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.
