Learn how to upload files with PHP by building a practical form, handling the files array, and moving uploads to an uploads folder with success or error feedback.

Understand how a database stores, accesses, and updates data for web apps. Learn relational databases like MySQL and how PHP uses SQL to store and retrieve data.

Master SQL, the structured query language for relational databases, and perform create, read, update, and delete operations across MySQL, PostgreSQL, and SQLite using phpMyAdmin.

Connect php scripts to a mysql database using the mysql extension to read, store, and manage data like users and posts. Create the database and establish the connection in db_connect.php.

Master CRUD operations with PHP and MySQL by creating a users table, inserting data, and reading records. This lesson also covers updating and deleting data and displaying results.

Update and delete records using PHP and MySQL by editing user data, updating specific IDs with SQL, and removing entries to manage dynamic web apps.

Compare sessions and cookies in PHP, then learn to set and retrieve cookies, start and read sessions, and secure user data on the server across pages.

Build a secure login and registration system with PHP and MySQL, creating a database and a users table, using prepared statements, password hashing, and session handling for authenticated users.

Create a login system using a login form with email and password posted to login.php, using PHP sessions, a database connection, prepared statements, and password verification for secure access.

Learn to implement a complete logout system and robust user management in PHP and MySQL, including session handling, password hashing, redirects, and secure authentication.

Plan and build a custom cms with php and mysql by outlining features, file structure, admin dashboard, authentication, posts and categories management, uploads, and a public blog page.

Create a robust admin panel for a CMS by building a dashboard to manage posts and categories, including add/edit posts, session login, and a bootstrap layout with header and footer.

Create new blog posts in PHP as part of CRUD by adding posts via an admin form, inserting title and content into the database with prepared statements.
