捕获字符串中的新行

Question

I know for sure that this was already been asked before but I just googled around and couldn't find anything (maybe wrong word choice?). Just don't be too mad at me, I'm getting mad too...

I'd like

$string = '
This is a line
This is another line
';

to be shown to the HTML page as

This is a line
This is another line

when I do echo $string;. How can I capture the return key or the new line and replace it with <br>?

Answer 1

Try the nl2br() function:

echo nl2br($string);

Would return:

<br>
This is a line<br>
This is another line<br>

To trim off the leading and trailing new lines, use trim():

echo nl2br(trim($string));

Would return:

This is a line<br>
This is another line
