In what scenarios would it be advisable to store date and time values as integers in databases, and how can PHP effectively handle these conversions?

Storing date and time values as integers in databases can be useful when you need to optimize storage space or when you want to perform calculations or comparisons on the values. To effectively handle these conversions in PHP, you can use the `strtotime()` function to convert date and time strings to Unix timestamps, and the `date()` function to format timestamps as desired. 

// Convert a date string to a Unix timestamp
$dateString = '2022-01-01';
$timestamp = strtotime($dateString);

// Convert a Unix timestamp to a date string
$timestamp = 1640995200; // January 1, 2022
$dateString = date('Y-m-d', $timestamp);

echo $dateString; // Output: 2022-01-01
