PHP page

$shoucangId=$_GET['shoucangId'];//获取传递的参数
$where="ID='$shoucangId'";
$signalInfo=array();
$signalInfo=$this->db->get_one($where,'*','',''); //此处借用PHPCMS二次开发的例子，select数据库中的一个数据集，存于数组$signalInfo中
if($signalInfo!=null)
{
 $str=$signalInfo['title'].",".$signalInfo['url'].",".$signalInfo['type'].",".$signalInfo['id'];//将要返回的数组用逗号拼接成字符串返回
 exit($str);
