New Comment:
Well, if PHP5 were stable, I wouldn't care, but...for now, it's very
annoying.
Just a quick note for those having this problem. First, easiest way to
fix it us to turn off overloading (for DB_DataObject, for instance, use
define('DB_DATAOBJECT_NO_OVERLOAD', 0);
For those who can't turn off overloading, use call-time
pass-by-reference. Yes, it's deprecated, but it fixes the problem.
$obj->function(&$paramByRef);

And it will stay as such with PHP 4.

This is also an issue with php 4.3.3RC4, but not with 5.0.0b1

Description:
------------
When a class which is overloaded is included in another php file via
'require_once', 'require', etc., functions in classes which inherit
from that class and that take references no longer seem to be getting
references, rather they seem to be getting copies of the argument
variables.
Here's my setup (from 'phpinfo()'):

Incidently, in my example code php doesn't complain if
'my_base_b::my_base_b()' is not defined, but it does give an error if
'my_base_a::my_base_a()' isn't defined. From what I read in the manual,
it should complain because __call applies to constructors as well.
Reproduce code:
---------------
test_inc.php:
=================
<?php
class my_base_a {
function my_base_a( ) { }
function __call( $method, $params, &$return ) {
return( false );
}
};
overload("my_base_a");
?>
test_main.php:
=================
<?php
require_once('test_inc.php');
class my_base_b {
function my_base_b( ) { }
function __call( $method, $params, &$return ) {
return( false );
}
};
overload("my_base_b");
class overload_a extends my_base_a {
function modify_reference( &$ref ) {
$ref = "Modified Reference";
}
};
class overload_b extends my_base_b {
function modify_reference( &$ref ) {
$ref = "Modified Reference";
}
}
$instance_a = new overload_a( );
$instance_b = new overload_b( );
$ref_a = $ref_b = "Unmodified Reference";
print "Before: $ref_a, $ref_b<br>";
$instance_a->modify_reference( $ref_a );
$instance_b->modify_reference( $ref_b );
print "After: $ref_a, $ref_b<br>";
?>
Expected result:
----------------
Before: Unmodified Reference, Unmodified Reference
After: Modified Reference, Modified Reference
Actual result:
--------------
Before: Unmodified Reference, Unmodified Reference
After: Unmodified Reference, Modified Reference
