One line of code. That’s all you need in order to get your sandbox. Developers often need a place where the can experiment with design ideas or Minimal Viable Productions. This tutorial will show you how to do this.

1. Download WordPress from https://wordpress.org/download/
2. Unzip the files.
3. Delete the file wp-config-sample.php
4. Download the file wp-config.php from your WordPress on your web host.
5. Edit wp-config.php in your favorite editor.

If you have WordPress up and running the settings in wp-config.php will be almost the same. But you have to change one line of code, if you want to run more than one WordPress installation on your web host.

wp-config.php

Find this line:

$table_prefix = 'wp_'; 

// change this line to:

$table_prefix = 'sandbox_';

If you need more WordPress on your web host, just change the table prefix every time.
