What are the advantages and disadvantages of using a class-based approach versus a function-based approach for password generation in PHP?

When generating passwords in PHP, using a class-based approach allows for better organization and encapsulation of code, making it easier to manage and reuse. On the other hand, a function-based approach may be simpler and more straightforward for smaller tasks. It ultimately depends on the complexity and scale of the password generation requirements.

// Class-based approach for password generation
class PasswordGenerator {
    public static function generatePassword($length = 8) {
        $characters = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ!@#$%^&*()-_=+';
        $password = '';
        $charLength = strlen($characters);
        
        for ($i = 0; $i < $length; $i++) {
            $password .= $characters[rand(0, $charLength - 1)];
        }
        
        return $password;
    }
}

// Example of using the class-based approach
$password = PasswordGenerator::generatePassword(12);
echo $password;
