New Comment:
these codes are weired(spl_array.c:603):
switch(Z_TYPE_P(offset)) {
case IS_STRING:
if (check_empty) {
if (zend_symtable_find(spl_array_get_hash_table(intern, 0
TSRMLS_CC), Z_STRVAL_P(offset), Z_STRLEN_P(offset)+1, (void **) &tmp) !=
FAILURE) {
switch (check_empty) {
case 0:
return Z_TYPE_PP(tmp) != IS_NULL;
case 2:
return 1;
default:
return zend_is_true(*tmp);
}
}
return 0;
} else {
return zend_symtable_exists(spl_array_get_hash_table(intern, 0
TSRMLS_CC), Z_STRVAL_P(offset), Z_STRLEN_P(offset)+1);
}
note the switch statement, there is no chance check_empty will be 0, since
there
is a if(check_empty) before.
and, I don't see any chance that the check_empty could be 2.
any idea? thanks

Description:
------------
isset(arrayobject['index']) act inconsistently with isset(array['index'])
Test script:
---------------
<?php
$a = array('b' => NULL);
var_dump(isset($a['b']));
$b = new ArrayObject($a);
var_dump(isset($b['b']));
Expected result:
----------------
bool(false)
bool(false)
Actual result:
--------------
bool(false)
bool(true)
