Don't mix foreach() and next(). Change the test around to avoid it, and
use break to quit the test after a successful match (make sure that
your data is sorted by gallery).
foreach ($data as $line)
{
// ...
if( $g == $gallery )
{
// ...do the table output here...
// then get out of the loop:
break;
}
}
// this should be outside the foreach() loop:
echo '</table>';
