PHP Tutorials: Build Real Projects Step by Step
This page collects the hands-on PHP material in one place: tutorials that build something real from start to finish, task walkthroughs that get one job done, and two security references worth keeping open while you build. Every entry is a complete article, and this page is the map.
Where to Start
If you are new to PHP projects, build in this order: Build Dynamic Sites with PHP and MySQL first, because it teaches the request-to-database loop every other project reuses. Then the mini chat app for forms and polling, and Add Search to a PHP and MySQL App once you have data worth searching. Keep PHP Security Fundamentals open from the second project onward.
Shorter jobs are here too. Sending email from PHP or creating image thumbnails takes minutes rather than an afternoon, so pick one of those when you want a single thing working today.
Databases and MySQL
The core of the archive: applications built on a database, in the order the pieces were meant to be learned.
- Build Dynamic Sites with PHP and MySQL: the foundational request-query-render loop.
- PHP and MySQL with PDO: the modern database layer the other tutorials build on.
- Build a Mini Chat App with PHP: forms, inserts, and a polling refresh in one small app.
- Add News and Comments with PHP and MySQL: one-to-many data in a real page.
- Add Search to a PHP and MySQL App: LIKE queries, relevance, and result pages.
Forms and Validation
- PHP Email Validation: validating addresses server-side before anything is stored or sent.
- Form and Spelling Validation in PHP: checking user input beyond the format level.
Email, Messaging, and APIs
- Sending Email in PHP: text and HTML mail with attachments, done safely.
- Sending SMS with HTTP APIs: reaching phones from PHP through an HTTP gateway.
- Build a Custom API with PHP: exposing your own application's data as an API.
Images and Media
- Create Image Thumbnails with PHP: a directory thumbnail system with GD.
- Composite Images with PHP and GD: layering and overlapping images server-side.
- Streaming Media with PHP: serving audio through PHP rather than direct file links.
Files, Templates, and XML
- Working with Text Files in PHP: reading, writing, and appending safely.
- Writing a Template System in PHP: separating markup from logic by hand, which is what every template engine automates.
- Processing XML with PHP: parsing feeds and structured documents.
- Recursion in PHP: the technique behind directory walkers and tree menus.
Networking and the Browser
- Using Sockets in PHP: talking to other servers below the HTTP layer.
- Smart Auto Refresh with PHP: refreshing a page only when its data has changed.
Security References
Not tutorials, but the two pages to keep open while following any of the above.
- PHP Security Fundamentals: the attacks every PHP application faces and the habits that prevent them.
- PHP Authentication and Sessions: a reference for login systems and session handling.
Beyond the Tutorials
The PHP guide is the language's home page, and the Guides group in the sidebar covers the concept side: control flow, object-oriented PHP, configuration, the LAMP stack, and the framework landscape. When a tutorial's database side raises questions, the SQL section answers them properly.
