Q3: php 循环判断，判断json里面的数据，大神们帮帮忙啊

$str = '{"queryString":"select id , name from user LIMIT 0, 30 ","data":[{"0":"1","id":"1","1":"aa","name":"aa"},{"0":"2","id":"2","1":"\u5c0f\u4f19\u4f34","name":"\u5c0f\u4f19\u4f34"},{"0":"3","id":"3","1":"\u5c0f\u4f19\u4f34","name":"\u5c0f\u4f19\u4f34"},{"0":"4","id":"4","1":"44","name":"44"},{"0":"5","id":"5","1":"","name":""},{"0":"6","id":"6","1":"","name":""},{"0":"7","id":"7","1":"","name":""},{"0":"8","id":"8","1":"","name":""},{"0":"9","id":"9","1":"","name":""},{"0":"10","id":"10","1":"jiejie","name":"jiejie"},{"0":"11","id":"11","1":"jiejie","name":"jiejie"}]}';

foreach (json_decode($str) as $v)

{

if(is_array($v))

{

foreach($v as $value)

{

echo "当前的name 为: {$value-name} id : {$value-id}";

}

}

}

中文不管 你取得是对应的name值

Q4: PHP循环读取JSON

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

}

Q5: php 循环输出 json 数组

?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
