Description:
------------
array_diff doesn't compare booleans.


Reproduce code:
---------------
$array1 = Array
(
    [domains] => 300
    [subdomains] => 120
    [cgi] => 
    [php] => 
    [safemode] => 1
)
$array2 = Array
(
    [domains] => 300
    [subdomains] => 120
    [cgi] => 1
    [php] => 1
    [safemode] => 
)
 

$arrayres = array_diff($array1, $array2);


Expected result:
----------------
this is a vardump of $array1, $array2 and $arrayres

array(5) {
  ["domains"]=>
  string(3) "300"
  ["subdomains"]=>
  string(3) "120"
  ["cgi"]=>
  bool(false)
  ["php"]=>
  bool(false)
  ["safemode"]=>
  bool(true)
}
array(5) {
  ["domains"]=>
  string(3) "300"
  ["subdomains"]=>
  string(3) "120"
  ["cgi"]=>
  bool(true)
  ["php"]=>
  bool(true)
  ["safemode"]=>
  bool(false)
}
array(0) {
  ["cgi"]=>
  bool(false)
  ["php"]=>
  bool(false)
  ["safemode"]=>
  bool(true)
}

Actual result:
--------------
this is a vardump of $array1, $array2 and $arrayres

array(5) {
  ["domains"]=>
  string(3) "300"
  ["subdomains"]=>
  string(3) "120"
  ["cgi"]=>
  bool(false)
  ["php"]=>
  bool(false)
  ["safemode"]=>
  bool(true)
}
array(5) {
  ["domains"]=>
  string(3) "300"
  ["subdomains"]=>
  string(3) "120"
  ["cgi"]=>
  bool(true)
  ["php"]=>
  bool(true)
  ["safemode"]=>
  bool(false)
}
array(0) {
}
