echo json_encode($object)."<br />";
//显示的结果为：
{id="1",siteName:"web\u7f16\u7a0b\u7ad9",siteUrl:"http:\/\/www.baidu.com"}
//+++++++++++++++++++++++++++数字索引数组++++++++++++++++++++++++++++++
$arr1=array(1,"web编程站","http://www.baidu.com");
echo json_encode()."<br />";
//显示结果为:
[1,"web\u7f16\u7a0b\u7ad9","http:\/\/www.baidu.com"]

$arr2=array("id"=>1,"siteName"=>"web编程站","sitUrl"=>"http:\/\/www.baidu.com");
echo json_encode($arr2)."<br />";
//显示结果为：
{id:1,siteName:"web\u7f16\u7a0b\u7ad9",siteUrl:"http:\/\/www.baidu.com"}
//+++++++++++++++++++++++++多维数组+++++++++++++++++++++++++++++++
$arr3=array(array(1,"web编程站","http://www.baidu.com"),array(2,"webdeveloper","http://www.sina.com"),array(3,"webcoder","http://www.qq.com"));
