So many lines, but my question is very clear: how do I implement a write
zval property handler?
Unfortunately, I didn't find any samples in the PHP source.
Standard zend_std_write_property function does roughly the same. But my
stuff isn't working correctly.

Hi,
I have a mixed read-write property here:

The property write handler

calls php_ev_prop_write_zval.
static inline void php_ev_prop_write_zval(zval **ppz, zval *value)
{
if (!*ppz) {
MAKE_STD_ZVAL(*ppz);
}
REPLACE_ZVAL_VALUE(ppz, value, 1);
}
Should I call REPLACE_ZVAL_VALUE with or without "copy"(1)? I suspect it
should be 0.
Let's look at some PHP code. The following script outputs "123".
```
<?php
class indicator {
public function __destruct() {
echo "2";
}
}
class A {
public $data;
}
function test() {
$a = new A();
$indicator = new indicator();
$a->data = $indicator;
debug_zval_dump($indicator);
debug_zval_dump($a);
$indicator = null;
echo "1";
$a = null;
echo "3";
}
test();
echo "\n";
```
But the code below outputs:
13
2
However, when I change the last argument of REPLACE_ZVAL_VALUE to zero,
both scripts output the same "123" string.
So should I call `REPLACE_ZVAL_VALUE(ppz, value, 0);` instead?
