Learn PHP Basics

Learn how to output content with PHP by embedding <?php ... ?> in HTML and using echo, then render text like hello world within a proper doctype.

Learn how to reuse PHP code by using include and require to bring in external files, manage failures, and render PHP content within HTML.

Explore how PHP uses dollar-sign variables and automatically handles data types in the PHP basics course, then examine strings, numbers, booleans, arrays, and objects with basic class and function usage.

Explore php arrays, including zero-based indexing and accessing items by key. Use echo or print to output arrays, and apply sorting, counting, and associative arrays with keys like first name.

Learn the difference between single and double quotes in php when echoing content, focusing on variable interpolation in double quotes, literal strings in single quotes, and escaping apostrophes with backslashes.

Learn how PHP conditional statements evaluate booleans to control page output with if, else, and else if, including default values and handling false scenarios.

Explore PHP switch statements to simplify complex conditionals and manage dynamic values. Learn to define cases, use break and default, and produce precise output based on numeric or string inputs.

Explore PHP looping with while, do, for, and foreach to control flow, increment variables, and generate outputs. Learn how proper conditions prevent an infinite loop and streamline code.

Learn how PHP built-in and user-defined functions work, how to call them, pass arguments, set default values, and return results, while managing local and global scope.

Learn how object oriented PHP uses classes to group data and functions, create objects from a class, and call the same methods on multiple objects while keeping each object self-contained.

Explore object oriented PHP building on procedural PHP with classes, properties, and methods. Learn to pass arguments, update object data, and return values such as hello world.

Explore object-oriented PHP basics by creating multiple objects of the same class, updating properties, invoking methods, and concatenating outputs to demonstrate independent object states.
