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

When deciding whether to sort data in PHP arrays or directly in SQL queries, it's important to consider factors such as performance, scalability, and maintainability. Sorting data in SQL queries can be more efficient for large datasets since the database engine can leverage indexes and optimized algorithms. However, sorting in PHP arrays can provide more flexibility and control over the sorting logic, especially when dealing with complex sorting requirements. 

// Sorting data directly in SQL query
$sql = "SELECT * FROM table_name ORDER BY column_name ASC";
$result = $conn->query($sql);
while($row = $result->fetch_assoc()) {
    // Process sorted data
}

// Sorting data in PHP array
$data = array(/* data from database */);
usort($data, function($a, $b) {
    return $a['column_name'] <=> $b['column_name'];
});
foreach($data as $row) {
    // Process sorted data
}
