What is the best practice for structuring SQL queries in PHP functions for updating database records?

When structuring SQL queries in PHP functions for updating database records, it is best practice to use prepared statements to prevent SQL injection attacks and improve performance. Prepared statements allow you to separate the SQL query from the data being passed in, making it more secure and efficient. Below is an example of how to structure a PHP function for updating database records using prepared statements: 

function updateRecord($conn, $id, $newData) {
    $stmt = $conn->prepare("UPDATE table_name SET column1 = ?, column2 = ? WHERE id = ?");
    $stmt->bind_param("ssi", $newData['column1'], $newData['column2'], $id);
    $stmt->execute();
    $stmt->close();
}
