Use preg_match_all from form post submission url

Question

I have been using preg_match_all from URL's where we can fetch data using GET method, but how do I get data using POST method. In my case, I want to fetch PNR details from http://www.indianrail.gov.in/pnr_Enq.html (which is a form that posts data) and fetch all required details. I know form post using jQuery but how do I go about using preg_match_all in PHP?

PHP does this for you and presents you all variables available from HTTP request in the form of superglobals: http://php.net/manual/en/reserved.variables.get.php

In your case there's $_POST superglobal array which contains all variables parsed from current HTTP POST request: http://php.net/manual/en/reserved.variables.post.php
