**Course Title:** Mastering CodeIgniter Framework: Fast, Lightweight Web Development **Section Title:** Version Control, Deployment, and CI/CD **Topic:** Using Git for version control in CodeIgniter projects In this topic, we'll delve into the world of Git, a version control system that will revolutionize the way you collaborate, manage, and deploy your CodeIgniter projects. Git is a widely used tool in the industry, and by the end of this topic, you'll be able to work seamlessly with it, making you a proficient CodeIgniter developer. ### Introduction to Git Before we dive into using Git for version control, let's cover the basics: **What is Git?** Git is a distributed version control system that helps you track changes in your codebase. It allows you to work on a copy of the repository and make changes, which can then be synchronized with the original repository. **Git Command-line Interface** The Git command-line interface is a powerful tool that allows you to perform various Git operations. It's composed of various commands, including: * `git init`: Initializes a new Git repository * `git clone`: Clones an existing repository * `git add`: Adds files to the staging area * `git commit`: Commits changes to the repository * `git log`: Displays the commit history **Basic Git Concepts** * **Commit**: A commit represents a snapshot of your codebase at a specific point in time. You can create a new commit using the `git commit` command. * **Branch**: A branch is a separate line of development in your repository. You can create a new branch using the `git branch` command and switch between branches using the `git checkout` command. * **Remote repository**: A remote repository is a central location where your collaborators can access and pull your code. ### Installing Git and Configuring Your Profile Before using Git, you'll need to install it on your computer and configure your profile. Follow these steps: **Install Git** To install Git, visit the official Git website and follow the instructions for your operating system: [Download Git from GitHub](https://git-scm.com/downloads) **Configure Git** After installing Git, open a terminal and run the following commands to configure your profile: * `git config --global user.name "Your Name"` * `git config --global user.email "your.email@example.com"` **Add Remote Repository** After installing and configuring Git, add the CodeIgniter project as a remote repository using the following command: `git init.` (in your CodeIgniter project directory) `git remote add origin https://github.com/username/project.git` (replace `https://github.com/username/project.git` with the actual repository URL) **Example** Suppose we want to initialize a new repository, clone the existing one, and configure the Git profile. We would perform the following operations: * `git init`: Initialize a new repository in our local machine. * `git clone https://github.com/username/project.git`: Clone the existing repository. * `git config --global user.name "Your Name"`: Configure our Git profile. **What to Try** Create a new Git repository using `git init.`, add files using `git add.`, commit using `git commit -m "Initial commit"`, and clone an existing repository using `git clone`. Open your newly cloned repository, run `git log` to display the commit history, and run `git remote` to list remote repositories.
