"slash before every quote" problem [duplicate]

My shared web hosting adds \ to JSON. I use ExtJS and it normally sends this data
[{"property":"id","direction":"ASC"}]
Howere PHP receives or chages it as [{\"property\":\"id\",\"direction\":\"ASC\"}]
Thus I cannot use json_decode($_REQUEST['sort'])
I think this is because they wanted to prevent SQL injection but now they break my application. What I have to do?
Edit:
$sort = json_decode($_GET['sort']);
print_r($_GET); // [sort] => [{\"property\":\"id\",\"direction\":\"ASC\"}]
print_r($sort); //

Please check, if you vHost has magic quotes enabled.
Someone over here proposed this to get the unchanged values:
if (get_magic_quotes_gpc()) {
function strip_array($var) {
return ( is_array($var)
? array_map("strip_array", $var)
: stripslashes($var)
);
}
$_POST = strip_array($_POST);
$_SESSION = strip_array($_SESSION);
$_GET = strip_array($_GET);
}
