Object Oriented Programming (OOP) in PHP - Build An OOP Site

Explore the basics of object oriented programming in PHP by defining a class (Badie) and creating an object instance (Gannon), then inspecting it with var_dump.

Learn how properties function as class variables in PHP OOP, define a public property like evilness, and access it from outside the class using the -> operator.

Learn how to define and use methods inside a PHP class, including public functions, returning values, and using this to modify an object's properties like evilness.

Define a body class in PHP with a public evilness property and methods to set its value; instantiate two bodies and update their evilness from 10 to 15 and 20.

Learn how constructors, the magic __construct method, run whenever a new object is created in PHP, initializing properties like evilness and leveraging the class name for messages.

Explore how a constructor assigns initial property values in PHP objects, using this to set evilness and name from input parameters during object creation.

Learn how destructors run when objects are destroyed, using unset to remove variables and how a destructor can display the class name, illustrating PHP object lifecycle.

Explore the __toString magic method to control what an object echoes, define it to display the object's name or other details, and modify output without changing downstream code.

Build a PHP object oriented game 'higher or lower' using classes, a constructor to assign random numbers, and a destructor to recreate objects, while flushing timed output to the browser.

Extend the body class to create a boss subclass, reusing its properties and methods. Override the evilness default and demonstrate a destructor-based boss behavior.

Override a method in a subclass while preserving the parent behavior by using the scope resolution operator to call the parent destruct function, then trigger the level ending.

Explore public, protected, and private properties in PHP, demonstrating how getters and setters control access, how protected allows subclass access, and how private keeps data inside the class.

Explore static properties in PHP, using a public level variable, accessed via the scope resolution operator without object creation, illustrating class-wide variables shared across the script.

Discover why object oriented programming in PHP helps organize large web apps, upgrade features, and fix bugs, and build a reusable site and page class template.

Develop two PHP classes, site and page, in a classes folder and enable autoloading to load them automatically, then verify by creating a page object.

Define header and footer files in the site class and provide public methods to assign them, then create header.php and footer.php to be included on every page.

Learn to render a PHP object‑oriented page by creating a display method that outputs header, photo, and footer using include statements, preparing content for the page.

Explore how to display page content using a page class, integrate title and content into header and footer, and render a complete PHP-based site through an OOP approach.
