Task Description

The aim of this assignment is to create an online store to sell a product of your choice. Compile a PHP code using these steps.

Specific requirements are listed later in this manual. Here is a broad overview:

$$ The store sells one particular kind of product $($e$.$g$.,$ video games, supplements, clothes, etc.$)$

$$ Within this product, you should have $3$ categories $($e$.$g$.,$Adventure$,$Shooter$,$Puzzle$,$ etc.$)$

$$ Within each category, you should have $3$ products $($e$.$g$.,$Mario$,$Zelda$,$Metroid$,$ etc.$)$

$3$ categories x $3$ products $=9$ total products in the store.

$$ Each product will have a price associated with it$.$

$$ A $$customer$$ should be able to choose what products they want to purchase from the store,

and your website should calculate their $$total price$.$

The requirements are listed below, along with examples of a store that sells TVs$.$

Note: your store should not sell TVs$.$ Otherwise, you will just be copying the example.

Task Requirements

$1.$ Your code should be clean, and follow good coding practises $[5$ Marks$].$

Good code will have the following qualities:

i$.$ Comments are used to explain the logic of your code. You don$$t have to explain your basic

code, syntax, etc. Instead, explain why your code is written a certain way $($e$.$g$.,$ what your

if$-$statement is checking, what your array represents, etc.$).$

ii$.$ Variables have sensible$,$ human$-$readable names $($e$.$g$.,$ $categories is better than $c$).$

iii. Use indentation inside if$-$statements, loops, function definitions, multi$-$line arrays, etc.

iv$.$ Proper spacing around operators, function parameters, etc. $($e$.$g$.,$

$choice $==$ $categories$[$$i$]$ is better than $choice$==$$categories$[$$i$])$

v$.$ No redundant code $($i$.$e$.,$ code that doesn$$t do anything, or is just used for testing, etc.$)$

$2.$ Any PHP file that you make should have the following code at the bottom, so that the source

code is shown on the page $[1$ Mark$].$

echo $"$
