Casting objects.

Hello.

I've got an object via odbc_fetch_object (which is of stdClass).

I have an class structuresRemovalReason.

I want to cast the response of odbc_fetch_object to structuresRemovalReason.

The only way I can see of doing this is to not use odbc_fetch_object,
but odbc_fetch_assoc and then iterate the array and populate a new
structuresRemovalReason.

Or an I missing a trick. I'm pretty sure I am.

Regards,

Richard Quadling.

Something like this in your class or another class may work (not
tested). You might even fetch an array and send it to this method. I
think either should work:

class structuresRemovalReason {

static public function cast(structuresRemovalReason $object) {
return $object;
}
}

$row = structuresRemovalReason::cast(odbc_fetch_object($result));

Never mind, that was stupid. I saw that somewhere before, but obviously
it doesn't work.

I found some code, maybe I redeem myself?

static public function cast(&$object, $class=__CLASS__){

if(class_exists($class)) {
$object = unserialize(
preg_replace('/^O:[0-9]+:"[^"]+":/i',
'O:'.strlen($class).':"'.$class.'":',
serialize($object)));
}
}

$row = odbc_fetch_object($result);
structuresRemovalReason::cast($row);

That's an interesting approach.

Though I'm going to use reflection. I realise I need to hold some of
the data in strings where the data is not a string (datetimes for
example).

So, using a docblock with a customtag and this seems to be working just fin=
e.

Extended ReflectionClass and ReflectionProperty.

Thanks,

Richard.

Hi,
i think it will be important since more PHP Developer are using Design
Patterns. I think the cast functionality should be implemented once...
