How do I get variable to a PHP file from another PHP-file?

Yes, a PHP website can be shared with another Windows machine. One common way to do this is to set up a local web server on the machine where the website is hosted, and then make the website accessible over the network. This can be done using software such as XAMPP, WAMP, or IIS. Once you have set up the web server, you can access the website from another Windows machine by entering the IP address of the hosting machine in a web browser. For example, if the hosting machine has the IP address 192.168.1.100, you can access the website by entering http://192.168.1.100 in a web browser on the other Windows machine. Please note that for security reasons, it's not recommended to share a PHP website over a public network without proper protection, such as using SSL encryption. 

  You can pass a variable from one PHP file to another by including the first file in the second file using the  include  or  require  statement and then accessing the variable with the global keyword. For example: File: first.php $variable = "value"; File: second.php include 'first.php'; echo $variable; You can also pass variables between PHP files using the session, cookie or query string. The query string method involves adding the variables to the URL when redirecting to the second page.
