Bug #60905 [NEW]: It's possible to get inconsistent arrays casting stdClass object to (array)

From: Operating system: Linux PHP version: 5.3.9 Package: Scripting Engine problem Bug Type: Bug Bug description:It's possible to get inconsistent arrays casting stdClass object to (array) Description: ------------ When we cast stdClass with the numeric properties to array, we cannot access the value by key. That seems, that this bug is connected with the Bug #60379 where casting to (object) is performed. Such objects can be got by json_decode() function Test script: --------------- <? $obj = new stdClass(); $obj->{'4001'} = 'foo'; $obj->{'4002'} = 'bar'; $obj->{'4003'} = 'baz'; $arr = (array) $obj; print_r($arr); foreach($arr as $key => $val) { printf('In foreach "$key => $val" key is "%s", val is "%s" but $arr[$key] is "%s" should be "%s"', $key, $val, $arr[$key], $val); print("\n"); } Expected result: ---------------- Array ( [4001] => foo [4002] => bar [4003] => baz ) .... In foreach "$key => $val" key is "4003", val is "baz" but $arr[$key] is "baz" should be "baz" Actual result: -------------- Array ( [4001] => foo [4002] => bar [4003] => baz ) PHP Notice: Undefined index: 4001 in /home/manfred/poc.php on line 13 PHP Stack trace: PHP 1. {main}() /home/manfred/poc.php:0 In foreach "$key => $val" key is "4001", val is "foo" but $arr[$key] is "" should be "foo" PHP Notice: Undefined index: 4002 in /home/manfred/poc.php on line 13 PHP Stack trace: PHP 1. {main}() /home/manfred/poc.php:0 In foreach "$key => $val" key is "4002", val is "bar" but $arr[$key] is "" should be "bar" PHP Notice: Undefined index: 4003 in /home/manfred/poc.php on line 13 PHP Stack trace: PHP 1. {main}() /home/manfred/poc.php:0 In foreach "$key => $val" key is "4003", val is "baz" but $arr[$key] is "" should be "baz" -- Edit bug report at https://bugs.php.net/bug.php?id=60905&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=60905&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=60905&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=60905&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=60905&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=60905&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=60905&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=60905&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=60905&r=needscript Try newer version: https://bugs.php.net/fix.php?id=60905&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=60905&r=support Expected behavior: https://bugs.php.net/fix.php?id=60905&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=60905&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=60905&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=60905&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=60905&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=60905&r=dst IIS Stability: https://bugs.php.net/fix.php?id=60905&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=60905&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=60905&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=60905&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=60905&r=mysqlcfg
