这似乎是将文本区域的内容直接插入到HTML中。
在表单的文本区域中，换行符按预期显示。但在表单之外，HTML不会格式化换行符（它会将所有空格折叠为一个空格）。
在HTML中有各种创建换行的方法，但在这里最简单的方法是用<br/>标记替换换行符。PHP甚至有一个函数nl2br()可以做到这一点。
值得注意的是，没有对用户输入进行清理就发布它，可能会导致跨站点脚本攻击（https://owasp.org/www-community/attacks/xss/），允许恶意用户在您的用户浏览器中运行任意JavaScript。
英文:
It looks like you're putting the contents of that textarea directly into html.
In textarea in forms, linebreaks are displayed as expected. But outside of forms, html does not format linebreaks (it collapses all whitespace in to a single space).
There are various ways to create linebreaks in html, but the simplest method here would be to replace the linebreak with the <br/> tag. php even has a function to do this nl2br()
It's worth noting, though, that posting user input without sanitizing it can result in Cross-site scripting attacks (https://owasp.org/www-community/attacks/xss/) that allow malicious users to run arbitrary javascript in your users' browsers.
