Bug description:Empty string in json_decode doesn't set/reset json_last_error
Description:
------------
If you decode an empty json value, the internal error state doesn't
change.
Decode a valid json value and after that an empty value, the error state is
0
Decode an invalid json value and after that an empty value, the error state
remains 4 (JSON_ERROR_SYNTAX) (I think it's the same for all error states,
but haven't actually tested)
I'm not quite sure whether an empty string is valid json and should reset
the error state to 0 or whether it is invalid json and should set the error
state to 4. Because a valid empty json string is '""' and not ''
Test script:
---------------
<?php
error_reporting(E_ALL);
json_decode('{"test":"test"}');
var_dump(json_last_error());
json_decode("");
var_dump(json_last_error());
json_decode("invalid json");
var_dump(json_last_error());
json_decode("");
var_dump(json_last_error());
?>
Expected result:
----------------
int(0)
int(0)
int(4)
int(0)
OR
int(0)
int(4)
int(4)
int(4)
Actual result:
--------------
int(0)
int(0)
int(4)
int(4)
