Yes, but note that PHP is not compiled and it doesn't need any javascript.

PHP (recursive acronym for "PHP: Hypertext Preprocessor") is a widely-used
Open Source general-purpose scripting language that is especially suited
for Web development and can be embedded into HTML.
.....
Example:
<html>
<head>
<title>Example</title>
</head>
<body>
<?php
echo "Hi, I'm a PHP script!";
?>
</body>
</html>
Notice how this is different from a script written in other languages like
Perl or C -- instead of writing a program with lots of commands to output
HTML, you write an HTML script with some embedded code to do something (in
this case, output some text). The PHP code is enclosed in special start and
end tags that allow you to jump into and out of "PHP mode".
What distinguishes PHP from something like client-side JavaScript is that
the code is executed on the server. If you were to have a script similar to
the above on your server, the client would receive the results of running
that script, with no way of determining what the underlying code may be.
You can even configure your web server to process all your HTML files with
PHP, and then there's really no way that users can tell what you have up
your sleeve.

PHP has a full set of FTP functions, so I suppose it's possible for someone
to set up PHP script to download files from an FTP site to the server and
then upload them to their own FTP site. If you are running the script then
it's possible that your ISP would recognise this and count it as your
traffic.
