receive get parameters in url in wordpress

Question

I make a ul menu in wordpress like this:

<li><a href="<?php get_page_link(); ?>?show=game" class="android-prim-menu-active">بازی ها</a></li>
    <li><a href="<?php get_page_link(); ?>?show=app">app</a></li>
    <li><a href="<?php get_page_link(); ?>?show=request">request</a></li>
    <li><a href="<?php get_page_link(); ?>?show=report">report</a></li>
    <li><a href="<?php get_page_link(); ?>?show=last">live</a></li>

Now, every of these links send a GET request to current page and I want to handle content with received values from GET request.

How do i use GET method in wordpress? Can I use $_GET["show"] and receive my values?

Thanks...

Use

  $_GET["show"]
  method and you can 
  echo $_GET["show"] 
  this and you will get the value
