这是一个常见问题，我已经研究了谷歌可以提供的所有答案，所以我很抱歉再次问这个问题。

Firebug 将响应显示为

}

jsonlint.com 说 json 是有效的，但为什么 apache 将 Doctype 放在响应前面？这是导致错误吗？

Firebug 还将标题报告为：

Connection  Keep-Alive
Content-Length  798
Content-Type    application/json
Date    Wed, 23 Jan 2013 09:18:35 GMT
Keep-Alive  timeout=5, max=100
Server  Apache/2.2.22 (Ubuntu)
X-Powered-By    PHP/5.4.6-1ubuntu1.1

我正在使用来自 DataTables 的 server_processing.php 脚本

header('Content-Type: application/json');
echo $output;

我的 php 的相关部分是：

    $(document).ready(function() {
                $('#example').dataTable( {
                    "bProcessing": true,
                    "bServerSide": true,
                    "sAjaxSource": "server_processing.php",
                    "sPaginationType": "full_numbers"
                } );
            } );
        </script>
    </head>
    <body>
    <div id="dynamic">
    <table cellpadding="0" cellspacing="0" border="0" class="display" id="example">
    <thead>
        <tr>
            <th>Symbol</th>
            <th>Current Estimate</th>
            <th>7 days ago</th>
            <th>30 days ago</th>
            <th>60 days ago</th>
            <th>90 days ago</th>
            <th>% Change Current</th>
            <th>% Change 7</th>
            <th>% Change 30</th>
            <th>% Change 60</th>
            <th>Next Earnings Date</th></th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td colspan="10" class="dataTables_empty">Loading data from server</td>
        </tr>
    </tbody>
    <tfoot>
        <tr>
            <th>Symbol</th>
            <th>Current Estimate</th>
            <th>7 days ago</th>
            <th>30 days ago</th>
            <th>60 days ago</th>
            <th>90 days ago</th>
            <th>% Change Current</th>
            <th>% Change 7</th>
            <th>% Change 30</th>
            <th>% Change 60</th>
        </tr>
    </tfoot>
   </table>

我已经浪费了很多时间来解决这个问题，所以非常感谢任何帮助。

我发现了我的问题。我有一个添加文档类型的前置函数。一旦删除，一切都很好。我通过将我的代码移动到另一个没有前置的开发站点找到了它并且它有效。
