hmm, yes, subclass still use that write_func.
a solution might be use composite, like:
class MysqliMock {
public $mysqli;
public function __construct() {
$this->mysqli = new MySQLi();
}
public function __call($method, $args) {
call_user_func_array(array($this->mysqli, "method"), $args)
}
public function __get($name) {
//you can mock the properties here
}
public function __set($name, $value) {
}
}
?>
what do you think? thanks

I understand that making the properties (not only affected_rows) readonly
ensures certain integrity. No arguing there.
What I'm trying to do is mock the MySQLi class (and some others) for unit
testing. Mocking the methods works fine, but the properties have been a bit of
a
difficulty. My solution so far was to hook in behind MySQLi and mock the actual
database connection using mysqlnd_uh. But that is not working (yet) with 5.4
and
no real estimations of when that will be fixed. With 5.5 drawing nearer, I was
looking at alternative ways to do this. I tried subclassing MySQLi as well,
that
didn't work either.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php
mysqli link properties are designed to be read-only.
the write func for them throw that error:
static int mysqli_write_na(mysqli_object *obj, zval *newval TSRMLS_DC)
{
php_error_docref(NULL TSRMLS_CC, E_ERROR, "Cannot write property");
return FAILURE;
}

affected_rows property is kinda readonly property, so we can't change
that with reflection apis or property value update.
it makes the property reliable, I don't see a reason to change that,
I you really need to do that inherit it with a subclass.

Description:
------------
It doesn't seem to be possible to get write access to properties of mysqli
classes
using the Reflection API.
Test script:
---------------
$mysqli = new MySQLi();
$reflection = new ReflectionClass('\MySQLi');
$property = $reflection->getProperty('affected_rows');
$property->setAccessible(TRUE);
$property->setValue($mysqli, 10);
Expected result:
----------------
No Error
Actual result:
--------------
Fatal error: ReflectionProperty::setValue(): Cannot write property
------------------------------------------------------------------------
