用mysqli_real_escape_string提交的数据中带有格式，输出数据也是带有格式

由于数据进行了验证我用了mysqli_real_escape_string，这样数据在数据库中直接显示如\r\n 这样的格式，我在显示页显示的时候发现数据没有显示该有的样式（换行，加粗，数据一般都是直接复制网上的内容，有的带了格式），而是直接现在下图效果

这是什么情况产生的？

\r\n 是文本文件的回车换行
而页面是 html 语言，有他自己的换行符


nl2br()

\r\n 是文本文件的回车换行
而页面是 html 语言，有他自己的换行符


nl2br()


我这个是直接从网页上复制下来的，按说不会有你说的这样的问题啊

\r\n 是文本文件的回车换行
而页面是 html 语言，有他自己的换行符


nl2br()


nl2br() 函数在字符串中的每个新行 (\n) 之前插入 HTML 换行符 (
)。
那我是不是要在数据添加的时候就做处理？这个要怎么解决？
