Previous Comments: ------------------------------------------------------------------------ [2010-07-11 17:56:43] ch@php.net var_dump() just showed me that the check should better be: if ($offset === null) ------------------------------------------------------------------------ [2010-07-11 17:50:52] ch@php.net Description: ------------ When implementing the ArrayAccess Interface one could be tempted to think that if "$obj[3] = $x" works, the common syntax "$obj[] = $x" would work as well. But it doesn't. For this to work one has to enhance the offsetSet() method. As it's only a one-liner I propose to put it into the example code on http://de2.php.net/manual/en/class.arrayaccess.php Expected result: ---------------- public function offsetSet($offset, $value) { if ($offset == "") $this->container[] = $value; else $this->container[$offset] = $value; } Actual result: -------------- public function offsetSet($offset, $value) { $this->container[$offset] = $value; } ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=52308&edit=1
