我的数据库中有狡猾的字符存在一些问题，这要归功于编码不当的过滤器脚本（当然是由您自己创建的！）。
我通过将数据从PHPMyAdmin导出为SQL文件来修复数据，然后煞费苦心CTRL+H搜索＆amp;替换正确的字符。然后我使用PHPMyAdmin重新导入了SQL文件（好吧，三个单独的文件）。
这对大多数数据都有效，但在一些帖子上，它们似乎完全被切断了。

然而出于某种原因，正如您可以看到物种概况（并且它在数据库中完全相同），大部分文本都缺失。
任何可能导致此问题的想法？导入完全没有错误。
修改
我尝试用\r\n替换###字符只是为了查看数据输入是否正确 - 但事实并非如此。

最后，这是编码问题。当我最初将我的SQL数据拆分为两个单独的文件时，新文件的默认编码为ANSI，原始版本（以及我的数据库为UTF-8）。
将编码更改为UTF-8后，我看到了大量奇怪的小字符，我的文本编辑器无法搜索到这些字符。取代
我将编码设置回ANSI，使用UTF-8创建了一个新的文本文档，只需将ANSI文档中的信息复制粘贴到新的UTF-8文件中。
以上所有内容均在Notepad++中完成。
问题解决了 - 7个小时的诊断问题;修复不到5秒钟。

如果您使用的是PHP，请使用mysql_real_escape_string（）：这就是正在发生的事情
mysql> select "<strong>Temperature</strong>: [temp]\r\n\r\n<strong>pH</strong>:";
+--------------------------------------------------------------+
| <strong>Temperature</strong>: [temp]
<strong>pH</strong>: |
+--------------------------------------------------------------+
| <strong>Temperature</strong>: [temp]
<strong>pH</strong>: |
+--------------------------------------------------------------+
1 row in set (0.00 sec)
所以使用php函数来准确存储数据。
