Discover why PHP is a popular web scripting language, install PHP on a web server, and build a more sophisticated, beginner-friendly hello world application.
Install PHP with XAMPP using the all-in-one distribution from Apache Friends, which bundles Apache, PHP, MySQL, and Perl; customize components, start Apache, and verify via localhost.
Access the php.net documentation quickly using shortcuts and aliases to reach the manual. The manual auto-redirects to your browser language, with the English version usually up-to-date and Windows installation pages.
Explore handling checkboxes and radio buttons, ensuring explicit name and value attributes, and manage single and multi select lists with proper array naming, square bracket syntax, and server post data.
Escape user input before output by applying htmlspecialchars to data sent to the browser to prevent cross-site scripting, and use ENT_QUOTES to also escape single quotes.
Enhance PHP form validation with Perl compatible regular expressions, using preg_match to validate inputs like emails and dates, and provide detailed error messages to improve usability.
Learn to manage drop-down and multi-select lists, radio buttons, and checkboxes in PHP, using the selected attribute to reflect choices and in_array to detect languages.
Explore how forms submit data using post or get, validate text fields, preserve user input in prefilled form fields, and defend against cross-site scripting by escaping output with htmlspecialchars.
Modify the users table by adding a password and is_admin columns, then use PHP 5.5+ password hashing API to securely store and verify passwords with password_hash and password_verify.
Learn to securely store passwords by hashing them with the password hashing API using the default encryption algorithm, insert the hash into the database, and verify hashes during login.
Learn how to validate passwords in a PHP and MySQL setup by creating a login form, querying the users table, fetching the password hash, and verifying it with password_verify.
Manage state across web requests in PHP by using sessions and cookies, initialize with session_start, and store data in $_SESSION for persistent user information.
Explore building a sample PHP application by including external files with require and include, using the password hashing API for secure passwords, and managing sessions to persist data.
PHP powers nearly 80% of the web. It is the engine behind WordPress, Facebook, and Wikipedia.
If you want to build dynamic, data-driven websites, you must learn PHP and MySQL. HTML and CSS are just the paint; PHP is the machinery that makes the web work.
Welcome to The Ultimate PHP & MySQL Developer Course. This course is designed to take you from a complete beginner to a capable Backend Developer. We don't just teach you syntax; we teach you how to build secure, robust applications that can handle real users.
Why learn PHP? It is the most popular server-side language in the world. Learning PHP is the fastest way to get hired as a freelancer or full-time developer because the demand for maintaining and building PHP apps is massive.
What will you build? We believe in learning by doing. Throughout this course, you will build a Content Management System (CMS) from scratch. This isn't a toy project; it will include:
Secure Login/Registration Systems: Learn to hash passwords and manage sessions.
CRUD Operations: Create, Read, Update, and Delete data from a database.
Admin Panels: Build restricted areas for administrators to manage content.
What will you master?
1. The Fundamentals
Understand variables, loops, arrays, and functions.
Master the Request/Response cycle (GET vs. POST requests).
2. The Database (MySQL)
Learn to design Relational Databases.
Write SQL queries to insert, select, and filter data.
Visual Learning: We will sketch out Entity Relationship Diagrams (ERDs) so you understand how tables link together.
3. Security Essentials
The web is full of threats. You will learn to prevent SQL Injection and XSS (Cross-Site Scripting) attacks.
Learn best practices for password encryption and data sanitization.
4. Advanced Techniques
Object-Oriented Programming (OOP): Move beyond procedural code and write clean, reusable classes.
PDO (PHP Data Objects): Learn the modern, secure way to connect PHP to databases.
Who is this course for?
Front-End Developers who want to become Full-Stack engineers.
