num_row with PDO
There is no num_row() function for PHP PDO
Here are my two solutions:
One with prepare & execute:
db->prepare($sql); $sth->execute(array($key)); $rows = $sth->fetch(PDO::FETCH_NUM); echo $rows[0]; One with query:
db->query($sql); $row = $result->fetch(PDO::FETCH_NUM); echo $row[0];
