $endTime);
echo "Time difference: " . $timeDifference;

?>
