Question

I am performing an sql query using PDO. In the resulting PDOStatement, there is only one column. If i use PDOStatement->fetch(); would it serve my purpose?

Answer 1

Yes, although fetchColumn() would probably be more convenient as the return value will be scalar.

echo $stmt->fetchColumn();

otherwise you could do the following, or many variations of

$row = $stmt->fetch(PDO::FETCH_NUM);
echo $row[0];
