I was blown away that you can actually combine PDO::FETCH_CLASS | PDO::FETCH_CLASSTYPE | PDO::FETCH_UNIQUE, because both PDO::FETCH_CLASSTYPE and PDO::FETCH_UNIQUE say they will use the first column, but it turns out PDO::FETCH_CLASSTYPE goes first and then PDO::FETCH_UNIQUE will use the next column. This way you can create an associative array of objects, with one of the table columns as key. For example a query such as
'SELECT Class, Id, t.* FROM subscriptions_tbl t'
might give you this result:
Array
(
[20481086] => WConsumerSubscription Object
(
[Variant] => 2
[_Expiration:WSubscriptionModel:private] => DateTime Object
(
[date] => 2018-08-08 00:00:00.000000
[timezone_type] => 3
[timezone] => UTC
)
[Notes] =>
[Id] => 20481086
[_Deleted:protected] => 0
[_VersionNo:protected] => 2
[ContactId] =>
[ConsumerId] => 2
)
[21878324] => WAdminSubscription Object
(
[Variant] =>
[_Expiration:WSubscriptionModel:private] =>
[Notes] =>
[Id] => 21878324
[_Deleted:protected] => 0
[_VersionNo:protected] => 1
[ContactId] =>
)
)
