Course overview

PHP is a widely used server-side scripting language for building dynamic websites, web applications, content management systems, and backend services. It works closely with HTML, CSS, JavaScript, and databases such as MySQL.

This course introduces PHP syntax, variables, operators, control structures, functions, arrays, strings, object-oriented programming, forms, sessions, cookies, file handling, MySQL integration, validation, authentication, security, error handling, and deployment concepts.

The proposed capstone is a PHP Web Application for a chosen approved use case. It covers user registration and login, CRUD functionality, database integration, validation, security practices, documentation, and deployment readiness.

A secure PHP application needs more than working pages. It needs input validation, output escaping, prepared statements, session protection, proper error handling, and least-privilege database access.

Capstone project

PHP Web Application

Build a complete PHP Web Application for a chosen approved use case. Possible examples include a task manager, book library, blog, product catalogue, event registration system, inventory tracker, or another suitable educational web application.

Core project requirements

  • Define the application purpose, users, and success criteria.
  • Plan pages, database tables, and user flows.
  • Create a responsive HTML and CSS interface.
  • Create a MySQL database with appropriate tables and relationships.
  • Implement user registration, login, and logout functionality.
  • Use password hashing for stored credentials.
  • Implement CRUD functionality for at least one main resource.
  • Use prepared statements for all database queries.
  • Validate form input on the server.
  • Escape output to reduce cross-site scripting risk.
  • Use sessions for authentication and protected pages.
  • Implement role-based access where appropriate.
  • Handle errors and display useful user feedback.
  • Document setup, database configuration, and deployment steps.

Quality requirements

  • Use consistent naming conventions for files, functions, and database fields.
  • Separate configuration, database access, and presentation logic where practical.
  • Do not store passwords, API keys, or database credentials in plain text.
  • Use environment-based configuration for database credentials.
  • Use prepared statements to reduce SQL-injection risk.
  • Escape user-generated content before displaying it.
  • Validate all user input before saving it to the database.
  • Use secure session settings and regenerate session IDs after login.
  • Restrict file uploads by type, size, and storage location.
  • Do not display detailed database or server errors to end users.
  • Use meaningful Git commits and maintain a README.
  • Document limitations and recommended next steps.

A secure PHP application should validate input, escape output, use prepared statements, protect sessions, hash passwords, and avoid exposing sensitive configuration or error details.

Suggested project structure

Keep configuration, database access, business logic, templates, and public assets organized for maintainability.

php-web-application/
├── config/
│   └── database.php
├── includes/
│   ├── header.php
│   ├── footer.php

└── .gitignore

Do not commit database credentials, private keys, production configuration files, or user-uploaded private files to a public repository.

PHP application workflow

PHP projects are iterative. User feedback, security reviews, testing results, and changing requirements may require updates to pages, database tables, validation rules, or deployment configuration.

Plan

Define the application

Identify users, pages, database tables, and required features.

Design

Create the interface

Build responsive HTML, CSS, forms, and navigation.

Database

Model the data

Create tables, relationships, constraints, and sample data.

Develop

Add functionality

Build forms, CRUD operations, authentication, and user feedback.

Secure

Protect the app

Apply validation, escaping, prepared statements, and session security.

Deploy

Release safely

Test, configure the environment, deploy, and maintain the application.

Prepared statements separate SQL logic from user input, helping reduce SQL-injection risk; output escaping helps reduce cross-site scripting risk.
