Don't use PDO but assuming you want to loop through a result set,
shouldn't this line:-
if ($row = $sth->fetch(PDO::FETCH_ASSOC)) {
be
> while ($row = $sth->fetch(PDO::FETCH_ASSOC)) {
Also you need to test if the result set is empty or not.
I don't have an "easy" way to convert Postgres arrays into PHP style
arrays. What I ended up doing was to use the array_to_string function
in the select statement using the underscore character as the delimiter
in the string, and then converting the string to a PHP array via an
explode. However, I've only had to do this with single level arrays.
Don't know if this helps as you haven't supplied the table definition
of words_games.
Cheers,
Rob
