Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

This is expected, indirect modifications through ArrayAccess is not
supported (for now), that means
$b =& $obj['foo']; $b = 2;
$obj['foo']++
++$obj['foo'];
array_pop($obj['foo']);
etc.. won't work

The fact that += works is an exception, as it's virtually $obj['foo'] =
$obj['foo'] + 1;

Description:
------------
When an element of ArrayObject is incremented (++ operation), the
object does not call its offsetSet method. I've tried overloading all
public methods in ArrayObject: offsetGet is called, but not offsetSet or
any other. Same with decrementing (--). This behaviour makes it
impossible to handle all array modifications by overloading ArrayObject
methods in derived class.

Reproduce code:
---------------
class myArray extends ArrayIterator
{
    public function offsetSet($index, $newval)
    {
        echo "offsetSet called\n";
        return parent::offsetSet($index, $newval);
    }
}

$a = new myArray(array('x' => 1));

echo "x += 1\n";
$a['x'] += 1; // calls offsetGet, then offsetSet with updated value
echo $a['x']."\n";

echo "x++\n";
$a['x']++; // only calls offsetGet
echo $a['x']."\n"; // but the value gets incremented


Expected result:
----------------
x += 1
offsetSet called
2
x++
offsetSet called
3


Actual result:
--------------
x += 1
offsetSet called
2
x++
3
