json从sql数据库输入数据while循环

Question

我有一个json的代码，但我不知道如何输入while循环。

我有代码编辑的内容，但我没有一个想法如何while while循环一个JSON，因为我正在分心的下一行它意味着下一张图片右尝试添加一个它的作品，但不'不知道如何插入，这里是示例的链接。

这里是我while循环和查询码

$query=mysql_query("select * from persons order by date desc LIMIT 0,10 "); 

> <img height=200 width=200 src=' upload/". $test['Image'] ."'/> <a href 
> ='profile.php?PersonID=$id'> ".$test['LastName'].", ". $test['FirstName']." ". $test['MiddleName']."</a> 

，这里是我的脚本文件来调用代码

> agile_carousel_multiple_slides_visible_example.html 
> 
> <script> 
> 
>  $.getJSON("agile_carousel_data.php", function (data) { 
> 
>   $("#multiple_slides_visible").agile_carousel({ 
>    carousel_data: data, 
>    carousel_outer_height: 230, 
>    carousel_height  : 200, 
>    slide_height   : 200, 
>    carousel_outer_width : 480, 
>    slide_width   : 260, 
>    number_slides_visible: 3, 
>    transition_time  : 330, 
>    control_set_1: "previous_button,next_button", 
>    control_set_2: "group_numbered_buttons", 
>    persistent_content: "<p class='persistent_content'>Agile Carousel Example: Multiple Slides Visible</p>" 
>   }); 
> 
>  }) 
> 
> </script> 

尝试这种代码，但赢得了” t输出任何东西

客户端，你的循环应该是这样的：

//first assign the entire Array to var whatever 
for(var i in whatever){ 
    var eachObject = whatever[i]; 
    for(var n in eachObject){ 
    var eachObjectValue = eachOject[n]; 
    } 
} 

如果你只是想访问，说第三对象在你whatever数组中的第2个值将是这样的：

whatever[2].content_button or whatever[2]['content_button'];
