处理数据库报告中的换行符
新手问题在这里。
我有一个带有文本区域的网络表单，用户自然也会输入换行符。我将此表单存储到数据库中的表中。我还必须据此创建一份报告。所以我将表转储为文本并尝试解析它。对我来说，多个记录之间的分隔符是换行符。但文本区域中的新行字符使我的脚本失效。
我确信以前一定有人遇到过这种情况。您能给我建议如何处理这个问题吗？ 我尝试将文本区域中的文本放在双引号中，但这会使我的解析逻辑复杂化。我想知道是否有更简单的方法来处理这个问题。
Newbie question here.
I have a web form with a text area and naturally users will enter newline characters also. I am storing this form to a table in the DB. I also have to create a report from this. So I dump the table to text and am trying to parse it. The delimiters for me between multiple records is a new line character. But the new line character in the text area is throwing my script off.
I am sure someone must have run into this before. Can you suggest me ideas as to how to deal with this?
I tried having the text from the text area in double quotes but that will complicate my parsing logic. I was wondering if there is an easier way to deal with this.

我认为简单的答案是某种形式的逃避。
您可以在 SQL 中执行一些查找/替换，例如 REPLACE(thetext, '\n', '\\n')，或者如果换行符不重要，您可以执行 REPLACE(thetext, '\n', ' '）
I think the simple answer is some form of escaping.
You could do some find/replace in the SQL, such as REPLACE(thetext, '\n', '\\n'), or if the newlines are not important, you could do REPLACE(thetext, '\n', ' ')
最近遇到了同样的问题。最好的方法是在数据转储期间（或在数据到达数据库之前）用其他内容替换换行符。我选择了类似

Recently ran into the same issue. Your best best is to replace the newline characters during the data dump (or before the data gets to your database) with something else. I opted for something like
//or<br>so that I can recover the new lines later.我正在尝试建立一个论坛。问题是当某些用户输入 HTML 时。当您显示他的帖子时，它会被翻译。当显示他的帖子时，我无法移动到下一行。这可能对你有帮助。顺便说一句，我正在使用 PHP。
I was trying to build one forum. The problem was when some user enters HTML. It would get translated when you display his post. And I was not able to move to next line when displaying his post. This might help you. I'm using PHP by the way.
