This introductory lesson establishes the foundation for PHP development by guiding students through setting up a local PHP environment for testing and development purposes. It covers running PHP scripts using the built-in server command (php -S localhost:8000) and introduces the Quiz App project that will serve as the practical application throughout the course. The lesson concludes with basic PHP output methods using echo and print statements for displaying content to users.
This lesson introduces the fundamental building blocks of PHP programming through variables and data types. It covers the proper syntax and conventions for declaring and using variables in PHP, along with an exploration of the core PHP data types including strings for text data, integers for whole numbers, and booleans for true/false values. These concepts form the essential foundation for storing and manipulating data in PHP applications.
This lesson explores the various operators available in PHP for performing calculations, comparisons, and logical operations. It covers arithmetic operators for mathematical calculations, assignment operators for storing values in variables, comparison operators for evaluating relationships between values, and logical operators for combining multiple conditions. The lesson also explains how these operators combine to form expressions and how PHP evaluates these expressions to produce results.
This lesson introduces conditional statements as essential control structures for creating decision-making logic in PHP applications. It covers the implementation of if, else, and elseif statements for executing different code blocks based on specific conditions. The lesson demonstrates practical application by showing how to use conditionals to check user answers in the quiz application, enabling the program to respond differently based on user input and create interactive functionality.
This lesson explores loop structures in PHP for automating repetitive tasks and efficiently processing data collections. It explains the practical benefits of using loops in programming and covers the implementation of for loops for controlled iteration over a specific number of repetitions. The lesson also introduces foreach loops specifically designed for iterating through arrays and collections, demonstrating their application in displaying quiz options and managing multiple data items efficiently.
This lesson introduces arrays as powerful data structures for organizing and storing collections of related information in PHP. It covers the basics of array creation and usage, with particular focus on associative arrays that use named keys to store questions and their corresponding answers in a structured format. The lesson teaches techniques for accessing array elements dynamically, enabling flexible data retrieval and manipulation essential for building interactive applications like the quiz project.
This lesson introduces functions as reusable code blocks that organize and modularize PHP applications. It covers the creation of custom functions including proper syntax and naming conventions, along with techniques for passing arguments to functions and returning values for further processing. The lesson demonstrates practical application by developing a dedicated function to evaluate quiz answers, showing how functions can encapsulate specific functionality and make code more organized, maintainable, and reusable.
This lesson focuses on essential security and data integrity practices through comprehensive form validation techniques in PHP. It emphasizes the critical importance of validating user input to prevent errors and security vulnerabilities, covering methods for checking empty fields and ensuring required data is provided. The lesson teaches validation techniques for specific data types such as ensuring text-only input in name fields, along with input sanitization methods to prevent common security issues like injection attacks and data corruption.
This lesson integrates HTML and PHP to create the user interface components of the quiz application. It covers the creation of HTML forms that can submit user answers to PHP scripts for processing, demonstrating the essential connection between frontend user interfaces and backend processing logic. The lesson teaches techniques for dynamically displaying quiz questions using a combination of PHP logic and HTML markup, showing how server-side programming can generate interactive and personalized web content.
This capstone lesson completes the quiz application by implementing form data processing and persistent score tracking functionality. It covers handling form submissions using the $_POST superglobal to capture and process user input, along with an introduction to PHP sessions using session_start() for maintaining user data across multiple page requests. The lesson demonstrates practical implementation of session-based score storage and updating, enabling the quiz application to remember user progress and maintain state throughout the entire quiz experience.
