如何用PHP格式从textarea中读取换行符？
问题描述：
How can I read the New-line so that when users fill in a text-area inside my form, and then hit submit, the text is displayed exactly the same way as they wrote it?
I should mention I read in the variables from the form with POST method in my php file.
Thanks
如何阅读换行符，以便用户填写表单内的文本区域，然后 点击提交，文本的显示方式与它们写的完全相同吗？ p>
我应该提一下我在php文件中用POST方法读取表单中的变量。 p>

答
The newline character in PHP is presented by the string "
".
If you want to reproduce the newlines of your users input in HTML, you have to convert every
to a <br />. You could do that by hand or use the function nl2br in such a way:
echo nl2br($_POST['input']);

Take a look at the nl2br function.
Example from documentation:
<?php echo nl2br("foo isn't bar"); ?>The above example will output:
foo isn't<br /> bar
