The $_POST array contains only variables supplied by a form that used the POST method, while the $_REQUEST array combines the $_POST, $_GET and $COOKIE arrays.

The difference between a GET and a POST is the way data is transferred to a servlet. With a GET, the URL will show each name/value pair on the query string in the URL. For example, if you had a form with a field named 'foo,' and when submitted had a value of 'bar,' the URL might be something like this: http://www.example.com/servlet?foo=bar With a POST, this information is not visible in the URL. Instead, it is transferred in the HTTP headers. As far as the actual servlet is concerned, there is not a great deal of difference when it comes to getting the parameters. Whether you use a GET or a POST, you still use request.getParameter("foo"); to get the value. The method used in the Servlet for processing either a GET or a POST is different too. If you use a GET, the method that is called is doGet(HttpServletRequest, HttpServletResponse). The doGet method is also called if there is no GET or POST data. If you use a POST, the method called is doPost(HttpServletRequest, HttpServletResponse).
$_POST and $_GET are both PHP functions used to extract input from HTML forms. However, the difference is that $_POST keeps the extracted variables hidden from users, whereas $_GET does not. Because of this, there is a major difference between the two functions in terms of security.Why would you use $_GET at all, then? Because some websites have large databases full of information for the user. For example, say you were shopping online, and you go to buy 2 pairs of pants (item #125). The URL that you are sent to might look like this:catalog.php?item=125&quantity=2As you can see, the variables obtained through $_GET are visible to the user.The POST method has possibility of much volume data sending (usually by the server settings limited) and it may be used unless it represents benefits in comparing GET method. A lot of browser can not correctly bookmark pages which are displayed after HTTP POST method, because the submitted data is displayed in the address bar.When you need the query string, which is get by GET method using (ineffective by it's limits), you will try to use POST method for your forms. You can use POST method if you submit the important information which shouldn't be displayed in the address bar.
