Summary: json_decode handles whitespace and case-sensitivity
incorrectly
Status: Open
Type: Bug
Package: JSON related
Operating System: All
PHP Version: 5.4.15
Block user comment: N
Private report: N
New Comment:
RFC 4627[1] also states in section 2:
| A JSON text is a serialized object or array.
|
| JSON-text = object / array
According to that definition the $json argument of examples 1-3
is not a valid JSON-text.
Furthermore:
json_decode('true ');
var_dump(json_last_error() === JSON_ERROR_SYNTAX);
prints:
bool(true)
So the returned NULL is actually correct according to the documentation.

Description:
------------
There are 2 problems with the json_decode function.
1) It only sometimes disregards whitespace
The RFC clearly says:
"""Insignificant whitespace is allowed before or after any of the six
structural
characters."""
2) It only sometimes enforces lowercase-ness of identifiers
The RFC clearly says:
"""The literal names MUST be lowercase. No other literal names are allowed."""
The test script demonstrates this
Test script:
---------------
<?
function json_cmp($x, $y)
{
print var_dump(json_decode($x) === $y);
}
// works
json_cmp("true", true);
// fails - is actually true
json_cmp("tRue", NULL);
// fails - is actually NULL
json_cmp("true ", true);
// works
json_cmp("[true ] ", array(true));
// works, even though the non-array version fails
json_cmp("[tRue]", NULL);
?>
Expected result:
----------------
true * 5
Actual result:
--------------
bool(true)
bool(false)
bool(false)
bool(true)
bool(true)
