When should a class be considered necessary in PHP development and when is it optional?

Classes in PHP should be considered necessary when you need to organize your code into reusable and structured components, especially for larger projects. Classes help in encapsulating data and functionality, promoting code reusability, and improving code maintainability. However, for smaller projects or simple scripts, classes may be optional and procedural programming can be sufficient. 

// Example of when a class is necessary
class User {
    private $name;
    
    public function __construct($name) {
        $this->name = $name;
    }
    
    public function getName() {
        return $this->name;
    }
}

$user = new User("John Doe");
echo $user->getName();

// Example of when a class is optional
$name = "Jane Smith";
echo "Hello, $name!";
