In the context of PHP and MySQL, what are some alternative approaches to selecting a random record from a database table for banner display?

When selecting a random record from a database table for banner display in PHP and MySQL, one approach is to use the RAND() function in the SQL query to fetch a random row. Another approach is to retrieve all the records and then select a random one using PHP array functions. Both methods can be effective, but using the RAND() function in the SQL query is generally more efficient.

// Using RAND() function in SQL query
$query = "SELECT * FROM banners ORDER BY RAND() LIMIT 1";
$result = mysqli_query($connection, $query);
$row = mysqli_fetch_assoc($result);
echo $row['banner_image'];

// Using PHP array functions
$query = "SELECT * FROM banners";
$result = mysqli_query($connection, $query);
$rows = [];
while ($row = mysqli_fetch_assoc($result)) {
    $rows[] = $row;
}
$randomRow = $rows[array_rand($rows)];
echo $randomRow['banner_image'];
