Backward Incompatible Changes ======================================== -- Core: - . gettype() will now return "resource (closed)" instead of "unknown type" for - closed resources. - . is_object() will now return true for objects of class - __PHP_Incomplete_Class. - . Support for Netware operating systems have been removed. - . Casting arrays to objects (with (object) or settype()) will now covert - integer keys to string property names. This fixes the behaviour of previous - versions, where integer keys would become inaccessible properties with - integer names. - . Casting objects to arrays (with (array) or settype()), and retrieving - object properties in an array with get_object_vars(), will now convert - numeric string property names (that is, property names of the format - /^(0|(-?[1-9][0-9]*))$/ where PHP_INT_MIN <= n <= PHP_INT_MAX) to integer - keys. This fixes the behaviour of previous versions, where numeric string - property names would become inaccessible string keys. - . Unqualified references to undefined constants now generate a Warning instead - of a notice. They will generate an Error in a future version of PHP. - (https://wiki.php.net/rfc/deprecate-bareword-strings) - . Minimum supported Windows versions are Windows 7/Server 2008 R2. - . Initial trait property value compatibility check will no longer perform - any casts. (Bug #74269) - . "object" (in any case) can no longer be used as a class name. - -- BCMath: - . The bcmod() function no longer truncates fractional numbers to integers. As - such, its behavior now follows fmod() rather than the `%` operator. For - example `bcmod('4', '3.5')` now returns '0.5' instead of '1'. - -- Hash: - . The hash_hmac(), hash_hmac_file(), hash_pbkdf2() and hash_init() (with - HASH_HMAC) functions no longer accept non-cryptographic hashes. - -- JSON - . The json_decode() option JSON_OBJECT_AS_ARRAY is used if the second - parameter (assoc) is null. Previously JSON_OBJECT_AS_ARRAY was always - ignored. - -- Session: - . Removed register_globals related code and "!" can be used as $_SESSION key name. - . Session is made to manage session status correctly and prevents invalid operations. - Only inappropriate codes are affected by this change. If you have problems with this, - it means you have problem in your code. - . Functions are made to set or return correct session status. - session_start(), session_status(), session_regenerate_id() - . Functions are made to return bool from null. These functions have void parameter - and void parameter is checked. - session_unset(), session_write_close()/session_commit(), session_abort(), - session_reset() - . Functions prohibit invalid operations with regard to session status and - HTTP header status, returns correct bool return value. - session_start(), session_set_cookie_params(), session_name(), session_module_name(), - session_set_save_handler(), session_regenerate_id(), session_cache_limiter(), - session_cache_expire(), session_unset(), session_destroy(), - session_write_close()/session_commit(), session_reset() - . INI value change by ini_set() returns update status correctly. Invalid INI modifications - are checked and made to fail. - session.name, session.save_path, session.cookie_lifetime, session.cookie_path, - session.cookie_domain, session.cookie_httponly, session.cookie_secure, - session.use_cookies, session.use_only_cookies, session.use_strict_mode, - session.referer_check, session.cache_limiter, session.cache_expire, - session.lazy_write, session.save_handler, session.serialize_handler, - session.gc_probability, session.gc_divior, session.gc_maxlifetime, - . Some E_ERRORs are changed to E_WARNING since session status is managed correctly. - session_start() - . Session no longer initialize $_SESSION for invalid and useless session. - session_start() - . When headers are already sent and try to set new INI values, session_name(), - session_module_name(), session_save_path(), session_cache_limiter() and - session_cache_expire() are no longer works. Older PHPs accepts new values even - if new values will not be effective. - This new corrected behavior may affect command line mode CLI scripts that manage - sessions. Use output buffer just like web applications to resolve problems on - CLI scripts. - - ======================================== 2. New Features ======================================== -- Core: - . It is now possible to remove argument type annotations when overriding an - inherited method. This complies with contravariance of method argument types - under the Liskov Substitution Principle. - (https://wiki.php.net/rfc/parameter-no-type-variance) - . It is now allowed to override an abstract method with another abstract - method in a child class. - (https://wiki.php.net/rfc/allow-abstract-function-override) - . A trailing comma in group use statements is now allowed. - (https://wiki.php.net/rfc/list-syntax-trailing-commas) - .

Added Oracle Database Transparent Application Failover (TAF) callback support. - -- PCRE: - . Added `J` modifier for setting PCRE_DUPNAMES. - .

New cryptographic extension - -- SQLite3: - . Implemented writing to BLOBs. - -- Standard: - . Simplified password hashing API updated to support Argon2i hashes when PHP is compiled with libargon2 - (https://wiki.php.net/rfc/argon2_password_hash). - . proc_nice() is now supported on Windows platforms. - -- Zip: - . read/write encrypted archive, relying on libzip 1.2.0, - using new methods: - ZipArchive::setEncryptionName($name, $method [, $password]); - ZipArchive::setEncryptionIndex($index, $method [, $password]); - and new constants: - ZipArchive::EM_NONE - ZipArchive::EM_AES_128 - ZipArchive::EM_AES_192 - ZipArchive::EM_AES_256 - . accept 'password' from zip stream context - . ZipArchive implements countable, added ZipArchive::count() method. - - ======================================== 3.
