<s>[INST] ### Part 1: Learning the Basics

#### Chapter 1: Installing PHP
Before installing PHP, make sure your computer meets the minimum system requirements. PHP 7.0 requires a minimum of 128 MB RAM, although 256 MB or more is recommended. It's also recommended that your computer has a minimum Pentium III processor.
For a development environment, you can install PHP, Apache, and MySQL all at once using a package such as XAMPP or MAMP. These packages are free to download and include everything you need to get started with PHP development.
For a production environment, you can manually install PHP, Apache, and MySQL on your server. You can download the installation packages from the official websites of each software.
Alternatively, you can install PHP on a Cloud platform such as AWS or Google Cloud.

**1.1: Installing XAMPP**

XAMPP is a free and open-source package that includes PHP, Apache, MySQL, and Perl. It's available for Windows, macOS, and Linux.
To install XAMPP, follow these steps:
1. Download the XAMPP installer from the official Apache Friends website.
2. Run the installer and follow the prompts to install XAMPP.
3. Choose the components you want to install. Make sure to select PHP and Apache.
4. Choose the installation location and click "Next".
5. Wait for the installation to complete.

Note: You will be asked to install Bitnami for XAMPP. Bitnami is a package manager that allows you to easily install and manage web applications. You can choose to install it or skip it.

**1.2: Installing PHP on a Cloud Platform**

To install PHP on a Cloud platform, follow these steps:
1. Create an account on the Cloud platform of your choice (e.g. AWS or Google Cloud).
2. Create a new instance (e.g. EC2 instance on AWS).
3. Install the PHP package using the package manager (e.g. yum on Amazon Linux).
4. Configure the PHP settings as needed.

Note: The steps to install PHP on a Cloud platform may vary depending on the platform and operating system you are using.

**1.3: Verifying PHP Installation**

To verify that PHP is installed correctly, follow these steps:
1. Open a text editor and create a new file with a `.php` extension (e.g. `test.php`).
2. Add the following code to the file: `<?[/INST]
