#47967 [NEW]: array_clone - would also clone referenced objects

From: r at dumb dot ro Operating system: all PHP version: 5.2.9 PHP Bug Type: *General Issues Bug description: array_clone - would also clone referenced objects Description: ------------ When you pass an array of objects to a function (not by reference) and you modfiy one of the objects in the array, the main array (the referenced objects) will be modified. This wasn't a problem until objects got passed by reference by default. Reproduce code: --------------- $class A { } $a = new A(); $a->x = 10; $arr = array($a); function foo($arr) { $arr[0]->x = 1; } foo($arr); print_r($arr); Expected result: ---------------- the expected result would be 10 Actual result: -------------- since the array is internally using references for the stored objects the result will be 1. to fix this I wrote a function that clones the array properly and I'm calling the function like this: foo(array_clone($arr)); -- Edit bug report at http://bugs.php.net/?id=47967&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=47967&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=47967&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=47967&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=47967&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=47967&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=47967&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=47967&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=47967&r=needscript Try newer version: http://bugs.php.net/fix.php?id=47967&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=47967&r=support Expected behavior: http://bugs.php.net/fix.php?id=47967&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=47967&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=47967&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=47967&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=47967&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=47967&r=dst IIS Stability: http://bugs.php.net/fix.php?id=47967&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=47967&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=47967&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=47967&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=47967&r=mysqlcfg
