Description:
------------
The SPL documentation states that if the ArrayObject::STD_PROP_LIST
flag is set on an ArrayObject instance:
"Properties of the object have their normal functionality when
accessed as list (var_dump, foreach, etc.)"
(see
http://www.php.net/~helly/php/ext/spl/classArrayObject.html#daebe26f8478746da33c266a730714a9
)
This flag does affect var_dump(), but it seems to have no impact on
foreach. See reproduce code.
I'm not sure whether this is a functional problem or a documentation
problem.
Reproduce code:
---------------
<?php
// ArrayObject::STD_PROP_LIST:
// Properties of the object have their normal functionality when
accessed as list (var_dump, foreach, etc.)
echo "Create instance of ArrayObject and add some normal
properties...\n";
$ao = new ArrayObject(array('x', 'y', 'z'),
ArrayObject::STD_PROP_LIST);
$ao->p1 = 1;
$ao->p2 = 2;
$ao->p3 = 3;
echo "\nGet property list with var_dump:\n";
var_dump($ao);
echo "\nGet property list with foreach:\n";
foreach ($ao as $key=>$value) {
echo " $key=>$value\n";
}
?>
Expected result:
----------------
Create instance of ArrayObject and add some normal properties...
Get property list with var_dump:
object(ArrayObject)#1 (3) {
["p1"]=>
int(1)
["p2"]=>
int(2)
["p3"]=>
int(3)
}
Get property list with foreach:
p1=>1
p2=>2
p3=>3
Actual result:
--------------
Create instance of ArrayObject and add some normal properties...
Get property list with var_dump:
object(ArrayObject)#1 (3) {
["p1"]=>
int(1)
["p2"]=>
int(2)
["p3"]=>
int(3)
}
Get property list with foreach:
0=>x
1=>y
2=>z
