To design a proxy pattern in Laravel, you can follow these steps:

  1. Create an interface that defines the operations that the proxy and the real subject (the object being proxied) will implement. This interface will define the contract for the proxy and the subject to adhere to.

// ProxySubject interface
namespace AppPatterns;

interface ProxySubject {
    public function operation(): void;
}


  1. Create a class that implements the interface and acts as the real subject that the proxy will be proxying. This class will perform the actual operations.

// RealSubject class implementing the ProxySubject interface
namespace AppPatterns;

class RealSubject implements ProxySubject {
    public function operation(): void {
        // Perform some operation
    }
}


  1. Create a proxy class that also implements the interface. This proxy class will control access to the real subject and may perform additional tasks before or after delegating to the real subject.

// Proxy class implementing the ProxySubject interface
namespace AppPatterns;

class Proxy implements ProxySubject {
    protected $realSubject;

    public function __construct(RealSubject $realSubject) {
        $this->realSubject = $realSubject;
    }

    public function operation(): void {
        // Perform some additional tasks before delegating to the real subject
        $this->realSubject->operation();
        // Perform some additional tasks after delegating to the real subject
    }
}


  1. Use the proxy class in your application by creating an instance of the real subject and wrapping it with the proxy class.

// Using the Proxy pattern in your Laravel application
$realSubject = new RealSubject();
$proxy = new Proxy($realSubject);

// Call the operation method through the proxy
$proxy->operation();


By following these steps, you can design and implement a proxy pattern in your Laravel application.
