Other Changes
PHP Core
Set(raw)cookie accepts $option Argument
setcookie() and setrawcookie() now also support the following signature:
where $options is an associative array which may have any of the keys "expires", "path", "domain", "secure", "httponly" and "samesite".New Syslog ini Directives
The following ini Directives have been added to customize logging, if error_log is set to syslog:
- syslog.facility
- Specifies what type of program is logging the message.
- syslog.filter
- Specifies the filter type to filter the logged messages. There are three supported filter types - all, no-ctrl and ascii.
- syslog.ident
- Specifies the ident string which is prepended to every message.
Garbage Collection
The cyclic GC has been enhanced, which may result in considerable performance improvements.
Miscellaneous
var_export() now exports stdClass
objects as an array cast to an object ((object) array( ... )), rather
than using the nonexistent method stdClass::__setState().
debug_zval_dump() was changed to display recursive arrays and objects in the same way as var_dump(). Now, it doesn't display them twice.
array_push() and array_unshift() can now also be called with a single argument, which is particularly convenient wrt. the spread operator.
Interactive PHP Debugger
The unused constants PHPDBG_FILE,
PHPDBG_METHOD, PHPDBG_LINENO and
PHPDBG_FUNC have been removed.
Data Filtering
FILTER_VALIDATE_FLOAT now also supports a thousand
option, which defines the set of allowed thousand separator chars. The default
("',.") is fully backward compatible with former PHP versions.
FILTER_SANITIZE_ADD_SLASHES has been added as an alias of the
magic_quotes filter (FILTER_SANITIZE_MAGIC_QUOTES).
The magic_quotes filter is subject to removal in future versions of PHP.
Internationalization Functions
Normalizer::NONE is deprecated, when PHP is linked with
ICU ≥ 56.
Introduced Normalizer::FORM_KC_CF as
Normalizer::normalize() argument for
NFKC_Casefold normalization; available when linked with
ICU ≥ 56.
JavaScript Object Notation
A new flag has been added, JSON_THROW_ON_ERROR, which
can be used with json_decode() or
json_encode() and causes these functions to throw the new
JsonException upon an error, instead of setting the
global error state that is retrieved with
json_last_error() and json_last_error_msg().
JSON_PARTIAL_OUTPUT_ON_ERROR takes precedence over
JSON_THROW_ON_ERROR.
ODBC (Unified)
Support for ODBCRouter and Birdstep including the birdstep.max_links ini directive has been removed.
OPcache
The opcache.inherited_hack ini directive has been removed. The value has already been ignored since PHP 5.3.0.
OpenSSL
The min_proto_version and max_proto_version ssl stream options as well as related constants for possible TLS protocol values have been added.
Regular Expressions (Perl-Compatible)
The PCRE extension has been upgraded to PCRE2, which may cause minor behavioral changes (for instance, character ranges in classes are now more strictly interpreted), and augments the existing regular expression syntax.
preg_quote() now also escapes the '#' character.
Microsoft SQL Server and Sybase Functions (PDO_DBLIB)
The attribute PDO::DBLIB_ATTR_SKIP_EMPTY_ROWSETS to enable automatic
skipping of empty rowsets has been added.
The PDO::DBLIB_ATTR_TDS_VERSION attribute which exposes
the TDS version has been added.
DATETIME2 columns are now treated like DATETIME columns.
SQLite Functions (PDO_SQLITE)
SQLite3 databases can now be opened in read-only mode by setting the
new PDO::SQLITE_ATTR_OPEN_FLAGS attribute to
PDO::SQLITE_READONLY.
Session Handling
session_set_cookie_params() now also supports the following signature:
where $options is an associative array which may have any of the keys "lifetime", "path", "domain", "secure", "httponly" and "samesite". Accordingly, the return value of session_get_cookie_params() now also has an element with the key "samesite". Furthermore, the new session.cookie_samesite ini option to set the default of the SameSite directive for cookies has been added. It defaults to "" (empty string), so no SameSite directive is set. Can be set to "Lax" or "Strict", which sets the respective SameSite directive.Tidy
Building against » tidyp is now also supported transparently. Since tidyp offers no API to get the release date, tidy_get_release() and tidy::getRelease() return 'unknown' in this case.
XML Parser
The return value of the xml_set_external_entity_ref_handler() callback is now also heeded if the extension has been built against libxml. Formerly, the return value has been ignored, and parsing did never stop.
Zip
Building against the bundled libzip is discouraged, but still possible by adding --without-libzip to the configuration.
Zlib Compression
The zlib/level context option for the compress.zlib wrapper to facilitate setting the desired compression level has been added.
