What are the advantages and disadvantages of sorting arrays in PHP using SQL queries versus manipulating arrays directly in code?

When sorting arrays in PHP, using SQL queries can be advantageous as it allows for efficient sorting based on specific criteria using the database's built-in sorting capabilities. However, this approach may introduce additional complexity and overhead, especially if the data needs to be fetched from the database solely for sorting purposes. On the other hand, manipulating arrays directly in code provides more flexibility and control over the sorting process but may require more code to implement custom sorting algorithms. 

// Sorting an array using SQL query
$connection = new PDO("mysql:host=localhost;dbname=database", "username", "password");
$query = "SELECT * FROM table ORDER BY column ASC";
$statement = $connection->prepare($query);
$statement->execute();
$sortedArray = $statement->fetchAll(PDO::FETCH_ASSOC);

// Sorting an array directly in code
$array = [3, 1, 2, 5, 4];
asort($array);
