How to preserve line breaks in textarea?

Question

I went through similar questions on this issue but couldn't find a solution. I have a simple textarea in which text will be pasted or entered directly.

How do I preserve those line breaks?

Right now line breaks will just be ignored, but when I print_r($_POST) and inspect the output in the Chrome Developer Console it still has the original text breaks. How can I display those when showing the submitted data?

Answer 1

Right now line breaks will just be ignored

No, it is still there. The key you miss is that what you enter goes as ASCII code LF ( 0xA ) but this makes no effect in HTML unless the text is displayed as preformatted block ( <pre> ... </pre>). If not, then line break is represented by <pre> ... </pre>). If not, then line break is represented by
tag so what you need to do if you want to display entered text is to convert LF s to
(you can use nl2br() function to do that) or use ` block.

正如Marcin所指出的，按照此答案中的指示显示数据时，请使用nl2br（） ： https : //stackoverflow.com/a/6480671/6206601

Answer 3

You can use nl2br() function:

Inserts HTML line breaks before all newlines in a string

echo(nl2br($_POST));
