What are the advantages of sorting data directly in the database query versus sorting it in PHP after retrieval?

Sorting data directly in the database query is more efficient because it reduces the amount of data that needs to be transferred from the database to PHP. This can lead to faster processing times and lower memory usage. Additionally, sorting in the database allows for the use of indexes, which can further improve performance. On the other hand, sorting data in PHP after retrieval may be more flexible and easier to implement for complex sorting requirements. 

// Sorting data directly in the database query
$query = "SELECT * FROM table_name ORDER BY column_name";
$result = mysqli_query($connection, $query);

// Fetching and displaying sorted data
while ($row = mysqli_fetch_assoc($result)) {
    echo $row['column_name'] . "<br>";
}
