This, along with the corresponding json_decode() bug of a similar nature (41504), are show stoppers for me as I need JSON encode/decode to be rock solid and consistent. Thanks for looking into this :-) Reproduce code: --------------- 1) var_dump(json_encode(array(""=>"value"))); 2) var_dump(json_encode(array(""=>"value1", "key2"=>"value2"))); Expected result: ---------------- 1) string(15) "{"":"value"}" 2) string(17) "{"":"value1", "key2":"value2"}" Actual result: -------------- 1) string(2) "{}" 2) string(17) "{"key2":"value2"}" In both cases the array entry with the empty string key is missing. This might be addressed by Bug #41034, but may very well be a different bug. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=41505&edit=1
