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".
The following ini Directives have been added to customize logging, if
error_log is set to
syslog:
all,
no-ctrl and ascii.
The cyclic GC has been enhanced, which may result in considerable performance improvements.
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.
The unused constants PHPDBG_FILE,
PHPDBG_METHOD, PHPDBG_LINENO and
PHPDBG_FUNC have been removed.
getallheaders() 函数现已可用。
libcurl ≥ 7.15.5 is now required.
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.
The default transfer mode has been changed to binary.
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.
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.
The configuration option --with-libmbfl is no longer available.
Support for ODBCRouter and Birdstep
including the birdstep.max_links ini directive has been
removed.
The opcache.inherited_hack ini directive has been removed.
The value has already been ignored since PHP 5.3.0.
The min_proto_version and max_proto_version
ssl stream options as well as related constants for possible TLS protocol values
have been added.
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.
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.
SQLite3 databases can now be opened in read-only mode by setting the
new PDO::SQLITE_ATTR_OPEN_FLAGS attribute to
PDO::SQLITE_OPEN_READONLY.
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.
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.
The return value of the xml_set_external_entity_ref_handler() callback is no longer ignored if the extension has been built against libxml. Formerly, the return value has been ignored, and parsing did never stop.
Building against the bundled libzip is discouraged, but still possible by adding --without-libzip to the configuration.
The zlib/level context option for the compress.zlib wrapper to facilitate setting the desired compression level has been added.
