Comment (by cadic):

 With the suggested solution, the function

 {{{#!php
 <?php
 $actual = map_deep(
         (object) array(
                 'var0'   => '1',
                 chr( 0 ) => (object) array(
                         'var0'   => '2',
                         chr( 0 ) => '3',
                 ),
                 'var1'   => (object) array(
                         'var0'   => '4',
                         chr( 0 ) => '5',
                 ),
         ),
         'intval'
 );
 }}}

 It will return an object:


 {{{
 object(stdClass) (3) {
   ["var0"]=>
   int(1)
   ["\0"]=>
   object(stdClass) (2) {
     ["var0"]=>
     string(1) "2" // <-- intval wasn't applied, parent key is \0
     ["\0"]=>
     string(1) "3" // <-- intval wasn't applied, parent key is \0
   }
   ["var1"]=>
   object(stdClass) (2) {
     ["var0"]=>
     int(4)
     ["\0"]=>
     string(1) "5" // <-- intval wasn't applied, key is \0
   }
 }
 }}}

 It's better than a Fatal error, but that also means that map_deep hasn't
 applied the callback properly to all nested properties.
