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); } } Marco Pivetta http://twitter.com/Ocramius http://ocramius.github.com/ On 11 December 2013 02:23, chobie <chobieee@gmail.com> wrote: > Hi, > > I've got an idea for adding common way to convert array from object: > ArraySerializable interface and to allow the changing of existing > array conversion mechanism. > As an example of this change, consider the following code-snippet: > > $person = new StdClass(); > $person->name = "John"; > $phone = new StdClass(); > $phone->number = "12345"; > $person->phone = $phone; > > var_dump((array)$person); > #array(2) { > # ["name"]=> > # string(4) "John" > # ["phone"]=> > # object(stdClass)#2 (1) { > # ["number"]=> > # string(5) "12345" > # } > #} > > Currently, the implicit object to array conversion does not work > recursively.
