Summary: Empty string in json_decode doesn't set/reset
json_last_error
Status: Open
Type: Bug
Package: JSON related
Operating System: Linux
PHP Version: 5.3.6

Private report: N
New Comment:
a string of length 0 skips the decoder and returns null. I'm thinking it
should
set the error code to 4 so I'll fix it to do so.

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)
