I seem to remember preg_match() expects the pattern as the first, and
the string as the second argument. It appears to have worked for you the
other way around, however... is this interchangable?

Anyway, I'd split up the string and check each line separately:

$data_array=explode("\n",$data);
foreach ($data_array as $line) preg_match( [...] )
