Is it possible to view code in PHP from another site that has one connection to JS? For example:

<html>
<body>
<script src="script.js"></script>
</body>
</html>

It is necessary to get the content of the site, and not this code. Is it possible? Thanks

I can offer you an interesting crutch through chrome / chromium, install
chromium and call it through shell_exec with the parameters headless / disable-gpu / dump-dom (the last flag is key for your task).
more or less like this:

$dom = shell_exec('chromium-browser --headless --disable-gpu --dump-dom https://example.ru/');

replace chromium-browser with the name of the chromium(ium) binary, and in the distribution
, in this case, chromium(ium) will start in headless mode (without a user graphical interface), without gpu support (they don’t have one hell of a thing on servers with rare exceptions), download page, all resources, will perform the entire Client-Slide-render (just this JS script), collect the DOM and return it (the collected DOM )
as a result but it's a long time to tell PPS: not through browsers / browser engines, implementation in pure PHP is extremely difficult, to put it mildly, because at least you will have to interpret JS in some way.
