Bug #74739 [NEW]: isset() doesn't work on stdClass objects converted to arrays

From: norbert at aimeos dot com Operating system: Ubuntu PHP version: 7.0.20 Package: Scripting Engine problem Bug Type: Bug Bug description:isset() doesn't work on stdClass objects converted to arrays Description: ------------ When converting stdClass objects to arrays (e.g. from json_decode()), they look exactly like arrays when using print_r() or var_dump() but isset() or array_key_exists() doesn't work. Then testing for keys, these functions always return false. Test script: --------------- check =  new \stdClass(); $check->{"12"} = 37; $check2 = (array) $check; Expected result: ---------------- isset($check2[12]); -> true isset($check2["12"]); -> true Actual result: -------------- isset($check2[12]); -> false isset($check2["12"]); -> false -- Edit bug report at https://bugs.php.net/bug.php?id=74739&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=74739&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=74739&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=74739&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=74739&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=74739&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=74739&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=74739&r=needscript Try newer version: https://bugs.php.net/fix.php?id=74739&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=74739&r=support Expected behavior: https://bugs.php.net/fix.php?id=74739&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=74739&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=74739&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=74739&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=74739&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=74739&r=dst IIS Stability: https://bugs.php.net/fix.php?id=74739&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=74739&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=74739&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=74739&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=74739&r=mysqlcfg
