From:
Operating system: Windows 7 x64
PHP version: Irrelevant
Package: Scripting Engine problem
Bug Type: Bug
Bug description:Function arguments can only be changed when native values are
given.
Description:
------------
The problem with debug_backtrace() is, that only function parameter values
which are native types can be changed, but not if the value is an object.
Test script:
---------------
<?php
function errorHandler($level, $msg){
$debug = debug_backtrace();
$debug[1]['args'][0]='1';
return true;
}
set_error_handler('error');
function a($a){ // E_RECOVERABLE_ERROR
var_dump($a);
}
class A{}
a(1);
a(2);
a(new A());
?>
Expected result:
----------------
int 1
int 1
int 1
Actual result:
--------------
int 1
int 1
object A
