PHP is a popular general-purpose scripting language that is especially suited to web development.

Fast, flexible and pragmatic, PHP powers everything from your blog to the most popular websites in the world.

Using "require" for classes isn't a modern practice for PHP development. A much better option is to use Composer's autoloader to automatically import classes into your app.

Replace PHP require statements with the Composer class autoloader

Once you start creating PHP classes, you'll want to organize them into groups of classes. In this lesson, you'll learn how to do just that with namespaces.

Defining & using PHP namespaces

Creating functions around your app is just fine, but when your app grows in complexity, you will want to create those functions as being part of PHP classes. This will help your app scale & expand with time.

Refactoring functions into PHP classes

Class properties and methods can have different visibility levels, which control how private or protected those properties are.

Understanding scope in PHP classes

Creating class properties is useless unless you can read back that property! There's an easy way to do this, with PHP's shorthand arrow syntax.

Retrieve public class properties with PHP’s arrow syntax

There's a new way to create class properties in PHP 8. In this lesson, you'll learn about "promoted properties", also referred to as "constructor property promotion".

Create promoted properties in PHP 8 classes

Attaching properties to a PHP class is important, so you can track specific values of data entities or functionality.

Create class properties in previous versions of PHP

It's very common to execute a piece of code when an object is created. In this lesson, you'll learn how to do just this with a PHP class constructor.

Run code on PHP class creation with a constructor

Creating a class in PHP is quite easy with the "new" keyword, and can represent a specific data entity or functionality.

Create & instantiate a class in PHP

Files can get hard to read & debug if they get too long. In this lesson, we'll learn how to include external files in your PHP scripts.

Including or requiring files in PHP

PHP "juggles" data types with something called "type coercion". Let's learn all about that!

Type coercion & strict data types in PHP

Types are important in any programming language. In PHP, you can define argument & return types to build more reliable applications.

Defining function return & argument types in PHP

You can't get data into a function without arguments. In this lesson, we'll learn how to pass variables as arguments to PHP functions.

Passing arguments to PHP functions

A PHP function can encapsulate a block of code, but it can also return values. In this lesson, we will learn how to return values created within a function.

Calling functions with return values in PHP

Scope in PHP is how variables are encapsulated in pieces of code. Let's learn about function & global scope in PHP.

Function & global scope in PHP

In this lesson, we will go over how to create a function with proper syntax in PHP with the function keyword.

Create a function in PHP

Sometimes you need to group together pieces of code. That's what functions are for! In this lesson, we'll learn all about them.

Purpose of a function in PHP

Sometimes you need to escape out of a PHP loop. You can easily do this by using either the continue or break keywords.

Continue or break out of a PHP loop

Different from a foreach loop, a for loop in PHP allows you to iterate through an array based on an index or another conditional value.

Display the contents of an array with a for loop

There are many functions available relating to PHP arrays, and one of them is count, to get the total number of elements within an array.

Get the count of a PHP array

Storing an array within an array is possible with PHP, and are called "multi-dimensional" arrays.

Create a nested or multi-dimensional array in PHP


Using Cursor Chat, you can easily reference an entire directory of files and ask it to generate anything based on those files. This opens up the possibility of using your current code as a reference guide to create new code that follows existing patterns. With this approach, the result can be a polished prompt you can use with any AI to generate consistent and reliable output.

Focus less on crafting the perfect prompt upfront - what matters most is testing and iterating based on the AI's responses. The more results you see from the prompt, the more you can reinforce the good results and prune out the bad results until your prompt is polished enough that you can rely on the prompt to give you consistent quality results.


Create AI Prompts Based on a Directory of Files


With Cursor's "Composer" feature, you can select and entire directory and make changes to every file. This video walks through the process of selecting a folder and refactoring all the files from JavaScript to TypeScript. It also demonstrates other tips around generating terminal commands and customizing your main Cursor "Rules for AI".

This lesson breaks down the concept of asynchronous iterators and generators in JavaScript. Using the Node.js glob function as a practical example, you'll learn how Array.fromAsync facilitates the creation of arrays from asynchronous iterables and how generators can improve performance in file processing tasks.

With the introduction of Svelte 5, the Svelte team has created a CLI, `sv`, that unifies all the tasks that previously spread across a handful of CLIS (create, add plugins, and migrate).

This lesson will create a Svelte project using the new `sv` CLI and build a counter component to showcase the new `$state`, `$derived`, and `$effect` runes that ship with the new version.



Get Started with Svelte 5 using the sv CLI

You'll create a SvelteKit project using the sv CLI and build a counter component showcasing Svelte $state, $derived, and $effect runes.



pnpm ships with a streamlined, easy way of managing Node.js versions for youself and your team. This video demonstrates why pnpm uses a specific version of Node.js, how to configure it globally, and how to set up your project so that anyone who is running your project will automatically use the same version of Node.js even if that version of Node.js is not installed.

How you build with Angular has changed quite a lot over the years.

For example, the `inject` function was introduced in version 14 but you might still be familiar with Angular's constructor injection.

Similarly, structural directives like `ngif` or `ngfor` have been replaced with `@if` and `@for` blocks since version 17 and beyond.

These are patterns that need to be adjusted if you want to stay up-to-date with the latest Angular has to provide.

Luckily, Angular gives you great tools in the form of a migration CLI for supporting your migration efforts as you incrementally update your App from older version features and patterns. 

When you're done with this course you'll know how to target specific features, folders, and files to migrate to the latest Angular version.

You'll learn how to 'migrate':
- Structural directives with control flow syntax
- Constructor dependency inject to inject function
- Make components standalone
- Lazy load routes
- Input/Output decorators to signal-based API


Angular Migrations in Practice

Migrate old Angular patterns for version 18 and beyond

When we import assets in React components outside of the `public` folder that Nitro reads for assets by default when running the development server we need to tell Nitro how to find them with the `devProxy` configuration option.

```typescript
export default defineNitroConfig({
  renderer: './renderer.ts',
  devProxy: {
    '/app/assets': 'http://localhost:5173/app/assets'
  }
})
```

This is ultimately inadequate in scenarios where you want to import assets arbitrarily and have them "just work" but works in a pinch.



Use devProxy in Nitro Config to Serve Static Imported Assets in Dev Mode via Vite

Learn how to use devProxy in Nitro Config with Vite to serve static assets in React components in dev mode.

Start with a basic Vite React TypeScript app and enhance it for production use by integrating Nitro as the server. 

This requires a custom Vite plugin for nitro as well as a custom renderer and manually creating Nitro config.

The other way to approach this would be to add Vite to a Nitro app instead. Same basic result.

The [Nitro config reference](https://nitro.unjs.io/config) is a great read of you'd like to explore more options.

Over the years, your application have grown huge. Sometimes, really HUGE.

Many developers have contributed to the codebase. One day they pushed one coding style, a different one another day. Sometimes even different patterns and solutions for similar problems.

You want to keep your codebase consistent. In the Angular ecosystem, there were well established patterns for doing things the right way ™️. But the old solutions are being challenged by signal-based approach.

Eventually, you ask yourself the key question: **Should you integrate with the NEW solutions or stick to the battle-tested ones, but already considered LEGACY**?

That's a very good question indeed. Don't rush with architectural decisions 🤓.

## First, think of what problems you want to solve by introducing the change.

Do you have 1k LoC Angular components? Maybe even 2k? Do you and your team enjoy working with these? 😏

Where does the **domain logic and state management code** belong to - do you have a clear guidance on which code should be put where? Have you spot that different devs implement similar features in totally different ways?

Do you keep on asking the same questions over and over again: **whether this certain piece of code** should be **imperative** (plain old object properties and variables) or **reactive** (streams)? It'd be nice to keep all thinga reactive, but more often than not, it introduces complexity.

## Second, think of long-term consequences.

You are going to have more than one way to **manage the state**. But is that really an issue? If your codebase is modular, separate modules should not depend on each other in any way. Inner abstractions of one should be invisible to the other, etc.

You are going to introduce a **new tool**. On one hand, you need to learn it, and so does your team. But on the other hand, it's a breathe of fresh air. And it's useful to question the way you've been doing things so far. Maybe there's a more effective way?

You are going to embrace signal-based APIs. And that means taking taking advantage of Zoneless Angular. This means using all modern Angular APIs. And you know that signals are the future. Why would you want to stick to the **less performant, less type-safe, less flexible and, objectively, less effective solutions**?

## Finally, plan your INCREMENTAL integration.

INCREMENTAL is the absolute keyword here. You don't want to tell your PM you need to stop delivering features because of a refactor.

Actually, there's no need for a "refactor". Just pick the first new feature to be implemented. Or pick the one that needs to be extended.

NGRX Signal Store allows you to create both very simple & small stores, as well as bigger ones. **Composition** is the key here.

**Start simple**.

Create a `withState` section with the signals that hold the state. That's already reactive. And relatively simple.

```ts
const initialState: CartState = {
  items: ...,
  rebate: ...,
}

export const CartStore = signalStore(
  withState(initialState)
);
```

Create a `withMethods` section to provide ways to change the state:

```ts
export const CartStore = signalStore(
  ...
  withMethods((store) => ({
    addItem(item: ShoppingItem): void {
      patchState(store, (state) => ({ items: [ ...state.items, item ] }));
    },
    ...
);
```

Create a `withComputed` section to provide all derived computations:

```ts
export const CartStore = signalStore(
  ...
  withComputed(({ items }) => ({
    totalPrice: computed(() => items().reduce(...))
    ...
);
```

**Start simple**.

Now you can (literally) **`inject` this code into your existing solution**. All you need is to inject your brand new NGRX Signal Store implementation into a component, or a service:

```ts
@Injectable()
class ExistingBigService {
  cartStore = inject(CartStore)
  //...  
}
```

and that's it! What's beatiful is that NGRX Signal Store should remain an implementation details (of a component, service, etc). It **shouldn't leak outside to the entire application unintentionally**. Small NGRX Signal Stores help us to **keep logic more modular**.

Don't hesitate - give NGRX Signal Store a try! Start with the [_**Scalable Signals Angular Architecture with NGRX Signal Store**_](https://egghead.io/courses/scalable-signals-angular-architecture-with-ngrx-signal-store-a33abd39) course now!
