execution of php script

Question

I know that when we execute a PHP script on localhost, the server runs the code and does the required processing and simply outputs the result to the browser. Recently, I was reading about socket_create function which creates a connection for server and client to communicate, but I have a doubt regarding it. Below is what I think, please correct me if i am wrong. When I run my program (which uses socket_create) by typing http://localhost/myprog.php... The prog commands localhost to make a open a socket. This is ok, but what if I want to create socket on some other server? (Below are two options, please tell me which is correct) If I still run the script on http://localhost does that mean the script will run on localhost and localhost will make a socket on the other server? And if I want to give some input to the other server the input will pass through localhost. I can't do it as told above, I would have to run my script on other server to create a socket on it.

Answer 1

PHP script is like any other program on machine. If you access script which is on localhost, and this script creates socket then script on your local machine connect to the other server, retrieves output, pass it back to script. If you access some remote host, then script is executed on this remote host - that's only difference. So the answer is 1.
