2. How to Start Coding in PHP: Essential Tools and Setup?

The first step in your PHP programming journey is to set up your development environment. Start by installing a local server such as XAMPP, WAMP, or MAMP, which simplifies the process of running PHP scripts on your computer. These packages come with PHP, MySQL, and Apache pre-configured, enabling you to run server-side applications seamlessly.

After setting up your local server, choose a code editor or Integrated Development Environment (IDE) to write PHP code. Popular options include Visual Studio Code, Sublime Text, and PHPStorm. Each tool offers syntax highlighting, debugging capabilities, and other features that enhance the coding experience.

To start coding, create a new folder within the server’s root directory (e.g., `htdocs` for XAMPP). Inside this folder, you can create your PHP files with a `.php` extension. For instance, creating a file named `index.php` allows you to write the first line of PHP code. Start with the basic opening and closing tags:
