当我使用 JSON 数据将表格格式数据检索到 PHP 中时答案

【问题标题】：while I'm retrieving the tabular format data using JSON data into PHP当我使用 JSON 数据将表格格式数据检索到 PHP 中时
【发布时间】：2017-12-10 07:37:23
【问题描述】：

我正在尝试通过将 JSON 数据调用到 PHP 代码中来将数据转换为表格格式。

用于转换为表格格式的 JSON 代码。

[

  {
   "#":"3586 "
   "Project" :"SSMT",
   "Tracker" :"Maintenance",
   "Status" : "To Do"
   "Subject" : "Test the following scenario and provide the relevant scripts in centos7"
   "Author" : "Anil K"
   "Assignee" : "SSMT Group"
  },
  {
   "#" :"3517"
   "Project" : "SSMT"
   "Tracker" : "Improvement"
   "Status" : "In Progress"
   "Subject" : "Image server daily backup"
   "Author" : "Lakshmi G"
   "Assignee" : "Pooja S"
  },
  {
   "Project" : "SSMT"
   "Tracker" : "Improvement"
   "Status" : "In Progress"
   "Subject" : "setup openstack all-in-one in centos7 instance on ORAVM1 box."
   "Author" : "Anil K"
   "Assignee" : "Bhanuprakash P"
  }
]

下面的 php 代码是用来获取上面的 JSON 数据的。

<!DOCTYPE html>
<html lang = "en-US">

<?php

$url = 'data.json';
$data = file_get_contents($url);
$characters = json_decode($data);

echo $characters[0]->name;

foreach ($characters as $character) {
         echo $character->name . '<br>';

}
?>

 <table>
        <tbody>
                <tr>
                        <th>#</th>
                        <th>Project</th>
                        <th>Tracker</th>
                        <th>Status</th>
                        <th>Subject</th>
                        <th>Author</th>
                        <th>Assignee</th>

                </tr>
                        <?php
                        foreach ($characters as $character) {
                                echo '<tr>'
                                echo '<td>' . $character-># . '</td>';
                                echo '<td>' . $character->project . '</td>';
                                echo '<td>' . $character->tracker . '</td>';
                                echo '<td>' . $character->status . '</td>';
                                echo '<td>' . $character->subject . '</td>';
                                echo '<td>' . $character->author . '</td>';
                                echo '<td>' . $character->assignee . '</td>';
                                echo '</tr>';
                        }
                        ?>
        </tbody>

 </table>

</html>

我收到以下错误 PHP Parse error: syntax error, unexpected 'echo' (T_ECHO), expecting identifier (T_STRING) or variable (T_VARIABLE) or '{' or '$' in /var/www/html/tabularformat.php on line 34

任何人都可以建议 othis 吗？ ?

添加后;在每个“回声”语句的末尾。也得到同样的错误。请找到它。

【问题讨论】：

在每个 echo 语句完成后添加 ;
PHP Parse/Syntax Errors; and How to solve them?的可能重复
已添加；半逗号，结果是一样的。
检查你的密钥，它肯定不会#
更改名称#。 #不能是变量，php中的函数名。

标签： php html json

【解决方案1】：

我建议使用true 作为第二个参数来形成数组元素。
您的 json 无效（我已在代码中修复）
您需要区分大小写访问密钥。
在尝试访问之前检查元素是否存在。

代码：(Demo)

$json='[
  {
   "#":"3586 ",
   "Project" :"SSMT",
   "Tracker" :"Maintenance",
   "Status" : "To Do",
   "Subject" : "Test the following scenario and provide the relevant scripts in centos7",
   "Author" : "Anil K",
   "Assignee" : "SSMT Group"
  },
  {
   "#" :"3517",
   "Project" : "SSMT",
   "Tracker" : "Improvement",
   "Status" : "In Progress",
   "Subject" : "Image server daily backup",
   "Author" : "Lakshmi G",
   "Assignee" : "Pooja S"
  },
  {
   "Project" : "SSMT",
   "Tracker" : "Improvement",
   "Status" : "In Progress",
   "Subject" : "setup openstack all-in-one in centos7 instance on ORAVM1 box.",
   "Author" : "Anil K",
   "Assignee" : "Bhanuprakash P"
  }
]';

$characters = json_decode($json,true);
foreach ($characters as $character) {
    echo '<tr>';
        echo '<td>',(isset($character['#'])?$character['#']:''),'</td>';
        echo '<td>',(isset($character['Project'])?$character['Project']:''),'</td>';
        echo '<td>',(isset($character['Tracker'])?$character['Tracker']:''),'</td>';
        echo '<td>',(isset($character['Status'])?$character['Status']:''),'</td>';
        echo '<td>',(isset($character['Subject'])?$character['Subject']:''),'</td>';
        echo '<td>',(isset($character['Author'])?$character['Author']:''),'</td>';
        echo '<td>',(isset($character['Assignee'])?$character['Assignee']:''),'</td>';
    echo '</tr>';
}

输出：

<tr>
    <td>3586 </td>
    <td>SSMT</td>
    <td>Maintenance</td>
    <td>To Do</td>
    <td>Test the following scenario and provide the relevant scripts in centos7</td>
    <td>Anil K</td>
    <td>SSMT Group</td>
</tr>
<tr>
    <td>3517</td>
    <td>SSMT</td>
    <td>Improvement</td>
    <td>In Progress</td>
    <td>Image server daily backup</td>
    <td>Lakshmi G</td>
    <td>Pooja S</td>
</tr>
<tr>
    <td></td>
    <td>SSMT</td>
    <td>Improvement</td>
    <td>In Progress</td>
    <td>setup openstack all-in-one in centos7 instance on ORAVM1 box.</td>
    <td>Anil K</td>
    <td>Bhanuprakash P</td>
</tr>

否则，您可以使用“封装”来访问# 对象。

$characters = json_decode($json);
foreach ($characters as $character) {
    echo '<tr>';
        echo '<td>',(isset($character->{'#'})?$character->{'#'}:''),'</td>';
        // ...

来自the manual：

示例 #2 访问无效对象属性

访问对象中包含 PHP 命名约定不允许的字符（例如连字符）的元素可以通过将元素名称封装在大括号和撇号中来完成。
$json = '{"foo-bar": 12345}';

$obj = json_decode($json);
print $obj->{'foo-bar'}; // 12345
