What are the potential pitfalls of using both mysqli and PDO connections in parallel in a PHP project?

Using both mysqli and PDO connections in parallel in a PHP project can lead to confusion and inconsistency in database interactions. It is recommended to stick to one type of database connection throughout the project to maintain code readability and consistency. 

// Example of using only PDO connection in a PHP project
try {
    $pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch (PDOException $e) {
    die("Error connecting to database: " . $e->getMessage());
}
