Really? That would be very strange indeed.

I just tested it and it is indeed as you state. Thanks for pointing that
out -- is this documented?

I don't quite follow you here. Why did they have no choice? I don't see
why they (c|sh)ould not call the constructor before setting the data.
After all, that would be the only logical and sensible thing to do. If
you would do this "manually", you would do it like this:

foreach ( $rows as $row ):
$item = new MyClass( 'foo', 'bar' );
foreach ( $row as $name => $value ):
$item->$name = $value;
endforeach;
$result[] = $item;
endforeach;

And I guess it would be impossible to do it the other way round (first
setting data, then calling constructor). The setting of the data can be
controlled using the magic __set() method, so there's no need for
__pdoconstruct(), if I understand you correctly.

A more intelligent approach may have been to define an interface which
any "result row" class must implement and which defines a method like
setData( $rowAsArray ). Or maybe even better: make use of the existing
__set_state() magic method.

Greetings,
Thomas
