converting BR tags into new lines in a textarea

This is a function I made which is supposed to convert every Br line break into a \n:

function br2nl($st){
    return preg_replace('/<br(\s+)?\/?>/i', "\n", $st);
}

However, the output is like this:

foo

bar

nuts

I want it to output something like:

foo <br>
bar <br>
nuts

Probably your HTML is 

foo<br>
bar<br>
nuts<br>

So you already have "\n" and replacing br to "\n" you ends up with double "\n" like

foo \n\n bar \n\n nuts

it's looks like 

foo

bar

nuts

For receiving output you suggest - you need to remove "\n" from the input HTML and then replace br to "\n"

The code would be

function br2nl($st){
  $st_no_lb = preg_replace( "/\r|\n/", "", $st );
  return preg_replace('/<br(\s+)?\/?>/i', "\n", $st_no_lb);
}
