Course Overview
Front-end code decides what a page looks like. Back-end code decides what is true. The moment a site needs a login, an order, a stock count or a booking, someone has to write the half that remembers things — and that half is where the security bugs live.
This course teaches that half. PHP because it is on almost every shared host in India and you can put something live the week you learn it; MySQL because storing data properly is the skill that transfers to every other database you will ever use. Twelve chapters, one application built through all of them.
No back-end experience assumed. Some HTML helps.
What You’ll Learn
✅ How a request works: what happens between a form submit and a page coming back.
✅ PHP: syntax, functions, arrays, includes, and writing code you can still read next month.
✅ Forms and state: $_POST, validation, sessions, cookies, logins.
✅ MySQL: designing tables, relationships, and writing queries that answer real questions.
✅ Security as a habit: prepared statements, password hashing, output escaping — taught with the feature, not bolted on.
✅ Performance: indexes, and what an index costs you.
The Chapters
1 — What the server does. Request, response, where PHP runs and why the visitor never sees it. You can explain what is different about code that runs on a server.
2 — PHP basics. Variables, types, operators, output, and the local environment. You can run a PHP file and print something computed.
3 — Control and functions. Conditions, loops, functions, === versus ==. You can write a function used in three places instead of three copies of the same lines.
4 — Arrays and includes. Indexed and associative arrays, require versus include, a shared header and footer. You can build a multi-page site with one copy of the layout.
5 — Forms. $_GET, $_POST, validating what arrived, re-displaying it safely. You can accept a form submission and never trust it.
6 — Databases, thinking first. Tables, rows, columns, keys, and what belongs in which table. You can design a schema for a real thing without repeating data.
7 — SQL. SELECT, INSERT, UPDATE, DELETE, WHERE, ORDER BY, LIMIT. You can get exactly the rows you want, and no others.
8 — PHP and MySQL together. Connecting, prepared statements, bound parameters, reading results. You can build a full create-read-update-delete screen that is injection-proof by construction.
9 — Relationships and joins. Foreign keys, JOIN and LEFT JOIN, GROUP BY and HAVING. You can answer "which customers have never ordered" in one query.
10 — Sessions and logins. session_start(), password_hash() and password_verify(), protecting a page. You can build a login that would survive someone reading your source code.
11 — Security in the open. SQL injection, cross-site scripting, file uploads, error display in production. You can name the escaping each situation needs and why one does not substitute for the other.
12 — Making it fast, and shipping it. Indexes and their cost, slow queries, config, deploying to a host. Your application is live, and you know which query to look at first when it slows down.
Course Highlights
🔥 Security taught inside the feature — the first query you ever write is a prepared one.
🔥 One application across twelve chapters, not twelve disconnected examples.
🔥 Industry-standard tools — Apache, phpMyAdmin, MySQL Workbench.
🔥 Free, including the test and the certificate.
Who Should Enroll?
- Beginners who want back-end development and databases from the start.
- Front-end developers who need to understand the half they keep handing off.
- Freelancers and business owners who want to build data-driven sites themselves.
The Test and Certificate
Twelve questions across the twelve chapters — superglobals, prepared statements, joins, sessions, hashing and indexing. Register, take a hall ticket, sit the timed paper, and a pass earns a certificate carrying your name, the course and the date.
Sit it now, free: take the practice test for this course. It is scored in your browser, and it is a self-assessment rather than a proctored exam.
