The Complete Syllabus for learning PHP

PHP is a backend server scripting language. It has been historically widely used in web development platforms like WordPress. A large number of websites run their servers with PHP.

In this blog post, we will show you the full syllabus for learning PHP from beginner to expert level.

PHP Syllabus for Beginners

1. Introduction to PHP
   • Overview of PHP and its role in web development.
   • Setting up a local development environment (XAMPP, WAMP, MAMP).
   • Understanding basic PHP syntax and structure.
2. Variables, Data Types, and Operators
   • Declaring variables and understanding variable scope.
   • Working with different data types (strings, integers, floats, arrays, booleans).
   • Using arithmetic, comparison, and logical operators.
3. Control Structures
   • Using conditional statements (if, else if, else) for decision making.
   • Implementing loops (for, while, do-while) for iterative tasks.
   • Understanding switch-case statements for multi-way branching.
4. Functions and Arrays
   • Defining and calling user-defined functions.
   • Passing arguments to functions and returning values.
   • Working with indexed arrays, associative arrays, and multidimensional arrays.
5. Working with Forms and Handling User Input
   • Creating HTML forms to collect user input.
   • Retrieving form data using PHP’s superglobal arrays ($_GET, $_POST).
   • Validating and sanitizing user input to prevent security vulnerabilities.

Intermediate Level Topics for PHP:

6. Working with Strings and Regular Expressions
   • Manipulating strings using built-in PHP functions.
   • Understanding regular expressions for pattern matching.
   • Performing string manipulation and validation tasks.
7. File Handling and I/O Operations
   • Reading from and writing to files using file handling functions.
   • Uploading files from web forms and processing file uploads.
   • Implementing file management operations (copying, moving, deleting files).
8. Error Handling and Exception Handling
   • Understanding PHP error types and error reporting levels.
   • Implementing error handling strategies (try-catch blocks) for graceful error recovery.
   • Logging errors and debugging PHP code effectively.
9. Working with Databases (MySQL/MariaDB)
   • Connecting to a MySQL/MariaDB database using PHP.
   • Executing SQL queries (SELECT, INSERT, UPDATE, DELETE) from PHP.
   • Using prepared statements and parameterized queries for preventing SQL injection attacks.
10. Sessions and Cookies
    • Managing user sessions and session variables in PHP.
    • Setting and retrieving cookies for storing user preferences.
    • Implementing session and cookie security best practices.

    • Parsing JSON and XML responses from web services.
    • Building and exposing APIs with PHP using frameworks like Laravel or Slim.
13. Web Application Security
    • Understanding common web vulnerabilities (XSS, CSRF, SQL injection).
    • Implementing security measures such as input validation, output escaping, and CSRF tokens.
    • Using HTTPS, secure sessions, and encryption for data protection.
14. Performance Optimization
    • Identifying performance bottlenecks in PHP applications.
    • Caching strategies (opcode caching, data caching) for improving performance.
    • Profiling and benchmarking PHP code for optimization.
15. Testing and Test-Driven Development (TDD)
    • Writing unit tests using PHPUnit or other testing frameworks.
    • Implementing test-driven development practices for writing robust and maintainable code.
    • Performing integration testing and continuous integration (CI) with PHP projects.
16. Advanced Topics and Emerging Technologies
    • Exploring PHP frameworks and libraries (Laravel, Symfony, CodeIgniter).
    • Understanding PHP’s role in modern web development (microservices, serverless architecture).
    • Keeping up with the latest trends and advancements in the PHP ecosystem.
