What is the significance of using SET NAMES in MySQL queries and how does it relate to database selection in PHP?

When working with MySQL databases in PHP, it is important to set the character set for the connection using the SET NAMES query. This ensures that data is stored and retrieved correctly, especially when dealing with special characters or different languages. By setting the character set at the beginning of the connection, you can avoid potential encoding issues in your database operations. 

// Establish database connection
$connection = mysqli_connect("localhost", "username", "password", "database");

// Set character set for the connection
mysqli_query($connection, "SET NAMES 'utf8'");

// Now you can perform your database queries
$query = "SELECT * FROM table_name";
$result = mysqli_query($connection, $query);

// Process the query results
// ...

// Close the connection
mysqli_close($connection);
