What are the advantages and disadvantages of using a hobby coder versus a professional for PHP website development?

Using a hobby coder for PHP website development can be cost-effective and may result in a more personalized touch to the project. However, hobby coders may lack the experience and expertise of a professional, leading to potential issues with code quality, security vulnerabilities, and scalability.

// Example PHP code snippet for implementing a fix using a professional developer

// Define a class for handling user authentication
class UserAuthentication {
    public function login($username, $password) {
        // Implement secure login logic here
    }

    public function logout() {
        // Implement secure logout logic here
    }
}

// Instantiate the UserAuthentication class and use its methods for user authentication
$userAuth = new UserAuthentication();
$userAuth->login($username, $password);
$userAuth->logout();
