Description:
------------
the following code produces a wrong number when decoded:

$a = array('a'=>5584842151736052644);
$x = json_encode($a);
print_r(json_decode($x));

... will output stdClass Object ( [a] => 5584842151736052736 ) instead of 5584842151736052644

Test script:
---------------
$a = array('a'=>5584842151736052644);
$x = json_encode($a);
print_r(json_decode($x));

Expected result:
----------------
json_decode should output stdClass Object ( [a] => 5584842151736052644 )

Actual result:
--------------
stdClass Object ( [a] => 5584842151736052736 )

Works fine on 64-bit machines. Not much we can do about this.

That's a really old PHP. I tested your code on 5.3.x and 5.4.x and it works fine 
on 64-bit machines. I don't have a 2008 build around anywhere.
