How to display the content of Git branches with PHP, but without checkout?

Question

PHP

Good day!
The task is the following: is it necessary to display the content of the branches of the Git Repository in some way using PHP (as I understand it, through `proc_open()`), and without a "physical" checkout? Example: github, bitbucket - when switching branches through the web interface, checkout on files does not occur, but the files themselves (/folders/content) are displayed as needed. How can I do that?
