【问题标题】:How can I parse JSON into a html table using PHP?如何使用 PHP 将 JSON 解析为 html 表?
【发布时间】:2014-11-30 12:35:58
【问题描述】:

我必须在我的网站上找到一张桌子。并且必须从中获取该表的数据 “http://west.basketball.nl/db/json/stand.pl?szn_Naam=2014-2015&cmp_ID=373” 我已经尝试了很多东西,但没有任何效果......

 <!DOCTYPE html>
  <html>
   <head>
    <script type="text/javascript" 
       src="http://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
   </head>
   <body>
    <?php
    $json=file_get_contents("http://west.basketball.nl/db/json
    /stand.pl?szn_Naam=2014-2015&cmp_ID=373");
            $data =  json_decode($json);

        if (count($data)) {
            // Open the table
            echo "<table>";

            // Cycle through the array
            foreach ($data as $stand) {

                // Output a row
                echo "<tr>";
                echo "<td>$afko</td>";
                echo "<td>$positie</td>";
                echo "</tr>";
            }

            // Close the table
            echo "</table>";
        }
    ?>
  </body>
</html>

【问题讨论】:

  • 对不起各位...忘了说,但这是写在一个.php文件中
  • 什么不起作用?您是否在开发环境中将error_reporting 设置为E_ALLdisplay_errors 设置为on
  • 你是什么意思?....我猜不是....对php来说还是新手
  • 我想问题是由于安全原因 url_fopen 被设置为禁用。在 PHP 脚本的开头添加 error_reporting(E_ALL);。并确保在您的 .htaccess 或 php.ini 中将 display_errors 设置为 On 或在您提出请求后查看 PHP 日志文件。
  • 我不知道 php.ini 是什么,也不知道 .htaccess 是什么......,我确实添加了错误报告,但它仍然不起作用。控制台有一个错误,它关于 html 的绘图集以及它是如何未声明的以及关于 US-ASCCI 什么的?

【解决方案1】:

以下代码可用于动态转换整个表格,而无需定义列名。

 echo "<table>";
        echo "<tr>";
        foreach(array_keys($your_array[0]) as $head){
            echo "<td>$head</td>";
        }
        echo "</tr>";

        foreach($your_array as $row){
            echo "<tr>";            
            foreach($row as $col){
                echo "<td>$col</td>";
            }
            echo "</tr>";
        }
        echo "</table>";

        return $posicoes;

    【解决方案2】:

    如果你想要递归方式:

    public static function jsonToDebug($jsonText = '')
    {
        $arr = json_decode($jsonText, true);
        $html = "";
        if ($arr && is_array($arr)) {
            $html .= self::_arrayToHtmlTableRecursive($arr);
        }
        return $html;
    }
    
    private static function _arrayToHtmlTableRecursive($arr) {
        $str = "<table><tbody>";
        foreach ($arr as $key => $val) {
            $str .= "<tr>";
            $str .= "<td>$key</td>";
            $str .= "<td>";
            if (is_array($val)) {
                if (!empty($val)) {
                    $str .= self::_arrayToHtmlTableRecursive($val);
                }
            } else {
                $str .= "<strong>$val</strong>";
            }
            $str .= "</td></tr>";
        }
        $str .= "</tbody></table>";
    
        return $str;
    }
    

    然后拨打echo YourClass::jsonToDebug($jsonText)

    【讨论】:

    • 最佳答案,因为它是 1) 结构无关和 2) 代码高效(递归)
    【解决方案3】:

    为什么不试试呢:

    $data = json_decode($json, true);
    

    【讨论】:

    • 解释:第二个参数 (true) 告诉 json_decode() 返回一个关联数组而不是给定数据的对象,如果您不从事 OO 编程,使用它可能更直观。
    【解决方案4】:

    从外部来源获取数据时,首先要做的是了解返回的内容。

    也是这样

    <?php
    $json=file_get_contents("http://west.basketball.nl/db/json/stand.pl?szn_Naam=2014-2015&cmp_ID=373");
    $data =  json_decode($json);
    
    print_r($data);
    

    结果:

        [stand] => Array

    所以现在您知道您正在处理的是一个 OBJECT,而不是标量值或数组。

    所以试试这个代码:-

    <?php
        $json=file_get_contents("http://west.basketball.nl/db/json/stand.pl?szn_Naam=2014-2015&cmp_ID=373");
        $data =  json_decode($json);
    
        if (count($data->stand)) {
            // Open the table
            echo "<table>";
    
            // Cycle through the array
            foreach ($data->stand as $idx => $stand) {
    
                // Output a row
                echo "<tr>";
                echo "<td>$stand->afko</td>";
                echo "<td>$stand->positie</td>";
                echo "</tr>";
            }
    
            // Close the table
            echo "</table>";
        }
    ?>

    • 哇,非常感谢它终于起作用了 :D 你知道一种让它对位置进行排序的方法吗? 1.2.3.4.5.6.7.8.9.10.11等以此类推
    【解决方案5】:

    我猜,问题在于您使用的变量 - $afko$positie。请尝试以下代码 -

    // Cycle through the array
    foreach ($data as $stand) {
        // Output a row
        echo "<tr>";
        echo "<td> . $stand['afko'] . </td>";
        echo "<td> . $stand['positie'] . </td>";
        echo "</tr>";
    }
