#48489 [Opn->Bgs]: Modifying an array member of an ArrayObject doesn't pass through offsetGet/Set

ID: 48489 Updated by: colder@php.net Reported By: angafenion at yahoo dot com -Status: Open +Status: Bogus Bug Type: SPL related Operating System: win32 PHP Version: 5.3.0RC2 New Comment: This is expected, the statement: $foo->baz['bar'] = 'far'; tries to affect the variable $foo->baz, and hence need to get it first. This is why offsetGet is called. ArrayObject::offsetGet() uses various hacks to return a reference to the initial array, allowing modifications. Previous Comments: ------------------------------------------------------------------------ [2009-06-07 08:40:52] angafenion at yahoo dot com Description: ------------ I overrode the methods of ArrayObject to normalize the keys before setting and getting members. It appears that the overridden methods are skipped when modifying an array member. Reproduce code: --------------- <?php class foo extends ArrayObject { public function __construct($data = array(), $flags = self::ARRAY_AS_PROPS, $iterator = "ArrayIterator") { parent::__construct($data, $flags, $iterator); } public function offsetSet($key, $val) { echo "offsetSet invoked\n"; parent::offsetSet($key, $val); } public function offsetGet($key) { echo "offsetGet invoked\n"; return parent::offsetGet($key); } } $foo = new foo(); $foo->baz = array(); echo count($foo->baz) . "\n"; echo "---\n"; $foo->baz['bar'] = 'foo'; echo count($foo->baz) . "\n"; Expected result: ---------------- offsetSet invoked offsetGet invoked 0 --- offsetGet invoked --[*] offsetSet invoked _/ offsetGet invoked 1 [*] actually, I'm not sure exactly what output to expect here, but at least one of these I think should appear Actual result: -------------- offsetSet invoked offsetGet invoked 0 --- offsetGet invoked 1 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=48489&edit=1
