定制网站建设可以根据自己的需求进行定制，网站制作、成都网站设计构思过程中功能建设理应排到主要部位公司网站制作、成都网站设计的运用实际效果公司网站制作网站建立与制做的实际意义
json_decode(),将json转换成对象，第二个参数为true时就是转换成数组

中文不管 你取得是对应的name值
首先你要把JSON数据转成数组，因为在php中JSON就是一个字符串。
$jsonData = '{"list": [{
"goodsid": 4290,
"post": [{
"param": "uin",
"name": "账号"
}, {
"param": "goodsid",
"name": "商品ID"
}, {
"param": "number",
"name": "下单数量"
}]
}, ';
// 你的JSON数据有点乱，我复制的可能不对
$aryData = json_decode($jsonData, true); // 转码为数组
var_dump($aryData); // 打印
foreach ($aryData as $item) {
var_dump($item); // 打印每个条目
}
?php
$Tdata='[{"A_Name":"a1","ICNo":"","A_ContNo":"","A_QQNo":""},{"A_Name":"a2","ICNo":"","A_ContNo":"","A_QQNo":""},{"A_Name":"a3","ICNo":"","A_ContNo":"","A_QQNo":""}]';
$arr=json_decode($Tdata,true);
//var_dump($arr);
echo stripcslashes ($arr[0][A_Name]);
?
上面的方法可以打印输出，json_decode($Tdata）输出的结果是一个对应，而json_decode($Tdata,true）输出的是一个数组
