In what scenarios would it be more practical to handle date and time comparisons in PHP code rather than relying solely on SQL queries for time-sensitive data retrieval?

When dealing with time-sensitive data retrieval, it may be more practical to handle date and time comparisons in PHP code rather than relying solely on SQL queries. This is especially true when the time zone settings differ between the PHP application and the database server, or when complex date calculations are needed. By performing date and time comparisons in PHP, you have more control over the time zones and can easily manipulate dates and times using PHP's built-in functions.

// Example of handling date and time comparisons in PHP code

// Set the time zone for PHP
date_default_timezone_set('America/New_York');

// Get the current date and time in PHP
$currentDateTime = new DateTime();

// Perform date and time comparisons
$targetDateTime = new DateTime('2023-01-01 12:00:00');
if ($currentDateTime > $targetDateTime) {
    echo 'The target date and time has passed.';
} else {
    echo 'The target date and time is in the future.';
}
