In the context of PHP and MySQL, what are the potential pitfalls of assuming default database connection settings, as seen in the example provided in the forum thread?

Assuming default database connection settings can lead to security vulnerabilities, such as using default usernames and passwords that are easily guessed or known. To solve this issue, it is important to always customize and secure your database connection settings by using strong passwords, unique usernames, and restricting access to specific IP addresses. 

// Specify custom database connection settings
$servername = "localhost";
$username = "myusername";
$password = "mypassword";
$database = "mydatabase";

// Create connection
$conn = new mysqli($servername, $username, $password, $database);

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