Answer 1

You could use ->fetchColumn(0) to get the 1 and only column from the next (one and only) rowset.

if ( $query->fetchColumn(0) > 0 ){
  return false;
} else return true;

Likely, you'd want $query->fetchColumn();

You can also pass which column number you want, but it defaults to column 0.
