## Quick Start Demo Deployment Using XAMPP
|
|
|
|
|
|
1. Download PHP server. Use a server such as [XAMPP](https://www.apachefriends.org/index.html) to be able to host the demo code sample.
|
|
|
2. Browse to the `htdocs` directory of XAMPP. Unzip the downloaded demo code folder and place it in this `htdocs` directory.
|
|
|
3. Start the Apache server in XAMPP from the XAMPP control panel.
|
|
|
4. Open the website in the browser and access it as: `http://<your_domain>/<php_code_folder_name>/index.php`
|
|
|
Here, `your_domain` will be localhost if hosting on your local machine.
|
|
|
The `php_code_folder_name` is the name of the folder under which the downloaded code resides.
|
|
|
5. Read further instructions when `index.php` in opened in a browser.
|
|
|
|
|
|
1. If you have a newer version of XAMPP, launch the XAMPP control panel. In the General tab, click on Start to start the XAMPP stack.
|
|
|
2. In the Services tab, start the Apache service.
|
|
|
3. In the Volumes tab, click on Mount to mount the `/opt/lampp` volume. Then click on Explore which will launch the file explorer. Go to `htdocs` directory there and unzip the downloaded code sample there.
|
|
|
4. In the Network tab, enable port forwarding for `localhost:8080 -> 80 (over SSH)`.
|
|
|
5. Next, open your browser and go to the `localhost:8080/<Code sample folder name here>/` to launch the web application.
