Hell no! Why would they be overwritten? An HTTP request is sent from user A, the interpreter is "compiling" the PHP script with the received HTTP request variables and send back the HTTP response to user A, during this time the same thing happens with user B. I can't think of any possible reason in which the $_POST variables will be overwritten during paralell requests.
