PHP，strip_tags 在文本区域中剥离 \n.如何阻止它? [英] PHP, strip_tags stripping \n in text area. How to stop it?

问题描述

我希望能够接受 \n 或 \r\n 并将它们转换为 <br/>在页面中使用.尽管当用户提交带有新段落的文本区域时，strip_tags 函数似乎会将它们直接删除.我可以做些什么来将这些保留在字符串中?

I would like to be able to accept \n or \r\n and convert them to <br /> for use in the page. Although when a user submits a text area with new paragraphs, the strip_tags function seems to strip them right out. Anything I can do to keep these in the string?

谢谢！！！

推荐答案

您可以使用 nl2br 将 BR 换行元素添加到换行符序列:

You can use nl2br to add the BR line break element to line break character sequences:

$html = nl2br($plain);

注意 BR 元素是刚刚添加的:

Note that the BR elements are just added:

nl2br("foo\nbar") === "foo\n<br />bar"

并防止 strip_tags 删除 P 和BR 标签，在第二个参数中指定:

And to prevent strip_tags to remove P and BR tags, specify them in the second parameter:

$clean = strip_tags($html, '<p><br>');
