Req #72579 [Com]: Support (array)-casting for objects

Edit report at https://bugs.php.net/bug.php?id=72579&edit=1 ID: 72579 Comment by: geiger at karim dot email Reported by: geiger at karim dot email Summary: Support (array)-casting for objects Status: Feedback Type: Feature/Change Request Package: Class/Object related PHP Version: Next Major Version Block user comment: N Private report: N New Comment: Thanks for the quick response. I didn't know that function and it does pretty much what I intend to do, but the problem is: I have to call it manually. I'd love to see that function being invoked automatically when casting to an array, since that's the point of having a cast option after all. In my mind it's not consistent to be able to foreach through an object as expected but getting something completely different when casting it to an array.

There are many options to get to where I want to be, for example implement an interface having a toArray() method, but all of that is quite inconsistent, I think. I can see how having yet another magic __toArray()-method may not be a good thing, since it just raises more questions and problems, so I'd rather suggest something, which I think is the next logical step. As you all know, we are already able to implement interfaces like ArrayAccess, Countable, and Iterator. If we've done all that, we're almost where we want to be: Having an object act like an array. We now are able to use it in a foreach loop, assign, unset and alter values using the array-syntax ($foo[] = 'bar';), etc. The only thing that does not work is casting it to an array. If we do so, we'll always get an key-value-pair of its properties. I can see where that's useful, but if we already have all that methods on that object (offset*, next, key, valid, ...), why don't we use them? I'm suggesting the following behaviour: If a plain object with no interfaces gets casted to an array, maintaining the key-value-conversion is a great idea. But, if the object implements the (or a) Iterator-interface, why can't we "foreach" through that object and combine its keys and values in a true array, making it compatible to all (PHP)-functions and the array type? I hope this isn't a duplicate entry of some other feature request I didn't find. If not, I'd love to hear your opinion on this and if you think this makes sense. Best regards Karim Test script: --------------- Since this example implements the Iterator interface, it's a bit too long to paste here. You can visit the Gist at: https://gist.github.com/KarimGeiger/e3e4fbc4a1ec8c6564347b8a2a217334 Expected result: ---------------- array(2) { 'foo' => string(3) "bar" 'baz' => int(123) } Actual result: -------------- array(1) { '\0*\0items' => array(2) { 'foo' => string(3) "bar" 'baz' => int(123) } } ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=72579&edit=1
