Description:
------------
The second time json_encode is called on objects of a given class, the
private variables of the first *instance* serialize as null.
Also, print_r produces different output after json_encode is called on
an object.
Reproduce code:
---------------
<?php
class Blah {
protected $a = array();
}
$a = new Blah; $b = new Blah;
header('Content-type: text/plain');
print ($s1 = serialize($a)) . "\n";
print "--------------------------------------------------\n";
// Comment out either of the following lines and all is well
$print_a1 = print_r($a, true);
$junk = json_encode($a);
$print_a2 = print_r($a, true);
$junk = json_encode($b); // <-- unrelated variable!!!
print ($s2 = serialize($a)) . "\n\n";
print "\n\n" . $print_a1 . "\n" . $print_a2;
?>
Expected result:
----------------
serialize() called before and after the second json_encode should
return the exact same result, given they're called on the same
unmodified variable. ($s1 and $s2 should be equal but aren't)
$print_a and $print_b should also be equal, but calling json_encode
causes print_r to mistakenly detect recursion.
Actual result:
--------------
O:4:"Blah":1:{s:4:"�*�a";a:0:{}}
--------------------------------------------------
O:4:"Blah":1:{s:4:"�*�a";N;}
Blah Object
(
[a:protected] => Array
(
)
)
Blah Object
(
[a:protected] => Array
*RECURSION*
)
