That would be false. you cannot -
start a browser
connect to a remote http(s) service
which responds with content
then have that content interact and execute a local PHP script.


If PHP is interactively (or via a cron job etc...) running, the box on
which it is running would be considered a server for that "application". I
think you are confusing client-server paradigm vs. a server paradigm.

PHP or even the remote server itself does not/cannot know that PHP is even
running on our "client". And even if it could, that would be a HUGE
security risk - which is why it cannot be done.

PHP is a scripting language. It does work and sends a response to stdout.
Where, in the context of a web server, stdout is the connection to a
remote browser. In the context of a terminal session (or CMD prompt et.
al.) stdout can be redirected to an output file or to the "terminal
session". Typing the command "php file.php" (or whatever) means that you
are executing it on this box. It does not interact with PHP on a remote
box - therefore it is server only.
