What considerations should be made when sorting data in a database versus sorting in PHP code?

When sorting data in a database, it is important to consider the performance impact, especially with large datasets. Sorting in the database can be more efficient as it utilizes indexes and optimized query execution plans. On the other hand, sorting in PHP code can be more flexible and customizable but may require fetching all data into memory, which can be resource-intensive. 

// Sorting data in a database
$query = "SELECT * FROM table_name ORDER BY column_name";
$result = mysqli_query($connection, $query);
while ($row = mysqli_fetch_assoc($result)) {
    // Process the sorted data
}

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