I think the main benefit it offers is the ability to control what happens during
a cast operation. Right now, casting simple scalar values or NULL to an array
works as expected.
While it's possible to cast an object to an array, the semantics of what should
happen in this situation are not nearly as clear. This really should be
controlled by the class.

Hi guys. I'm dragging this out from the "History". I think this is a great suggestion
as I use a lot of object that implement ArrayAccess so doing this
$someArray = (array) $obj;
that calls $obj->__toArray() would be a GREAT addition to PHP logic.

// MY APPLICATION'S INTERIM SOLUTION (**UPDATE**)
$customers = new Customers();
$customers = $customers->__toArray(); // THIS LINE IS THE **UPDATED** LINE NEEDED IN ORDER TO
AVOID TRIGGERING THE FOLLOWING ERROR ON THE FOLLOWING LINE: Only variables should be passed by
reference
$lastCustomer = array_pop($customers); // SUCCESS
echo $lastCustomer->getName(); // prints the last customer's name since the previous line
did not fail since I explicitly called a custom method named __toArray() first

<?php
// AS-IS
$customers = new Customers();
$lastCustomer = array_pop($customers); // FAIL: array_pop() expects parameter 1 to be array, object
given
echo $lastCustomer->getName(); // execution never reaches this line
// MY APPLICATION'S INTERIM SOLUTION
$customers = new Customers();
$lastCustomer = array_pop($customers->__toArray()); // SUCCESS
echo $lastCustomer->getName(); // prints the last customer's name since the previous line
did not fail since I explicitly called a custom method named __toArray() first
// TO-BE
$customers = new Customers();
$lastCustomer = array_pop($customers); // SUCCESS
echo $lastCustomer->getName(); // prints the last customer's name since array_pop() calls
__toArray() internally before failing

Because of the magic __toString I was able to write a String class with the same methods as the Java
String class.
I was trying to write an Array class to map the one in Adobe AS3, but then I came across the lack of
__toArray.
I don't want a __toArray, or even a toString
I want classes with reasonable methods and not lots of functions with no naming rules nor parameter
order standard.
I know it may sound rude but that's how I feel when I see a language getting so far and still
not following any coding convetion.
