How can PHP version changes affect the functionality of date() function in time-dependent scripts?

PHP version changes can affect the functionality of the date() function in time-dependent scripts if the format strings used are not compatible with the new PHP version. To ensure compatibility and consistency across different PHP versions, it is recommended to use the DateTime class instead of the date() function. This class provides more flexibility and control over date and time manipulation.

// Using DateTime class to ensure compatibility with different PHP versions
$date = new DateTime();
echo $date->format('Y-m-d H:i:s');
