Use get_object_vars() instead. Previous Comments: ------------------------------------------------------------------------ [2017-06-10 13:49:16] norbert at aimeos dot com 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 this bug report at https://bugs.php.net/bug.php?id=74739&edit=1
