json轉換php數組對象
Ⅰ php生成數組轉成json後,在轉化為對象
你可以參考一下我的建議，1.普通：若php關聯數組不含有中文，直接json_encode轉換。轉換之後用json_deconde（$stuJson)轉為php對象。
<?php
$stu = array("name"=>"li","age"=>"35");
$stuJson = json_encode($stu);
還有什麼疑問的話，可以多去後盾們看一下相關的視頻，這樣你更清楚
Ⅱ php 將json格式數據轉換成數組的方法
如下所示：
//json格式數據
$data
=
'[{
"F_MoleId":
"1",
"F_ParentId":
"0",
"F_EnCode":
"SysManage",}]';
//轉換成數組
$arr
=
json_decode($data,true);
//輸出
var_mp($arr);
以上這篇php
將json格式數據轉換成數組的方法就是小編分享給大家的全部內容了，希望能給大家一個參考，也希望大家多多支持腳本之家。

Ⅳ JSON PHP中,Json字元串反序列化成對象/數組的方法
如下所示：
<?php
//php反編碼解析json信息
//json_decode(json字元串);
$city
=
array('shandong'=>'jinan','henan'=>'zhengzhou','hebei'=>'shijiazhuang');
$jn_city
=
json_encode($city);
//反編碼json
$fan_city
=
json_decode($jn_city,false);//第二個參數false則返回object類型，false可以默認不寫
var_mp($fan_city);//object(stdClass)#1
(3)
{
["shandong"]=>
string(5)
"jinan"
["henan"]=>
string(9)
"zhengzhou"
["hebei"]=>
string(12)
"shijiazhuang"
}
echo
"<br
/>";
$fan_city
=
json_decode($jn_city,true);//第二個參數true則返回array類型
var_mp($fan_city);//array(3)
{
["shandong"]=>
string(5)
"jinan"
["henan"]=>
string(9)
"zhengzhou"
["hebei"]=>
string(12)
"shijiazhuang"
}
手動寫的JSON字元串一定要用單引號才能成功反序列化成對象/數組：
<?php
//json信息反編碼
//不同php版本，對「純json字元串」解析存在問題
//使用雙引號定義的json字元串反編碼操作變為null
//$jn
=
"{'name':'tom','age':'20','addr':'beijing'}";
//$fan_jn
=
json_decode($jn,true);
//var_mp($fan_jn);//NULL
//使用單引號定義的json字元串反編碼操作會成功
$jn
=
'{"name":"tom","age":"20","addr":"beijing"}';
$fan_jn
=
json_decode($jn,true);
var_mp($fan_jn);

Ⅳ php怎麼將數組數組轉化為json格式的數據
一、json_encode()
[php]view plain
<?php
$arr=array('a'=>1,'b'=>2,'c'=>3,'d'=>4,'e'=>5);
echojson_encode($arr);
?>
{"a":1,"b":2,"c":3,"d":4,"e":5}
$obj->body='anotherpost';
$obj->id=21;
$obj->approved=true;
$obj->favorite_count=1;
$obj->status=NULL;
echojson_encode($obj);
{
"body":"anotherpost",
"id":21,
"approved":true,
"favorite_count":1,
"status":null
}
- 由於json只接受utf-8編碼的字元，所以json_encode()的參數必須是utf-8編碼，否則會得到空字元或者null。當中文使用GB2312編碼，或者外文使用ISO-8859-1編碼的時候，這一點要特別注意。
輸出
[php]view plain
再看一笑祥個對象轉換的例子：
[php]view plain
輸出
[php]view plain
二、索引數組和關聯數組
PHP支持兩種數組，一種是只保存"值"（value）的索引數組（indexed array），另一種是保存"名值對"（name/value）的關聯數組（associative array）。
由於javascript不支持關聯數組，所以json_encode()只將索引數組（indexed array）轉為數組格式，而將關聯數組（associative array）轉為對象格式。
Ⅵ php關於JSON轉數組的問題
var_mp(json_decode($json,true));
json_decode — 對JSON 格式的字元串進行解碼
望採納 Thx
Ⅶ php怎麼把json解析成數組
在 php 里，對於 json 的操作，通常使用 json_encode 和 json_decode 函數，將 json 數據解析成數組使用 json_decode 函數，以下是示例代碼：
<?php
$json='{"a":1,"b":2,"c":3,"d":4,"e":5}';
var_mp(json_decode($json,true));
?>
Ⅷ json在php中的使用之如何轉換json為數組
看你怎麼傳遞這個json的.
如果是字元串傳遞過去, 那麼這個串要eval 下, 或者使用 json2.js 中的 JSON.parse(jsontext) 方法
附: json2.js 地址:
https://github.com/douglascrockford/JSON-js
或者點擊直接下載:
如果是JSONP 協議傳遞過去, 就可以直接使用;
建議採用jquery+ajax模式來處理json, 哪怕是同步的, 調用起來也比直接 post/get 來的方便.
