How the Web Works

Ever wondered what happens behind the scenes when you visit a website? In this video, we break down the fundamentals of how the web works, focusing on how PHP processes requests and responses on the server. You’ll learn about HTTP & HTTPS, how browsers communicate with web servers, and what happens when you enter a URL. We’ll also explore key HTTP concepts like request methods, headers, response codes, and more. Plus, we’ll walk through a live example using browser developer tools to see it all in action. By the end, you’ll have a clear understanding of how PHP fits into the bigger picture of web development! 🚀

Inheritance

Introduction & Overview

Welcome to PHP: The Pragmatic Way! In this video, we set the stage for an exciting journey into dynamic web development. 🌐

We’ll start by touring the project’s goals, showing you where we’re landing and what’s ahead. The rule is simple: all the PHP code is ours! We begin with static HTML pages and gradually convert them into dynamic applications. 💻

Along the way, we’ll cover:
• Extracting a layout to avoid repetition 🔄
• Refactoring into an MVC architecture 🏗️
• Building a “mini-framework” to streamline development ⚙️

You’ll also learn how this framework introduces powerful features like routing, sessions, databases, models, views, and controllers. 🛠️

We’ll stick to best practices throughout—focusing on clean, secure, and maintainable code that’s easy to use. By the end of this series, you’ll be ready to implement these principles in your own projects!

Prerequisites: Basic PHP and OOP knowledge are recommended to get the most out of this series. Ready to dive in? Let’s go! 🚀

Invalid Form Submissions

In this video, we tackle the next critical part of the form experience—handling invalid submissions with grace. When a user submits a form with missing or incorrect data, we want to redirect them back, repopulate the form, and show helpful error messages. 💡

Here’s what we build in version v19-redirect-with-errors:


- Define the ideal usage:
- session()->invalid($errors)->redirect_back();
- Then… we make it real! 💥
- Introduce invalid() and redirect_back() methods in the Session class
- Store transient $old and $errors values to survive the redirect and improve UX ✨
- Refactor Session::old() into a more flexible Session::flash() and flash_message() pattern 🔁
- Improve the old($key, $default) helper to escape HTML using htmlspecialchars() for security 🛡️
- Add a validation_message() helper to display specific errors next to form fields
- Update the review form:
- Loosen validation so comment is optional
- Add hidden rating input with default of 0
- Test with extreme values (e.g., rating=10, long name) to confirm validation is triggered
- Clean up temporary debug outputs (like var_dump()) and finalize the flow ✅


This update makes your app smarter, friendlier, and much more user-friendly when things go wrong. A polished user experience, even on failure? Now that’s pragmatic. 🚀

Logic, Conditionals & Branching

In this video from the PHP for Beginners series, we explore logic, conditionals, and branching—key concepts that control the flow of your PHP programs. You’ll learn how to use if, else, and switch statements to make decisions in your code, allowing your programs to respond dynamically to different conditions.

By the end of this lesson, you’ll have a strong understanding of conditional statements and how to apply them effectively in real-world scenarios.

🔹 Beginner-friendly explanations
🔹 Hands-on coding examples

🚀 Master PHP conditionals and take control of your code today!

Looping Through Arrays

Ready to do something with all those array items? In this episode, you’ll learn how to loop through arrays and apply logic to each value — one of the most common tasks in JavaScript!

🎯 What you’ll learn:
• The classic for loop — great for full control
• The cleaner, modern for…of loop
• The elegant and expressive .forEach() method
• A fun mini-challenge: Loop through numbers and log which are even 🔍

🎥 What you’ll see:
• Step-by-step demos of each loop type
• Code that transforms and filters array data
• A clear comparison so you know when and why to use each loop

By the end, you’ll be confidently cycling through arrays and writing logic that reacts to each item. 🧠✨

Loops

Loops are a fundamental part of programming, allowing you to execute code multiple times efficiently. In this video, part of the “PHP for Beginners” series, we break down the four main types of loops in PHP:

✅ foreach – Perfect for looping through arrays effortlessly.
✅ for – Ideal when you know exactly how many times you need to iterate.
✅ while – Runs as long as a condition is true, great for dynamic scenarios.
✅ do…while – Similar to while, but always runs at least once.

By the end of this tutorial, you’ll understand when and how to use each loop, with clear explanations and examples. Whether you’re new to PHP or need a refresher, this video will help you master loops in no time!

Mixing Markup & Code

It’s time to take our PHP calculator from hardcoded values to real user input! In this video we introduce an HTML frontend to drive our calculator, making it interactive.

Here’s what we cover:

✅ Creating an HTML form – Allow users to input expressions dynamically.
✅ PHP Superglobals – Understanding $_POST and how to handle form data.
✅ Mixing PHP & HTML – Embedding PHP inside markup to render values and conditionally show elements.

By the end of this tutorial, you’ll know how to build dynamic web pages that process user input using PHP—an essential skill for web development!

Namespaces, PSR-4, and Autoloading

Say goodbye to messy, single-file chaos! 😵‍💫 In this video, we organize and supercharge our PHP projects by breaking them into multiple files. First, we manually load classes using the trusty require keyword 📜—but that’s just the beginning!

Next, we introduce the PSR-4 standard, the industry gold standard for structuring PHP code 🏆. And to make life even sweeter, we harness the power of Composer’s autoloading ⚡—letting PHP automatically find and load classes like magic! ✨

By the end, you’ll be writing scalable, maintainable PHP code like a true OOP architect! 🏗️💻

Nested Structures & Loops w/Objects

As your programs grow more complex, you’ll often need to work with data inside of data. In this episode, we explore how to combine arrays and objects to model richer, more realistic structures.

🎯 What you’ll learn:
• How to create and work with arrays inside arrays (like a game board)
• How to structure objects inside objects (like a user and their account)
• How to manage arrays of objects (like a list of students)
• How to handle arrays inside objects (like student grades)

🎥 What you’ll see:
• Code examples of each structure
• How to access nested values
• How to loop through nested data using for loops or for...of

By the end of this episode, you’ll understand how to organize complex data and access it confidently — a big step toward working with real-world applications! 🗃️🔁

Objects - Key / Value Pairs

Objects are one of the most powerful and flexible tools in JavaScript. In this episode, we’ll explore how to represent real-world things — like people, places, or ideas — using key/value pairs.

🎯 What you’ll learn:
• What objects are and why they matter
• How to define and access object properties
• The difference between dot notation and bracket notation
• How to add, update, and delete properties dynamically

🎥 What you’ll see:
• A walkthrough of building a simple person object
• Real-time code edits and console logging
• Examples that mirror how data is structured in real apps

After this episode, you’ll see how objects give your data shape and make your code more expressive and organized. 🗂️📦
