html - Replacing a newline with a <br> - PHP

Question

I'm guessing this is something you can do in PHP. What I want is to get the text in a textfield when the submit button is pressed and convert all the newlines into

<br>'s.

Help, please?

Answer 1

nl2br would do what you want, I think.

<?php
$str = "

foo
bar";
echo nl2br($str);

Output:

<br />
<br />
foo<br />
