Preserving Line Breaks from TextArea Input

When utilizing a textarea for user input, you may encounter the challenge of preserving line breaks during output. New lines entered in the textarea often disappear once displayed, leaving your text as a continuous stream.

$input = "This\r\nis\n\ra\nstring\r";
echo nl2br($input);

is<br />
a<br />
string<br />
