I'm trying to figure out the right way to take an entry from one hash
table, and put it in another, in C. This is what I first tried:
// naive attempt at
// $hash2["key"] = $hash1["key"];
zval **val;
zend_hash_find(hash1, "key", strlen("key")+1, (void **)&val);
SEPARATE_ZVAL(val);
zval_add_ref(val);
zend_hash_update(hash2, "key", strlen("key")+1, (void *)val, NULL);
That seemed to work. But I started having strange problems in my PHP
code, like I would assign the property of an object, and later the
same property would be magically null again. This problem goes away
when I remove the SEPARATE_ZVAL above.
So, I though maybe one of you kind folks might shed some light on this
for me.
Thanks,
Tim
