html - 里面的文本格式没有了，怎么回事？

Question

我在 <textarea></textarea> 中输入了一些文本, 我输入了一些换行符、空格等。故意。但是，在提交文本并在 <pre></pre> 内呈现之后, 换行符，空格消失了，它们被类似 \r\n\r\n 的东西所取代， 怎么了？如何保持原始格式？

 <textarea name="detail" id="detail" rows="7" cols="60" style="font-family:Arial, Helvetica, sans-serif"><?php echo $detail ?></textarea>

我用 HTML 呈现文本。

这是输出:
