Bug description: Return by reference issue
Description:
------------
My hosting company upgraded PHP 4.3 to 4.4 a week ago and an old function
stopped working.
It returns an object by reference -- but after the changes in 4.4 it
doesn't work as expected.
Reproduce code:
---------------
class Foo {
var $bar;
}
$_array = array();
function &new_foo() {
global $_array;
$_array[] = new Foo();
return ($_array[count($_array) - 1]); // return the object at end()
}
for ($i = 0; $i < 2; $i++) {
$foo = &new_foo();
$foo->bar = 'foobar'.$i;
}
print_r($_array);
Expected result:
----------------
In PHP 4.4, change the function to this:
function &new_foo() {
$object = new Foo();
$GLOBALS['_array'][] = &$object;
return ($object);
}
The result will then be as in PHP 4.3:
Array
(
[0] => foo Object
(
[bar] => foobar0
)
[1] => foo Object
(
[bar] => foobar1
)
)
Actual result:
--------------
Array
(
[0] => foo Object
(
[bar] =>
)
[1] => foo Object
(
[bar] =>
)
)
