Become a PHP API Pro: Learn the Essentials of API Development in PHP!
Unleash powerful, scalable APIs 🔥
"Zero confusion...only crystal clear understanding of API concepts and their practical application." Gary
Essential Learning for Every PHP Developer
Every PHP developer will eventually be required to build and maintain APIs—that’s a fact of life for us all. However, with so many considerations and different approaches, it can be hard to know if you're doing it right.
It’s easy to feel overwhelmed with all the terminology and conflicting advice. How do you know who to believe? What are you supposed to know? Is there a ‘best way’ to version, secure, and optimize an API, or does it all depend?
That level of understanding and experience might seem years away from where you are now… Am I right? Actually, I’m wrong! You’re a lot closer than you think.
I’ve packaged everything you need to know into a coherent video course that is relevant to you, easy to understand, and painless to apply.
Starting from scratch, we’ll build our own API. I’ll take all the jargon and confusing concepts, explain them in plain language, demonstrate them using logical, practical examples, and let you try parts that will embed this knowledge into your brain.
Every PHP position requires API knowledge. I’ll give you the edge over the competition by showing you not just how to do things, but when, where, and why to apply certain techniques, and how those can differ in various scenarios.
While many developers have an average understanding of APIs, HTTP, and web development, by the time you finish this course, you'll be the expert in the room.

Course Introduction - How REST Works
This video will show you all of the main components of REST, why they exist, and how they are used.
What are Resource Identifiers?
A Resource Identifier, also known as a URI (Uniform Resource Identifier), is an essential component of RESTful APIs as it allows clients to interact with specific resources by targeting their unique identifiers.
Using Postman
When it comes to testing an API, using a web browser can have its limitations. This is where tools like Postman come in handy. Postman is a popular API development and testing tool that allows you to easily make requests to APIs.
Idempotency
Idempotence means that the result of performing an operation multiple times is the same as performing it once. It is important that your API behaves in expected ways and knowing which operations should / should not be idempotent will help you with this.
PUT Operations
A HTTP PUT operation is used to update or replace a resource on the server. When you send a PUT request to a specific URI, you're instructing the server to update the resource at that location with the new data provided in the request body.
Create an OAS using the Swagger Editor
The Open API Specification looks scary on first glance but actually there are tools we can use which makes the experience of creating one really quite painless...almost enjoyable!
Creating Nested Resources
A reservation can't exist without a related flight so it kinda makes sense to create this as a nested resource on a flights endpoint. Let me show you what I mean.
Paginating a Query
Here I'll show you how you can edit a database query so that it can also handle pagination.
HTTP Cache Middleware
We can create A Http Cache Middleware and add it only to the routes where we want Http Caching to apply.
URI Versioning
URI versioning, where the version number is included directly in the URI (Uniform Resource Identifier) of an API, is one of the most common methods for managing API versions.
The Postman CLI
The Postman CLI tool is an advanced command-line interface that allows API developers to run their Postman collections directly from the terminal.

Also check out these high-quality LIVE STREAMS which I created to accompany the course!
More to come! Make sure you subscribe for my live schedule!
Live Dive into RESTful Resources
This is the first live coding session to accompany the PHP API Pro course. In the session I'll create routes and handlers for retrieving single flights and collections of flights from the API. We'll also consider what our response content (representation) should look like when we serialize it as well as discussing other things.
Content Negotiation using Middleware and Enums
This is the second live coding session to accompany the PHP API Pro. In this session I'll create PSR15 middleware which leans on enums to handle content negotiation by checking the request accept header in order to serve content in the requested format. I'll also show you a really cool refactoring hack 😉
REST API basics with the API Guy JustSteveKing
This is the third live session to accompany the PHP API Pro course. Join us live as we delve deep into the world of RESTful APIs with the expertise of API guru JustSteveKing. Whether you're a seasoned developer or just starting out, this stream is the perfect opportunity to enhance your understanding of REST operations, their purposes, status codes, representations, and much more.
OpenAPI 3: Design REST API using Swagger Editor.
In this fourth live session to accompany the PHP API Pro course I will show you how to create an OpenAPI document using the Swagger editor. I'll discuss the benefits of Open API and also talk you through the differences between code-first, design-first, and api-first approaches to API development.
PHP API Pro: Live Dive into REST error handling
This is the fifth live coding session to accompany the PHP API Pro course. In this session I'll create a custom validation exception and use a ProblemDetail enum in order to format a 422 unprocessable content error response which contains details of the errors plus hypermedia which allows the client to research the problem further.
PHP API Pro Live - API Pagination and Hypermedia
This is the sixth live coding session to accompany the PHP API Pro course. In this session I'll dynamically generate API hypermedia, including pagination page and metadata links. Then I'll refactor this away into a reusable factory class which can be used to paginate any collection resource 💪

Hello and thank you so much for checking out my work. My name is Gary Clarke and I'm a software developer with many years experience, primarily in PHP. I started creating video tutorials during lockdown in 2020 because I wanted the challenge of being able to explain complex / technical subjects to others in a way which is easy to understand and remember.
At this moment in time, my videos have been watched over half a million times and I intend to keep creating new and improved content and teaching more and more new people. It would be my pleasure to see you on the inside of one of my courses.
