PHP Bug Type: Zend Engine 2 problem
Bug description: call_user_func_array allows calling of private/protected methods
Description:
------------
Using call_user_func_array you are able to call a private or protected
method of any object. I think this should not be allowed as it will lead
to bad programming style as you could use this bug to access methods which
should be hidden.
Reproduce code:
---------------
<?php
class foo {
function __construct () {
$this->bar('1');
}
private function bar ( $param ) {
echo 'Called function foo:bar('.$param.');<br>';
}
}
$foo = new foo();
call_user_func_array( array( $foo , 'bar' ) , array( '2' ) );
$foo->bar('3');
?>
Expected result:
----------------
Called function foo:bar(1);
Fatal error: Call to private method foo::bar() from context '' in
/www/htdocs/bug.php on line 14
Actual result:
--------------
Called function foo:bar(1);
Called function foo:bar(2);
Fatal error: Call to private method foo::bar() from context '' in
/www/htdocs/bug.php on line 17
