Bug description:json_encode sets string to null for invalid characters
Description:
------------
When you use json_encode with an invalid UTF-8 byte sequence in a string
PHP will
generate a warning (with display_errors set to off) and the function
returns an
invalid json encoded string. The string with the invalid UTF-8 byte
sequence is
replaced with null (for example: {null:""}). This is invalid json and can
not be
decoded with json_decode.
I would think the expected behavior should be that json_encode should never
returns an invalid json encoded string. It should either return false on
failure
as the documentation states or the invalid UTF-8 byte sequence should be
handled
in a way that does not corrupt the json string.
Test script:
---------------
$key = "Foo " . chr(163);
$array = array($key => "");
var_dump($array);
$json = json_encode($array);
echo $json."\n";
var_dump(json_decode($json));
Expected result:
----------------
I would expect the returned json string to be valid or for json_encode to
return
false.
Actual result:
--------------
array(1) {
["Foo �"]=>
string(0) ""
}
{null:""}
NULL
