From: auroraeosrose at hotmail dot com Operating system: irrelevant PHP version: 5CVS-2005-03-17 (dev) PHP Bug Type: Feature/Change Request Bug description: Match overloading behavior to ArrayAccess behavior
Description: ------------ when implementing the ArrayAccess (spl stuff) interface you can create a offsetExists() which hooks into calling isset on your object e.g. isset($object[offset]) (by the way, I love you marcus) but when using __get and __set with objects, isset becomes absolutely useless and there is no way to tell what you've set with __set, and it's annoying to do something like returning NULL from __get and then doing is_nulls everywhere Please please please please can we get an __isset hook somehow - spl, overloading, something??? I've read the whole argument (http://bugs.php.net/bug.php?id=29917) about how __isset would have to be called for every property, well can it be hooked so it would only be called for public or properties that regular isset shoots back false? this is a major pain in the butt, I'd take the slowdown for the functionality any day Reproduce code: --------------- class data implements ArrayAccess { protected $array; public function __construct(&$array) { $this->array =& $array; return; } public function __get($offset) { return $this->offsetGet($offset); } public function __set($offset, $value) { return $this->offsetSet($offset, $value); } public function offsetExists($offset) { return isset($this->array[$offset]); } public function offsetGet($offset) { if(isset($this->array[$offset])) { return $this->array[$offset]; } return; } public function offsetSet($offset, $value) { $this->array[$offset] = $value; return; } public function offsetUnset($offset) { if(isset($this->array[$offset])) { unset($this->array[$offset]); } return; } } $array = array('one' => 1, 'two' => 2, 'three' => 3, 'four' => 4); $class = new data($array); var_dump(isset($class['one'])); var_dump(isset($class->one)); Expected result: ---------------- bool(true) bool(true) Actual result: -------------- bool(true) bool(false) -- Edit bug report at http://bugs.php.net/?id=32347&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=32347&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=32347&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=32347&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=32347&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=32347&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=32347&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=32347&r=needscript Try newer version: http://bugs.php.net/fix.php?id=32347&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=32347&r=support Expected behavior: http://bugs.php.net/fix.php?id=32347&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=32347&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=32347&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=32347&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=32347&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=32347&r=dst IIS Stability: http://bugs.php.net/fix.php?id=32347&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=32347&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=32347&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=32347&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=32347&r=mysqlcfg
