How to detect a line break in a multiline textfield

Hi can someone give me the code to convert a line break in a multiline
textfield to a <br/tag ? It's something to do with CR LF but I can't
find the exact code anywhere.
Cheers,
Ciarán

nl2br converts line break to HTML br tag.
If you want to change from <br/tag to CRLF, do a str_replace instead.
I've no recollection any functions that will convert br tag to CRLF
(as far as i know anyway)

Thanks for the reply Hendri. I got it sorted out using a simple find
and replace I found by searching for nl2br thanks to your second
post.

Converting textarea line breaks to <brin PHP
$result = str_replace(array("\r\n", "\r", "\n"), "<br />",
$thestring);

Converting <brto textarea line breaks in PHP:
$result= str_replace(array("<br/>", "<br>", "<br />"), "\n",
$thestring);

Hope this helps someone,
Ciarán
