Where does the difference come from?

Where does the difference come from?

The get_debug_handler() appears to use a slightly different output format, e.g.

object(MyIterator)#2 (1) {
  ["storage":"ArrayIterator":private]=>
  object(ArrayObject)#1 (1) {
    ["storage":"ArrayObject":private]=>
    array(3) {
      ["a"]=>
      int(1)
      ["b"]=>
      int(2)
      ["c"]=>
      int(3)
    }
  }
}

The current PR may also be incomplete or partially wrong.

PS: it was the latter.

/home/travis/build/php/php-src/ext/spl/spl_array.c: In function ‘zim_spl_Array___debugInfo’:
/home/travis/build/php/php-src/ext/spl/spl_array.c:1887:13: error: unused variable ‘ht’ [-Werror=unused-variable]

Thanks! Applied as 22a077b (and merged up, ugh).
