Installation

Prerequisites

• PHP 5.6 or higher
• MySQL 5.7 or higher
• Web server (Apache/Nginx)
• Composer (optional for dependency management)

Steps

1. Clone or download the repository to your web server directory

git clone https://github.com/your-username/ci3-user-management.git

2. Navigate to the project directory

cd ci3-user-management

3. Install dependencies (if using Composer)

Database Setup

Create the database

CREATE DATABASE task CHARACTER SET utf8 COLLATE utf8_general_ci;

Create the users table

CREATE TABLE `users` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(255) NOT NULL,
  `email` varchar(255) NOT NULL UNIQUE,
  `password` varchar(255) NOT NULL,
  `role` enum('user','admin') DEFAULT 'user',
  `created_at` timestamp DEFAULT CURRENT_TIMESTAMP,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

Create an initial admin user

INSERT INTO users (name, email, password, role)
VALUES ('Admin User', 'admin@example.com', '$2y$10$...', 'admin');

Note: Use BCRYPT to hash the password before inserting.
