How can PHP functions like mysql_set_charset() and mysqli_set_charset() be utilized to handle character encoding in database operations effectively?

When working with databases, it is important to ensure that the character encoding is properly set to avoid issues with special characters or language-specific characters. PHP functions like mysql_set_charset() and mysqli_set_charset() can be utilized to specify the character encoding for database operations. By using these functions, you can ensure that the data stored and retrieved from the database is in the correct character encoding, such as UTF-8.

// Using mysqli_set_charset() to handle character encoding in database operations
$mysqli = new mysqli("localhost", "username", "password", "database");

if ($mysqli->connect_error) {
    die("Connection failed: " . $mysqli->connect_error);
}

// Set character encoding to UTF-8
if (!$mysqli->set_charset("utf8")) {
    die("Error loading character set utf8: " . $mysqli->error);
}
