used to return "" and not bool(false). It's not worth keeping it because STR_FREE() and zval_dtor() always have to check for it and it slows down the general case. In addition, it seems that empty_string has been abused quite a lot, and was used not only for setting zval's but generally in PHP code instead of "", which wasn't the intention. Last but not least, nuking empty_string should improve stability as I doubt every place correctly checked if they are not mistakenly erealloc()'ing it or calling efree() on it. NOTE: Some code is probably broken. Each extension maintainer should check and see that my changes are OK. Also, I haven't had time to touch PECL yet. Will try and do it tomorrow.
