What are the implications of having different collations for the database and tables when updating MySQL databases in PHP?

Having different collations for the database and tables can lead to issues with data consistency and sorting when updating MySQL databases in PHP. To solve this issue, you can explicitly set the collation for the database connection in PHP using the "SET NAMES" query. 

// Establish a connection to the MySQL database with the correct collation
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database_name";

$conn = new mysqli($servername, $username, $password, $dbname);

// Set the collation for the connection
$conn->query("SET NAMES 'utf8'");

// Perform database operations here
