Re: Proposal: ArraySerializable interface
I am personally (currently) relying on the approach where array conversion
gives me the values of the various properties as objects (when they are
objects), so I wouldn't like another magic operator in there (to deal
with/workaround).
Wondering why this approach would be better than doing a recursive array
map iteration.
Pardon my naive and inelegant way of dealing with maps (see the running
example at http://3v4l.org/ZOodL ):
class ObjectToArrayConverter
{
/**
* @param mixed $value
*
* @raturn array
*/
public static function toArray($value)
{
if (! (is_object($value) || is_array($value))) {
return $value;
}
if (is_object($value) && method_exists($value, '__toArray')) {
return $value->__toArray();
}
return array_map(__METHOD__, (array) $value);
}
}
