## #6331 — Simeon Koptelov — 2003-12-10T04:21:49+00:00

Hello internals,

  I'm writing extension that substitutes object's read_property
  and write_property handlers with it's own and I found that such code

  <?php
  
  class A
  {
        private $arr = array();

        public function addToArr( $element )
        {
               $this->arr[] = $element;
        }
  }

  $a = new A();
  $something = new A();
  $a->addToArr( $something );

  ?>

  doesn't produce call to read_property or write_property. It seems
  strange because something like

  count( $this->arr )
  or
  foreach( $this->arr as $element )

  from A does produce call to read_property for "arr".
  Is it a bug or feature? If it's the expected behaviour, how can I
  intercept modification of array-type property?
