How can PHP developers ensure the accuracy of sorted results when dealing with multiple criteria in MySQL queries?

When dealing with multiple criteria in MySQL queries, PHP developers can ensure the accuracy of sorted results by specifying the order of the criteria in the SQL query. By defining the order of the criteria in the ORDER BY clause, developers can control how the results are sorted and ensure that the sorting is done accurately. 

// Example of sorting results by multiple criteria in a MySQL query
$sql = "SELECT * FROM table_name ORDER BY column1 ASC, column2 DESC";
$result = mysqli_query($conn, $sql);

if (mysqli_num_rows($result) > 0) {
    while ($row = mysqli_fetch_assoc($result)) {
        // Process each row as needed
    }
} else {
    echo "0 results";
}
