Here is a function which works for files pasted from browser screens:

function clean_up($dirty_file)
	{
	$contents = file_get_contents ($dirty_file);
	if ($contents)
		{
		$c_array = explode ("\n", $contents);
		$n = count($c_array);
		$i = 0; $j = 0; while ($i < $n)
			{
			$line = trim($c_array[$i]);
			if ($line != '')
				{
				$d_array[$j++] = $c_array[$i];
				}
			++$i;
			}
		$clean = implode ("\n",$d_array);
		$data_file = file_put_contents($data_file, $clean);
		}
	}		

The virtue of this is you don't have to know, or care, what characters are on the blank
lines.
