What are some common mistakes that beginners make when trying to implement dynamic navigation using PHP and how can they be addressed?

One common mistake beginners make when implementing dynamic navigation using PHP is not properly setting up their database queries to fetch the navigation items. To address this, make sure to establish a connection to your database and execute a query to retrieve the navigation items. 

// Establish a connection to the database
$connection = new mysqli('localhost', 'username', 'password', 'database_name');

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

// Execute a query to fetch navigation items
$query = "SELECT * FROM navigation_items";
$result = $connection->query($query);

// Loop through the results and display navigation items
while ($row = $result->fetch_assoc()) {
    echo '<a href="' . $row['url'] . '">' . $row['title'] . '</a>';
}

// Close the connection
$connection->close();
