A basic PHP autoloader setup
View 0.autoload_setup.php
* In this example, we are autoloading classes within the namespace `Acme\ExampleProject`. The file `index.php` is the
* entry point to our project; and we are using the `src` directory to store and organize our PHP class files. Our
* autoloader is located in `autoload.php`
* The basic behavior is illustrated in the fact that PHP will autoload the file `src/mammals/human.php` whenever we
* attempt to create a `new \Acme\ExampleProject\Mammals\Human` anywhere in our project's codebase.
* This diagram illustrates our project structure. Each file's contents can be found below.

Exploring the definition of a function in math and how it can inform my understanding of functions in programming
View 0.no_inputs.php
* This function has no inputs, so it is not a function from a mathematical
* perspective. Furthermore, the function is not predictable because it depends on
* the state of the underlying program
