What are some best practices for sorting data in PHP when the value used for sorting is not directly available in the database?

When the value used for sorting is not directly available in the database, one approach is to retrieve the data and store it in an array in PHP. Then, use PHP functions like `usort()` to sort the array based on the desired value. Finally, display the sorted data on the webpage. 

// Retrieve data from the database
$data = fetchDataFromDatabase();

// Define a custom sorting function based on a specific value
usort($data, function($a, $b) {
    return $a['valueToSortBy'] <=> $b['valueToSortBy'];
});

// Display the sorted data
foreach ($data as $item) {
    echo $item['name'] . ' - ' . $item['valueToSortBy'] . '<br>';
}
