Master PHP Programming: From Beginner to Advanced Developer

Learn to create variables in PHP with the dollar sign and dynamic typing. Understand integers, floats, and booleans, and practice output with the dot operator and if-else.

Master PHP concepts by defining constants with define, using single and double quotes for strings, performing arithmetic on numbers, and handling single-index arrays.

Master PHP programming explores control structures, including if-else and switch-case, to enable decision making and varied outputs with booleans, break statements, and default scenarios.

Explore PHP loops for, while, do-while, and foreach, and learn to execute code multiple times, process data, and iterate arrays like colors red, green, and blue.

Explore multidimensional arrays in PHP by building a 2d student data structure with names and scores, then print results and sort arrays in ascending and descending order using sort.

Master foreach in PHP to iterate over numeric and associative arrays, accessing keys and values. See practical examples with colors and student scores.

Explore the basics of PHP object-oriented programming by creating a car class with a public property for the model and a display method, then instantiate and use objects.

Discover how constructors initialize object properties and destructors clean up resources in PHP, demonstrated with a user class and a name property, showing a user is created and destroyed.

Learn how inheritance lets a PHP class inherit properties and methods from a base class, using a vehicle example with car and bike. See how polymorphism overrides methods in subclasses.

Explore interfaces and abstract classes in PHP, learning how interfaces define required methods and how abstract classes offer abstract and concrete methods through inheritance, with practical PHP examples.

Explore the three main PHP error types—syntax errors, runtime errors, and logical errors—and see how missing semicolons, division by zero, and incorrect calculations speed up debugging.

Master PHP programming teaches you to handle errors with try-catch, catching exceptions to prevent crashes and display user-friendly messages for conditions like division by zero or file not found.

Learn how to connect PHP to MySQL using both MySQLi and PDO, compare procedural and object-oriented approaches, set up DSN, handle errors, and build dynamic data-driven websites.

Connect PHP to a MySQL database and perform create, read, update, and delete operations, then execute a select query to fetch and display user names and emails.

Master PHP programming by performing insert, update, and delete operations on a MySQL database to manage user records and build dynamic, data driven web application.

Create and handle forms with PHP by building a simple HTML form connected to a PHP script that processes posted username and email and shows a confirmation.

Learn to handle get and post requests in PHP by building a search form using get and a login form using post, with secure data handling and proper HTML escaping.

Learn to validate PHP form inputs by enforcing required fields and email formats, with practical examples of a registration form's name validation and email validation using post method.

Read from a file in PHP by checking file existence and retrieving content with file_get_contents, then write to output.txt using file_put_contents with success or error messages.

Master PHP file uploading and handling files by building a web form with post method and multipart/form-data, validating uploads, and saving to a server directory with a unique name.

Create a simple PHP API that handles a GET request to return a JSON array of users with id and name. Output uses application/json.

Master handling JSON data in PHP by encoding and decoding JSON, and fetching and decoding JSON from an API request to work with API responses.

Demonstrate password hashing with PHP using password_hash to generate secure hashes for password storage. Show encryption with openssl_encrypt using a random initialization vector and CBC mode.

Learn how to secure file uploads and form handling in PHP by validating uploads, restricting mime types to images and pdfs, and sanitizing user input to prevent cross-site scripting.
