#33645 [NEW]: Cannot modify arrays returned by ArrayAccess::offsetGet()

From: vma1 at abv dot bg Operating system: Linux PHP version: 5.1.0b2 PHP Bug Type: Class/Object related Bug description: Cannot modify arrays returned by ArrayAccess::offsetGet() Description: ------------ It is not possible to modify an element of an array returned by ArrayAccess::offsetGet(). Also the error message suggests that offsetGet() should return a reference but it is not possible due to the offsetGet() original declaration. Reproduce code: --------------- <? class obj_array implements ArrayAccess { private $array; public function __construct ($array) { $this->array = $array; } public function offsetExists ($index) { return (array_key_exists ($index, $this->array)); } public function offsetGet ($index) { return ($this->array [$index]); } public function offsetSet ($index, $value) { $this->array [$index] = $value; } public function offsetUnset ($index) { unset ($this->array [$index]); } } $obj = new obj_array (array ("index_1" => array ("index_2" => 123))); $obj ["index_1"]["index_2"] = 456; ?> Expected result: ---------------- Nothing should be displayed when the code is run. Actual result: -------------- Fatal error: Objects used as arrays in post/pre increment/decrement must return values by reference in /archive/try.php on line 33 -- Edit bug report at http://bugs.php.net/?id=33645&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=33645&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=33645&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=33645&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=33645&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=33645&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=33645&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=33645&r=needscript Try newer version: http://bugs.php.net/fix.php?id=33645&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=33645&r=support Expected behavior: http://bugs.php.net/fix.php?id=33645&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=33645&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=33645&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=33645&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=33645&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=33645&r=dst IIS Stability: http://bugs.php.net/fix.php?id=33645&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=33645&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=33645&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=33645&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=33645&r=mysqlcfg
