how do I know when users press ENTER

how do I know when users press the ENTER key on textarea so I will be able to replace it with <br>?

do I do the following code?
preg_replace("\n\r","<br>",$content);

try nl2br

thank you pal, you helped me a lot. i read the comments ,which were written there, and saw that :

$text= str_replace('\r\n', '\n', $text);

well, it works as well as nl2br function but thank a lot for your support.
