E-Commerce Website Using PHP and MySQL

Overview

An E-Commerce website is an online platform that enables businesses to sell products or services over the Internet. Customers can browse through the website, view product details, add items to their cart, and proceed to checkout to make a purchase. PHP is a widely used server-side scripting language that can be used to build dynamic and interactive web applications, including E-Commerce websites.

E-Commerce Planning and Design

Step 1: Define Requirements

Determine the scope of your E-Commerce website. What products will you sell? What features are essential?

Step 2: Wireframing and UI Design

Create wireframes to visualize the layout and user flow. Design an intuitive user interface for product listing, details, cart, and checkout

Setting Up the Environment for Development

Install a local development environment with a web server (e.g., Nginx*) and PHP*

Installing Nginx and PHP on an Ubuntu 20.04

Install Nginx

sudo apt update
sudo apt install nginx

This will install the Nginx web server on your system. After the installation, Nginx should start automatically. You can check its status using:

sudo systemctl status nginx

Install PHP

sudo apt install software-properties-common

sudo add-apt-repository ppa:ondrej/php

sudo apt install php libapache2-mod-php php-mysql

Verify the Installation

To verify that Nginx and PHP are working correctly, create a simple PHP file and check it in your browser:

echo "<?php phpinfo(); ?>" | sudo tee /var/www/html/phpinfo.php

Open your web browser and enter http://localhost/phpinfo.php in the address bar. You should see a page displaying PHP information.

Restart

After making changes, it's important to restart Nginx to apply them

sudo systemctl restart nginx

You've successfully installed Nginx and PHP on your system. You can now start developing and hosting your PHP-based websites.

💡

Please note that these instructions are for a basic setup. Depending on your project's requirements and the specific Linux distribution you're using, there might be additional steps or configurations needed.
