Get ready to build a real-world web application from the ground up using PHP, MySQL and PDO. This course walks you through setting up the right environment, building a full authentication and profile system, handling sessions and validations, creating a job and category system, and finishing with a powerful admin panel—while solving real bugs and mastering advanced techniques.
Prepare the environment and initial configuration
Before writing a single feature, you’ll learn to set up the right environment and configuration for a large project. This includes preparing your PHP and MySQL setup and organizing configuration files so your codebase is maintainable as it grows. Establishing a solid config stage makes later tasks like authentication, file uploading, database queries and the admin panel straightforward and repeatable.
During this stage you will:
- Organize project folders and config entries for database connections using PDO.
- Prepare reusable settings that let you switch environments and maintain consistent behavior across development and production.
- Lay the groundwork for secure practices you will reinforce later, such as protecting sensitive data and limiting user access.
Build authentication, profiles, sessions and validations
The core of any application that handles users is a robust authentication and profile system. You will build a complete authentication system with customizable validation layers and advanced handling of passwords, learning both hashing and un-hashing concepts as covered in the course. This phase focuses on protecting sensitive data and limiting what users can access based on their role.
Key learning points include:
- Implementing a fully validated, customizable authentication flow that covers registration, login and access control.
- Working with hashing and un-hashing passwords to understand advanced coding techniques around credential storage and verification.
- Dealing with sessions and customizing session behavior to suit different parts of the app—so job seekers and companies experience the app differently.
- Creating a full profile system and implementing best practices for updating profiles reliably and securely.
- Setting up multiple layers of validations across profiles and forms to ensure data integrity and a consistent user experience.
Design the job system, categories, search and database queries
After the authentication and profile foundation is complete, you’ll design and implement a real-world job posting system. Companies will manage jobs—creating, showing, deleting and updating—while job seekers will apply and interact with posted jobs. This part of the project demands disciplined validation and careful control of privileges to keep company and seeker operations separate and secure.
What you will build and refine:
- A job posting system that enforces validations so only authorized companies can manage jobs.
- An applying flow tailored to job seekers, integrating with profile data and access rules you’ve already built.
- A category system to organize job listings and improve discoverability.
- A multi-input search form that lets users search across several fields, combined with advanced database querying techniques like joins and wild cards to retrieve relevant results.
- File uploading workflows for attachments or profile assets, and the logic to update and delete these files safely.
- Ongoing debugging practice: you will encounter real bugs and learn systematic approaches to identify and resolve issues during development.
Create the admin panel and master under-the-hood mechanics
The final stretch ties everything together with an amazing admin panel built from start to finish. You will learn how an admin interface works under the hood, how to present and manage sensitive data safely, and how to centralize control for both job seekers and companies.
In this phase you will:
- Build an admin panel that gives full control over jobs, categories, users and uploaded files.
- Implement layered validations and role-based protections so sensitive operations are restricted and auditable.
- Work with complex database queries and UI-driven controls to manage large datasets and operations efficiently.
- Follow a practical, project-based approach with step-by-step bug fixes and real examples—guided by Mohamed Hassan, founder of Web Coding—who explains concepts clearly and answers learners’ questions.
- Understand who benefits most: people who learned PHP and MySQL and want to build a full project, developers who want to build their CVs, and aspiring programmers aiming to level up with new techniques.
By completing this course you will have built a massive, practical web application: from config and authentication to profiles, jobs, categories, searches, file uploads, debugging, and a full admin panel. If you know PHP, MySQL, PDO and a bit of Bootstrap and want hands-on, project-based learning that covers both backend logic and user-facing features, this intensive, bug-focused experience is designed for you.
