@ :  to avoid warning 

$_GET : An associative array of variables passed to the current script via the URL parameters.

myval : parameter

--

example

http://example.com/?myval=test
echo @$_GET['myval']; will echo test

http://example.com/
echo @$_GET['myval']; will be null
//php 5.4 way is
var_dump(isset($_GET['myValue']) ? : null);

The @ symbol is an error suppressor operator. It is not recommended to use it everywhere. Also, it is twice slower than the isset() function. See full reference for the @ error control operator at http://php.net/manual/en/language.operators.errorcontrol.php

It assigns value of GET parameter myValue into tmp if exists. If not - then tmp = null

PS: it is a bad practice. Better way to do the same is:

$tmp = isset($_GET['myValue']) ? $_GET['myValue'] : null;
