Are there services for viewing the php code of the site?

Question

PHP

There is a site like site.ru/index.php. When you switch to it, a generated image of a certain size appears.
Question: are there any services that will show the code that generates this image (in other words, index.php itself)?

Answer 1

Only clean, already interpreted html code is passed to the browser without php variables and operators.

Answer 2

There are no services, but there are people. They are called hackers. It is expensive (especially if the Pentagon website), and is not approved by law

Answer 3

No and will not be
Possible only with direct access to the server

Answer 4

Gitlab/github/bitbucket

Answer 5

Look at the source code of the page, maybe there will be the name of the script/library that generates the image, which will then be googled by you.
Or yes, just access the site and watch the scripts.
