The type of PHP_DEBUG and PHP_ZTS constants changed to bool."," . The name of uploaded files and files created by the tempnam() function are"," now 13 bytes longer. Total length is platform-dependent."," . Encountering recursion during comparison now results in a Error exception,"," rather than a fatal error."," . Indirect modification of readonly properties within __clone() is no longer"," allowed, e.g. $ref = \u0026$this-\u003ereadonly. This was already forbidden for"," readonly initialization, and was an oversight in the \"readonly"," reinitialization during cloning\" implementation."," . The exit (and die) language constructs now behave more like a function."," They can be passed like callables, are affected by the strict_types"," declare statement, and now perform the usual type coercions instead of"," casting any non-integer value to a string."," As such, passing invalid types to exit/die may now result in a TypeError"," being thrown."," RFC: https://wiki.php.net/rfc/exit-as-function"," . The E_STRICT constant was deprecated and its corresponding error level was"," removed."," RFC: https://wiki.php.net/rfc/deprecations_php_8_4#remove_e_strict_error_level_and_deprecate_e_strict_constant","","- Extension Class constants are now typed:"," . Date"," . Intl"," . PDO"," . Reflection"," . SPL"," . Sqlite"," . XMLReader","","- Resource to Object conversions:"," Return value checks using is_resource() should be replaced with checks"," for `false`, unless specified otherwise."," . DBA:"," . dba_open() and dba_popen() will now return Dba\\Connection"," . ODBC:"," . odbc_connect() and odbc_pconnect() will now return Odbc\\Connection"," . odbc_prepare(), odbc_exec(), and various other functions will now return"," Odbc\\Result"," . SOAP:"," . SoapClient::$httpurl is now a Soap\\Url object rather than a resource."," Checks using is_resource() (i.e. is_resource($client-\u003ehttpurl)) should be"," replaced with checks for null (i.e. $client-\u003ehttpurl !== null)."," . SoapClient::$sdl is now a Soap\\Sdl object rather than a resource."," Checks using is_resource() (i.e. is_resource($client-\u003esdl)) should be"," replaced with checks for null (i.e. $client-\u003esdl !== null).","","- New warnings and exceptions:"," . Curl:"," . curl_multi_select throws a ValueError if the timeout argument if it's negative"," or greater than PHP_INT_MAX."," . GD:"," . imagejpeg/imagewebp/imagepng/imageavif throws an exception if an invalid"," quality parameter value is passed. In addition, imageavif will throw an exception"," if an invalid speed parameter value is passed."," . imagescale throws an exception if the width/height argument underflows/overflows or"," if the mode argument is invalid."," imagefilter with IMG_FILTER_SCATTER throws an exception if the sub/plus arguments"," underflows/overflows."," . Gettext:"," . bind_textdomain_codeset, textdomain and d(*)gettext functions now throw an exception"," if the domain argument is empty."," . Intl:"," . resourcebundle_get(), ResourceBundle::get(), and accessing offsets on a"," ResourceBundle object now throw:"," - TypeError for invalid offset types"," - ValueError for an empty string"," - ValueError if the integer index does not fit in a signed 32 bit integer"," . IntlDateFormatter::__construct() throws a ValueError if the locale is invalid."," . NumberFormatter::__construct() throws a ValueError if the locale is invalid."," . MBString:"," . mb_encode_numericentity() and mb_decode_numericentity() now check that"," the $map is only composed of integers, if not a ValueError is thrown."," . mb_http_input() now always throws a ValueError if the $type is invalid."," . mb_http_output() now checks that the $encoding parameter does not"," contain any null bytes. If it does, a ValueError is now thrown."," . ODBC:"," . odbc_fetch_row() now emits a warning when a value less than or equal to 0 is"," passed for parameter $row."," . PCNTL:"," . The functions pcntl_sigprocmask(), pcntl_sigwaitinfo() and"," pcntl_sigtimedwait() now throw:"," - A ValueError if the $signals array is empty (except for"," pcntl_sigprocmask() if the $mode is SIG_SETMASK)."," - A TypeError if a value of the $signals array is not an integer"," - A ValueError if a value of the $signals array is not a valid signal number"," .

The function pcntl_sigtimedwait() now throw:"," - A ValueError if $seconds is less than 0"," - A ValueError if $nanoseconds is less than 0 or greater than 1e9"," - A ValueError if both $seconds and $nanoseconds are 0"," . SimpleXML:"," . Calling simplexml_import_dom() with a non-XML object now throws a"," TypeError instead of a ValueError."," . Standard:"," . round() now validates the value of the $mode parameter and throws a"," ValueError for invalid modes. Previously invalid modes would have been"," interpreted as PHP_ROUND_HALF_UP."," . The str_getcsv() function now throws ValueErrors when the $separator and"," $enclosure arguments are not one byte long, or if the $escape is not one"," byte long or the empty string. This aligns the behaviour to be identical"," to that of fputcsv() and fgetcsv()."," . php_uname() now throws ValueErrors if the $move parameter is invalid."," . The \"allowed_classes\" option for unserialize() now throws TypeErrors and"," ValueErrors if it is not an array of class names."," . XMLReader:"," . Passing an invalid character encoding to XMLReader::open() or"," XMLReader::XML() now throws a ValueError."," . Passing a string containing null bytes previously emitted a"," warning and now throws a ValueError as well."," . XMLWriter:"," . Passing a string containing null bytes previously emitted a"," warning and now throws a ValueError as well."," . XSL:"," . XSLTProcessor::setParameter() will now throw a ValueError when its"," arguments contain null bytes. This never actually worked correctly in"," the first place, which is why it throws an exception nowadays."," . Calling XSLTProcessor::importStyleSheet() with a non-XML object now"," throws a TypeError instead of a ValueError."," . Failure to call a PHP function callback during evaluation now throws"," instead of emitting a warning."," RFC: https://wiki.php.net/rfc/improve_callbacks_dom_and_xsl","","- DOM:"," . Some DOM methods previously returned false or a PHP_ERR DOMException if a new"," node could not be allocated. They consistently throw an INVALID_STATE_ERR"," DOMException now. This situation is extremely unlikely though and probably"," will not affect you. As a result DOMImplementation::createDocument() now has"," a tentative return type of DOMDocument instead of DOMDocument|false."," . Previously, DOMXPath objects could be cloned, but resulted in an unusable"," object. This is no longer possible, and cloning a DOMXPath object now throws"," an error."," . Removed DOMImplementation::getFeature()."," RFC: https://wiki.php.net/rfc/deprecations_php_8_4#remove_domimplementationgetfeature_feature_version","","- GMP:"," . The GMP class is now final and cannot be extended anymore."," RFC: https://wiki.php.net/rfc/gmp-final","","- MBString:"," . On invalid strings (those with encoding errors), mb_substr() now interprets"," character indices in the same manner as most other mbstring functions. This"," means that character indices returned by mb_strpos() can be passed to mb_substr()."," . For SJIS-Mac (MacJapanese) strings, character indices passed to mb_substr() now"," refer to the indices of the Unicode codepoints which are produced when the string"," is converted to Unicode. This is significant because around 40 SJIS-Mac characters"," convert to a sequence of multiple Unicode codepoints.","","- Mysqli:"," . The unused and undocumented constant MYSQLI_SET_CHARSET_DIR"," has been removed."," . The MYSQLI_STMT_ATTR_PREFETCH_ROWS constant has been removed."," The feature is unavailable with mysqlnd."," . The MYSQLI_CURSOR_TYPE_FOR_UPDATE and MYSQLI_CURSOR_TYPE_SCROLLABLE"," constants have been removed. This functionality was never implemented,"," neither with mysqlnd nor with libmysql."," . The unused MYSQLI_TYPE_INTERVAL constant, which is currently a stub"," and an alias for MYSQLI_TYPE_ENUM, has been removed. There are no"," plans to add such data type to MySQL yet, so it's unclear what its value"," would finally be.","","- MySQLnd:"," . The error code reported for MySQL server wait timeouts has been changed from 2006"," to 4031 for MySQL server versions 8.0.24 and above.","","- Opcache:"," . The JIT config defaults changed from opcache.jit=tracing and"," opcache.jit_buffer_size=0 to opcache.jit=disable and"," opcache.jit_buffer_size=64M, respectively. This does not affect the default"," behavior, the JIT is still disabled by default. However, it is now disabled"," through the opcache.jit setting, rather than opcache.jit_buffer_size. This"," may affect users who previously enabled JIT through opcache.jit_buffer_size"," exclusively, without also specifying a JIT mode using opcache.jit. To enable"," JIT, set the opcache.jit config value accordingly."," . The maximum value of the opcache.interned_strings_buffer setting on 64bit"," architectures is now 32767 (it was previously 4095)."," . If JIT is enabled, PHP will now exit with a fatal error on startup in case"," of JIT startup initialization issues.","","- PCNTL:"," . The functions pcntl_sigprocmask(), pcntl_sigwaitinfo() and"," pcntl_sigtimedwait() now always return false on failure."," In some case previously it could return the value -1.","","- PCRE:"," . The bundled pcre2lib has been updated to version 10.44."," As a consequence, this means {,3} is now recognized as a quantifier instead"," of as text. Furthermore, the meaning of some character classes in UCP mode"," has changed. Consult https://github.com/PCRE2Project/pcre2/blob/master/NEWS"," for a full changelog.","","- PDO_DBLIB:"," . setAttribute, DBLIB_ATTR_STRINGIFY_UNIQUEIDENTIFIER and DBLIB_ATTR_DATETIME_CONVERT"," have been changed to set value as a bool.","","- PDO_FIREBIRD:"," . Since some Firebird C++ APIs are used now, this extension requires a C++"," compiler to be built. This also implies that the extension has to be built"," against fbclient 3.0 or higher."," . getAttribute, ATTR_AUTOCOMMIT has been changed to get the value as a bool.","","- PDO_MYSQL:"," . getAttribute, ATTR_AUTOCOMMIT, ATTR_EMULATE_PREPARES, MYSQL_ATTR_DIRECT_QUERY have"," been changed to get values as bool.","","- PDO_PGSQL:"," . The DSN's credentials, when set, are given priority over their PDO"," constructor counterparts, being closer to the documentation states.","","- SimpleXML:"," . Get methods called, or casting to a string on a SimpleXMLElement will no"," longer implicitly reset the iterator data, unless explicitly rewound."," For example, casting an element to a string within a foreach loop would"," cause an infinite loop because it destroyed the current iterator data."," This is no longer the case as a consequence of the bugfixes for GH-12192,"," GH-12208, #55098.","","- SOAP:"," . SoapClient::$typemap is now an array rather than a resource."," Checks using is_resource() (i.e. is_resource($client-\u003etypemap)) should be"," replaced with checks for null (i.e. $client-\u003etypemap !== null)."," . The SOAP extension gained an optional dependency on the session extension."," If you build PHP without the session extension and with --enable-rtld-now,"," you will experience errors on startup if you also use the SOAP extension."," To solve this, either don't use rtld-now or load the session extension.","","- Standard:"," . strcspn() with empty $characters now returns the length of the string instead"," of incorrectly stopping at the first NUL character. See GH-12592."," . http_build_query() now correctly handles backed enums."," . stream_bucket_make_writeable() and stream_bucket_new() will now return a"," StreamBucket instance instead of an instance of stdClass."," RFC: https://wiki.php.net/rfc/dedicated_stream_bucket","","- Tidy:"," . Failures in the constructor now throw exceptions rather than emitting"," warnings and having a broken object.","","- XML:"," . The xml_set_*_handler() functions now declare and check for an effective"," signature of callable|string|null for the $handler parameters."," Moreover, values of type string that correspond to method names,"," of object set with xml_set_object() are now checked to see if the method"," exists on the class of the previously passed object."," This means that xml_set_object() must now always be called prior to setting"," method names as callables."," Passing an empty string to disable the handler is still allowed,"," but deprecated.","","========================================","2. New Features","========================================","","- Core:"," . Added request_parse_body() function that allows parsing RFC1867 (multipart)"," requests in non-POST HTTP requests."," RFC: https://wiki.php.net/rfc/rfc1867-non-post"," . Getting the debug info for WeakReference will now also output the object"," it references, or null if the reference is no longer valid."," . The output of Closure::__debugInfo() now includes the name, file, and line"," of the Closure."," . new expressions with constructor arguments are now dereferencable, meaning"," they allow chaining method calls, property accesses, etc. without enclosing"," the expression in parentheses."," RFC: https://wiki.php.net/rfc/new_without_parentheses"," . Added the #[\\Deprecated] attribute."," RFC: https://wiki.php.net/rfc/deprecated_attribute"," . Implemented property hooks."," RFC: https://wiki.php.net/rfc/property-hooks"," . Exiting a namespace now clears seen symbols. This allows using a symbol in a"," namespace block, even if a previous namespace block declared a symbol with"," the same name."," See Zend/tests/use_function/ns_end_resets_seen_symbols_1.phpt."," . Implemented asymmetric property visibility."," RFC: https://wiki.php.net/rfc/asymmetric-visibility-v2"," . Implemented lazy objects."," RFC: https://wiki.php.net/rfc/lazy-objects","","- Curl:"," . curl_version() returns an additional feature_list value, which is an"," associative array of all known Curl features, and whether they are"," supported (true) or not (false)."," . Added CURL_HTTP_VERSION_3 and CURL_HTTP_VERSION_3ONLY constants (available"," since libcurl 7.66 and 7.88) as available options for CURLOPT_HTTP_VERSION."," . Added CURLOPT_PREREQFUNCTION as a Curl option that accepts a callback to"," be called after the connection is made, but before the request is sent."," The callback must return either CURL_PREREQFUNC_OK or CURL_PREREQFUNC_ABORT"," to allow or abort the request."," . Added CURLOPT_SERVER_RESPONSE_TIMEOUT, which was formerly known as"," CURLOPT_FTP_RESPONSE_TIMEOUT. Both constants hold the same value."," . Added CURLOPT_DEBUGFUNCTION support. This Curl option accepts a callable"," that gets called during the request lifetime with the CurlHandle object,"," an integer containing the debug message type, and a string containing the"," debug message. The debug message type is one of CURLINFO_TEXT, CURLINFO_HEADER_IN,"," CURLINFO_HEADER_OUT, CURLINFO_DATA_IN, CURLINFO_DATA_OUT, CURLINFO_SSL_DATA_OUT,"," CURLINFO_SSL_DATA_IN constants. Once this option is set, CURLINFO_HEADER_OUT"," must not be set because it uses the same libcurl functionality."," . curl_getinfo() function now returns \"posttransfer_time_us\", containing the"," number of microseconds from the start until the last byte is sent. When a"," redirect is followed, the time from each request is added together. This"," value can also be retrieved by passing CURLINFO_POSTTRANSFER_TIME_T to the"," curl_getinfo() $option parameter. This requires libcurl 8.10.0 or later.","","- DOM:"," . Added DOMNode::compareDocumentPosition()"," . Added constant DOMNode::DOCUMENT_POSITION_DISCONNECTED."," . Added constant DOMNode::DOCUMENT_POSITION_PRECEDING."," . Added constant DOMNode::DOCUMENT_POSITION_FOLLOWING."," . Added constant DOMNode::DOCUMENT_POSITION_CONTAINS."," .

It is now possible to pass any callable to registerPhpFunctions()."," RFC: https://wiki.php.net/rfc/improve_callbacks_dom_and_xsl","","- FPM:"," . Flushing headers without a body will now succeed. See GH-12785."," . Status page has a new field to display a memory peak.","","- Intl:"," . NumberFormatter::ROUND_HALFODD added to complement existing"," NumberFormatter::ROUND_HALFEVEN functionality.","","- OpenSSL:"," . Added support for Curve25519 + Curve448 based keys. Specifically x25519,"," ed25519, x448 and ed448 fields are supported in openssl_pkey_new and"," openssl_pkey_get_details as well as openssl_sign and openssl_verify were"," extended to support those keys."," . Implement PASSWORD_ARGON2 password hashing."," Requires OpenSSL 3.2 and NTS build.","","- PCRE:"," . The bundled pcre2lib has been updated to version 10.44."," As a consequence, LoongArch JIT support has been added, spaces"," are now allowed between braces in Perl-compatible items, and"," variable-length lookbehind assertions are now supported."," . With pcre2lib version 10.44, the maximum length of named capture groups"," has changed from 32 to 128."," . Added support for the \"r\" (PCRE2_EXTRA_CASELESS_RESTRICT) modifier, as well"," as the (?r) mode modifier. When enabled along with the case-insensitive"," modifier (\"i\"), the expression locks out mixing of ASCII and non-ASCII"," characters.","","- PDO:"," . Added support for driver-specific subclasses."," RFC: https://wiki.php.net/rfc/pdo_driver_specific_subclasses"," This RFC adds subclasses for PDO in order to better support"," database-specific functionalities. The new classes are"," instantiatable either via calling the PDO::connect() method"," or by invoking their constructor directly."," . Added support for driver specific SQL parsers. The default parser supports:"," - single and double quoted literals, with doubling as escaping mechanism."," - two-dashes and non-nested C-style comments."," RFC: https://wiki.php.net/rfc/pdo_driver_specific_parsers","","- PDO_MYSQL:"," . Added custom parser supporting:"," - single and double-quoted literals, with doubling and backslash as escaping"," mechanism"," - backtick literal identifiers and with doubling as escaping mechanism"," - two dashes followed by at least 1 whitespace, non-nested C-style comments,"," and hash-comments"," RFC: https://wiki.php.net/rfc/pdo_driver_specific_parsers","","- PDO_PGSQL:"," . Added custom parser supporting:"," - single and double quoted literals, with doubling as escaping mechanism"," - C-style \"escape\" string literals (E'string')"," - dollar-quoted string literals"," - two-dashes and C-style comments (non-nested)"," - support for \"??\" as escape sequence for the \"?\" operator"," RFC: https://wiki.php.net/rfc/pdo_driver_specific_parsers","","- PDO_SQLITE:"," . Added custom parser supporting:"," - single, double quoted, and backtick literals, with doubling as escaping mechanism"," - square brackets quoting for identifiers"," - two-dashes and C-style comments (non-nested)"," RFC: https://wiki.php.net/rfc/pdo_driver_specific_parsers","","- Phar:"," . Added support for the unix timestamp extension for zip archives.","","- Readfile:"," . Added ability to change .php_history path through PHP_HISTFILE env variable.","","- Reflection:"," .

Added support for clark notation for namespaces in class map."," It is now possible to specify entries in a class map with clark notation"," to resolve a type with a specific namespace to a specific class."," For example: '{http://example.com}foo' =\u003e 'FooClass'."," . Instances of DateTimeInterface that are passed to xsd:datetime or similar"," elements are now serialized as such instead of being serialized as an"," empty string."," . Session persistence now works with a shared session module.","","- Standard:"," . Added a new RoundingMode enum with clearer naming and improved discoverability"," compared to the PHP_ROUND_* constants."," RFC: https://wiki.php.net/rfc/correctly_name_the_rounding_mode_and_make_it_an_enum","","- XSL:"," . It is now possible to use parameters that contain both single and double"," quotes."," . It is now possible to pass any callable to registerPhpFunctions()."," RFC: https://wiki.php.net/rfc/improve_callbacks_dom_and_xsl"," .

Changes in SAPI modules","========================================","","- apache2handler"," . Support for EOL Apache 2.0 and 2.2 has been removed. Minimum required Apache"," version is now 2.4.","","- CLI:"," . The builtin server looks for an index file recursively by traversing parent"," directories in case the specified file cannot be located. This process was"," previously skipped if the path looked like it was referring to a file, i.e."," if the last path component contained a period. In that case, a 404 error was"," returned. The behavior has been changed to look for an index file in all"," cases.","","- FPM:"," . /dev/poll events.mechanism setting for Solaris/Illumos had been retired.","","========================================","4.
