Introducing compatibility layers
- Limited support for mbstring (mb_strlen(), mb_strpos(), mb_substr() only) via iconv.
Falls back to regular strlen(), strpos(), substr() if iconv is not available.
- Password hashing, dependant on CRYPT_BLOWFISH (2y version, available since PHP 5.3.7) availability.
