用&#39;替换&#39;\\ n&#39;最简单的方法是 <br> &#39;？

Question

I found some answers in the questions, but I didn't understand and AJAX was used in those solutions.

Now I want to find an easy solution to replace "Enter Key" or \\n with <br> to find new lines, in JavaScript or PHP.

For a text input(visitors comments) in a <form> .

Is there any way to use string.search() and don't using AJAX or Jquery or some harder solutions?

Answer 1

PHP的内置函数nl2br（）可以做到这一点。

Answer 2

nl2br是最简单的

<?php echo nl2br($_POST['someTextArea']); ?>

Answer 3

Use nl2br in PHP to change new lines to break tags. http://php.net/manual/en/function.nl2br.php

Answer 4

The easiest and most reliable way to do this is using PHP's built in nl2br() function.

However, it looks like you would like to achieve this using javascript. That can be done using this:

value.replace(/\n/g,'<br />')
