Function to strip returns

I'm trying to write a function that will trim and strip new line
character returns from submitted $_POST values. Does this look serviceable?

function trim_data($formdata)
  {
   foreach ($formdata as $key => $value)
       {
         $value = preg_replace("(\r\n|\n|\r|\t)", "", $value);
         $newdata[trim($key)] = trim($value);

      }
   return $newdata;
  }
