How do I retrieve string at server?

Answer 1

If you're talking about the query string, it's in the environment variable QUERY_STRING.  In C, you get it through

strcpy(query, getenv("QUERY_STRING"));

In PHP,

$query = $_SERVER['QUERY_STRING'];

If it were via post instead of get, you'd read in CONTENT_LENGTH bytes from standard input (stdin in C or php://input in PHP).
