PHP中的json_encode没有返回正确的结果

Question

我正在尝试将数据输入到具有 CRUD 操作（称为 Jquery JTable）的网格中，但是从 MYSQL 表到 JSON 的 Json 转换似乎存在某种错误，以便将数据显示在表上它需要看起来像这样：

{
    "Result":"OK",
    "Records":[
      {"PersonId":1,"Name":"Benjamin Button","Age":17,"RecordDate":"\/Date(1320259705710)\/"},
      {"PersonId":2,"Name":"Douglas Adams","Age":42,"RecordDate":"\/Date(1320259705710)\/"},
      {"PersonId":3,"Name":"Isaac Asimov","Age":26,"RecordDate":"\/Date(1320259705710)\/"},
      {"PersonId":4,"Name":"Thomas More","Age":65,"RecordDate":"\/Date(1320259705710)\/"}
    ]
}

但是每当我在 php 中实现 json_encode 函数时，它都会给我这个：

{
    "Result":"OK",
    "Records":[
        {"0":"1","PersonId":"1","1":"Benjamin Button","Name":"Benjamin Button","2":"17","Age":"17","3":"2011-12-27 00:00:00","RecordDate":"2011-12-27 00:00:00"},
        {"0":"2","PersonId":"2","1":"Douglas Adams","Name":"Douglas Adams","2":"42","Age":"42","3":"2011-12-26 00:00:00","RecordDate":"2011-12-26 00:00:00"},
        {"0":"3","PersonId":"3","1":"Isaac Asimov","Name":"Isaac Asimov","2":"26","Age":"26","3":"2011-12-28 00:00:00","RecordDate":"2011-12-28 00:00:00"},
        {"0":"4","PersonId":"4","1":"Thomas More","Name":"Thomas More","2":"61","Age":"61","3":"2011-12-27 00:00:00","RecordDate":"2011-12-27 00:00:00"},
        {"0":"5","PersonId":"5","1":"Ihsan Oktay Anar","Name":"Ihsan Oktay Anar","2":"44","Age":"44","3":"2012-01-03 20:55:02","RecordDate":"2012-01-03 20:55:02"}
    ]
}

这是我的 PHP 代码：

<?php

//Get records from database
$result = mysqli_query($conn, "SELECT * FROM people;");

//Add all records to an array
$rows = array();
while($row = mysqli_fetch_array($result))
{
    $rows[] = $row;
}

//Return result to jTable
$jTableResult = array();
$jTableResult['Result'] = "OK";
$jTableResult['Records'] = $rows;
print json_encode($jTableResult);

?>

该表名为 people，它有四个字段：personId、Name、Age 和 RecordDate。

任何想法将不胜感激。

Answer 1

您可能想试试mysqli_fetch_assoc() 函数。

因为根据关于mysqli_fetch_array()的PHP文档：

以关联、数字数组或两者的形式获取结果行

这就是您现在使用代码所遇到的情况，因为默认获取模式是MYSQLI_BOTH：

... "1":"Benjamin Button","Name":"Benjamin Button" ...

您也可以使用mysqli_fetch_array()，但您必须调整获取模式：

mysqli_fetch_array($result, MYSQLI_ASSOC);
