What is the recommended approach for selecting a random winner from a MySQL table using PHP?

When selecting a random winner from a MySQL table using PHP, one approach is to retrieve all the rows from the table, count the total number of rows, generate a random number within that range, and then fetch the row corresponding to that random number. 

// Connect to MySQL database
$connection = mysqli_connect("localhost", "username", "password", "database");

// Query to select all rows from the table
$query = "SELECT * FROM table_name";
$result = mysqli_query($connection, $query);

// Count the total number of rows
$total_rows = mysqli_num_rows($result);

// Generate a random number within the range of total rows
$random_number = rand(1, $total_rows);

// Query to fetch the row corresponding to the random number
$query_random = "SELECT * FROM table_name LIMIT " . ($random_number - 1) . ", 1";
$result_random = mysqli_query($connection, $query_random);

// Fetch the random winner from the result
$random_winner = mysqli_fetch_assoc($result_random);

// Display the random winner
echo "Random Winner: " . $random_winner['column_name'];

// Close the database connection
mysqli_close($connection);
