How can you separate classes and frameworks for easier deployment and testing locally?

To separate classes and frameworks for easier deployment and testing locally, you can organize your project structure by placing classes in a separate directory from the frameworks. This way, you can easily manage and test your classes independently of the frameworks. You can also use namespaces to organize your classes and autoload them using Composer to simplify the dependency management.

// Example project structure:
// /app
//    /classes
//        MyClass.php
//    /framework
//        /vendor
//            autoload.php
//    index.php

// Composer autoload
require_once 'framework/vendor/autoload.php';

// Autoload classes using namespaces
spl_autoload_register(function ($className) {
    $file = str_replace('\\', '/', $className) . '.php';
    require_once 'app/classes/' . $file;
});

// Example class
namespace MyApp\Classes;

class MyClass {
    public function __construct() {
        echo 'MyClass instantiated';
    }
}

// Instantiate class
$myClass = new \MyApp\Classes\MyClass();
