php 5.4
<?php
header("Content-Type: application/json; charset=UTF-8");
header("Access-Control-Allow-Origin: *");
//获取请求参数
$req = $_REQUEST["req"]; 

//去掉反斜杠
//$req = stripcslashes ( $req );
$arr = json_decode ( $req, true );
print_r($arr);
?>

php 5.2

php 5.4
<?php
header("Content-Type: application/json; charset=UTF-8");
header("Access-Control-Allow-Origin: *");
//获取请求参数
$req = $_REQUEST["req"]; 

//去掉反斜杠
//$req = stripcslashes ( $req );
$arr = json_decode ( $req, true );
print_r($arr);
?>
