How can PHP developers avoid the need to constantly decode and encode UTF-8 data when interacting with a MySQL database?

PHP developers can avoid the need to constantly decode and encode UTF-8 data by setting the character set to UTF-8 in the database connection and using prepared statements when interacting with the MySQL database. This ensures that data is stored and retrieved in UTF-8 format without the need for manual encoding and decoding.

// Establish a connection to the MySQL database with UTF-8 character set
$mysqli = new mysqli("localhost", "username", "password", "database");
$mysqli->set_charset("utf8");

// Prepare a statement with UTF-8 data
$stmt = $mysqli->prepare("INSERT INTO table_name (column_name) VALUES (?)");
$stmt->bind_param("s", $utf8_data);

// Execute the statement with UTF-8 data
$utf8_data = "UTF-8 encoded data";
$stmt->execute();
