PHP Regular Expression Help. Delete lines with nothing but spaces.

I'm looking for a regex to delete lines that only have spaces  or tabs on them, and NOT delete all line feeds. So a line with just a  \n or \r would stay, but spaces\tabs and a \n or \r would be deleted

This appears to work:

$data = preg_replace("/^[\t ]+\r?\n/m","",$data);
