{"aaData":[["Hitech Institute","0shoaib0@gmail.com","8149587579","2016-02-04 16:55:37","5"],["Hitech Institute","0shoaib0@gmail.com","8149587579","2016-02-04 16:55:38","6"],["Hitech Institute","0shoaib0@gmail.com","8149587579","2016-02-04 16:55:40","9"],["fdsf","fds","654545","2016-02-08 13:52:40","12"],["fsdf","fsdfsdfds","546","2016-02-08 13:53:51","13"],["hjgh","hg","3123123","2016-02-08 14:35:31","14"]]}


foreach($data->aaData as $row) {
echo $row->aaData[1];   
}

它不起作用，请帮助我的人

php 有内置函数 json_decode() 下面是例子

<?php
$rs=json_decode($jsonvalue);
print_r($rs);
?>

see php official documentation

** 你的问题 o/p**

这是我更新的代码

$string="";
$data=json_decode('{"aaData":[["Hitech Institute","0shoaib0@gmail.com","8149587579","2016-02-04 16:55:37","5"],["Hitech Institute","0shoaib0@gmail.com","8149587579","2016-02-04 16:55:38","6"],["Hitech Institute","0shoaib0@gmail.com","8149587579","2016-02-04 16:55:40","9"],["fdsf","fds","654545","2016-02-08 13:52:40","12"],["fsdf","fsdfsdfds","546","2016-02-08 13:53:51","13"],["hjgh","hg","3123123","2016-02-08 14:35:31","14"]]}');
$string.="<table border=1>";
foreach ($data->aaData as $key => $value) {
    $string.="<tr>";
    $string.="<td>";
    $string.="<a href=".'yourpath/'.$value[4].">View</a>";
    $string.="<a href=".'yourpath/'.$value[4].">Edit</a>";
    $string.="<a href=".'yourpath/'.$value[4].">Delete</a>";
    $string.="</td>";
    $string.="</tr>";
}
$string.="</table>";
echo $string;

这是 o/p 你添加你的引导类和字体图标

JSON 不是数组、对象或数据结构。 JSON 是一种基于文本的序列化格式 - 所以是一个花哨的字符串，但仍然只是一个字符串。在 PHP 中使用json_decode() 对其进行解码。

$data = json_decode($json);

例如：-

$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}';
var_dump(json_decode($json));
var_dump(json_decode($json, true));

会输出

object(stdClass)#1 (5) { ["a"] => int(1) [“b”] => int(2) ["c"] => int(3) ["d"] => int(4) ["e"] => int(5) }

数组（5）{ ["a"] => int(1) [“b”] => int(2) ["c"] => int(3) ["d"] => int(4) ["e"] => int(5) }

在你的情况下，它会像

$data='{"aaData":[["Hitech Institute","0shoaib0@gmail.com","8149587579","2016-02-04 16:55:37","5"],["Hitech Institute","0shoaib0@gmail.com","8149587579","2016-02-04 16:55:38","6"],["Hitech Institute","0shoaib0@gmail.com","8149587579","2016-02-04 16:55:40","9"],["fdsf","fds","654545","2016-02-08 13:52:40","12"],["fsdf","fsdfsdfds","546","2016-02-08 13:53:51","13"],["hjgh","hg","3123123","2016-02-08 14:35:31","14"]]}';
$yourResult=json_decode($data);
echo "<pre>";
print_r($yourResult);
foreach ($yourResult->aaData as $item) {
//do something with this data
}

希望对你有帮助！

为了得到一个包含 JSON 信息的数组，你需要这样做：

$output_array=json_decode($json);

之后你可以通过

查看里面的信息

foreach ($output_array->aaData as $item) {
    //....do something
}

Answer 4

$json = '{"aaData":[["Hitech Institute","0shoaib0@gmail.com","8149587579","2016-02-04 16:55:37","5"],["Hitech Institute","0shoaib0@gmail.com","8149587579","2016-02-04 16:55:38","6"],["Hitech Institute","0shoaib0@gmail.com","8149587579","2016-02-04 16:55:40","9"],["fdsf","fds","654545","2016-02-08 13:52:40","12"],["fsdf","fsdfsdfds","546","2016-02-08 13:53:51","13"],["hjgh","hg","3123123","2016-02-08 14:35:31","14"]]}';

$data = json_decode ($json, TRUE);

foreach($data['aaData'] as $row) {
    var_dump ($row);   
}

我会使用json_decode (here documentation)，然后会设法发布数据。

Answer 5

PHP foreach 循环不直接作用于 json 数据。 您需要先在数组中解码，如下所示

$data = json_decode($JSON);
