Bug description:  Boolean type casting print problem

Description:
------------
I think, there's a problem with type casting -- to be more specific, with
boolean casting.

When I was trying to print result of the condition (should be true, or
false) I received some unexpected output.

Reproduce code:
---------------
<?php

$b = 2;

echo 'Should be false: ' . (!$b);
echo '<br />';
echo (string) !$b;
echo '<br />';
echo (bool) !$b;
echo '<br />';
echo (int) !$b;
echo '<br />';
echo 'Should be true: ' . ((bool) $b);
echo '<br />';
var_dump(!$b);

?>

Expected result:
----------------
Should be false: false
false  // or 0?
false
0
Should be true: true
bool(false)

Actual result:
--------------
Should be false: 


0
Should be true: 1
bool(false)
