In what scenarios would using RAND() in an ORDER BY clause be appropriate in PHP MySQL queries?

Using RAND() in an ORDER BY clause can be appropriate when you want to retrieve rows in a random order. This can be useful for scenarios such as displaying random items on a website, shuffling the order of results in a quiz, or selecting a random winner from a list of participants. 

// Example PHP code snippet using RAND() in an ORDER BY clause
$query = "SELECT * FROM table_name ORDER BY RAND() LIMIT 10";
$result = mysqli_query($connection, $query);

if(mysqli_num_rows($result) > 0){
    while($row = mysqli_fetch_assoc($result)){
        // Output data from each row
    }
} else {
    echo "No results found";
}
