========================================
1. Backward Incompatible Changes
========================================
Core:
. The ext_skel utility has been completely redesigned with new options and
some old options removed. This is now written in PHP and has no external
dependencies.
. Support for BeOS has been dropped.
. Exceptions thrown due to automatic conversion of warnings into exceptions
in EH_THROW mode (e.g. some DateTime exceptions) no longer populate
error_get_last() state. As such, they now work the same way as manually
thrown exceptions.
. TypeError now reports wrong types as `int` and `bool` instead of `integer`
and `boolean`.
. Due to the introduction of flexible heredoc/nowdoc syntax (see New Features
section), doc strings that contain the ending label inside their body may
cause syntax errors or change in interpretation. For example in
$str = <<<FOO
abcdefg
FOO
FOO;
the indented occurrence of "FOO" did not previously have any special
meaning. Now it will be interpreted as the end of the heredoc string and
the following "FOO;" will cause a syntax error. This issue can always be
resolved by choosing an ending label that does not occur within the contents
of the string.
. "continue" statements targeting "switch" control flow structures will now
generate a warning. In PHP such "continue" statements are equivalent to
"break", while they behave as "continue 2" in other languages.
while ($foo) {
switch ($bar) {
case "baz":
continue;
// Warning: "continue" targeting switch is equivalent to
// "break". Did you mean to use "continue 2"?
}
}
. Array accesses of type $obj["123"], where $obj implements ArrayAccess and
"123" is an integer string literal will no longer result in an implicit
conversion to integer, i.e., $obj->offsetGet("123") will be called instead
of $obj->offsetGet(123). This matches existing behavior for non-literals.
The behavior of arrays is not affected in any way, they continue to
implicitly convert integeral string keys to integers.
. In PHP, static properties are shared between inheriting classes, unless the
static property is explicitly overridden in a child class. However, due to
an implementation artifact it was possible to separate the static properties
by assigning a reference. This loophole has been fixed.
class Test {
public static $x = 0;
}
class Test2 extends Test { }
Test2::$x = &$x;
$x = 1;
var_dump(Test::$x, Test2::$x);
// Previously: int(0), int(1)
// Now: int(1), int(1)
. References returned by array and property accesses are now unwrapped as
part of the access. This means that it is no longer possible to modify the
reference between the access and the use of the accessed value:
$arr = [1];
$ref =& $arr[0];
var_dump($arr[0] + ($arr[0] = 2));
// Previously: int(4), Now: int(3)
This makes the behavior of references and non-references consistent. Please
note that reading and writing a value inside a single expression remains
undefined behavior and may change again in the future.
. Argument unpacking stopped working with Traversables with non-integer keys.
The following code worked in PHP 7.0-7.2 by accident.
function foo(...$args) {
var_dump($args);
}
function gen() {
yield 1.23 => 123;
}
foo(...gen());
Now it generates an exception.
BCMath:
. All warnings thrown by BCMath functions are now using PHP's error handling.
Formerly some warnings have directly been written to stderr.
. bcmul() and bcpow() now return numbers with the requested scale. Formerly,
the returned numbers may have omitted trailing decimal zeroes.
DOM:
. As of PHP 7.3.16, the value of the $childNodes property of DOMDocument,
DOMNode, DOMProcessingInstruction, DOMComment, DOMText, DOMCdataSection and
DOMNotation is now an empty DOMNodeList instead of NULL, according to the
W3C and WHATWG standards and the PHP manual.
IMAP:
rsh/ssh logins are disabled by default. Use imap.enable_insecure_rsh if you want
to enable them. Note that the IMAP library does not filter mailbox names before
passing them to rsh/ssh command, thus passing untrusted data to this function
with rsh/ssh enabled is insecure.
MBString:
. Due to added support for named captures, mb_ereg_*() patterns using named
captures will behave differently. In particular named captures will be part
of matches and mb_ereg_replace() will interpret additional syntax. See
"New Features" section for more information.
mysqli:
. Prepared statements now properly report the fractional seconds for DATETIME/
TIME/TIMESTAMP columns with decimals specifier (e.g. TIMESTAMP(6) when using
microseconds). Formerly, the fractional seconds part was simply omitted from
the returned values.
PDO/MySQL:
. Prepared statements now properly report the fractional seconds for DATETIME/
TIME/TIMESTAMP columns with decimals specifier (e.g. TIMESTAMP(6) when using
microseconds). Formerly, the fractional seconds part was simply omitted from
the returned values.
Please note that this only affects the usage of PDO_MYSQL with emulated
prepares turned off (e.g. using the native preparation functionality).
Statements using connections having PDO::ATTR_EMULATE_PREPARES=true (which
is the default) were not affected by the bug fixed and have already been
getting the proper fractional seconds values from the engine.
Reflection:
. Reflection export to string now uses `int` and `bool` instead of `integer`
and `boolean`.
SPL:
. If an SPL autoloader throws an exception, following autoloaders will not be
executed. Previously all autoloaders were executed and exceptions were
chained.
SimpleXML:
. Mathematic operations involving SimpleXML objects will now treat the text as
an integer or float, whichever is more appropriate. Previously values were
treated as integers unconditionally.
Standard:
. Undefined variables passed to compact() will now be reported as a notice.
. getimagesize() and related functions now report the mime type of BMP images
as image/bmp instead of image/x-ms-bmp, since the former has been registered
with the IANA (see RFC 7903).
. stream_socket_get_name() will now return IPv6 addresses wrapped in brackets.
For example "[::1]:1337" will be returned instead of "::1:1337".
========================================
2. New Features
========================================
Core:
. Implemented flexible heredoc and nowdoc syntax: The closing marker for doc
strings is no longer required to be followed by a semicolon or newline.
Additionally the closing marker may be indented, in which case the
indentation will be stripped from all lines in the doc string.
(RFC: https://wiki.php.net/rfc/flexible_heredoc_nowdoc_syntaxes)
. Array destructuring now supports reference assignments using the syntax
[&$a, [$b, &$c]] = $d. The same is also supported for list().
(RFC: https://wiki.php.net/rfc/list_reference_assignment)
. instanceof now allows literals as the first operand,
in which case the result is always FALSE.
. A new CompileError exception has been added, from which ParseError inherits.
A small number of compilation errors will now throw a CompileError instead
of generating a fatal error. Currently this only affects compilation errors
that may be thrown by token_get_all() in TOKEN_PARSE mode, but more errors
may be converted in the future.
. Trailing commas in function and method calls are now allowed.
(RFC: https://wiki.php.net/rfc/trailing-comma-function-calls)
BCMath:
. bcscale() can now also be used as getter to retrieve the current scale in use.
MBString:
. Support for full case-mapping and case-folding has been added. Unlike simple
case-mapping, full case-mapping may change the length of the string. For
example:
mb_strtoupper("Straße")
// Produces STRAßE on PHP 7.2
// Produces STRASSE on PHP 7.3
The different casing mapping and folding modes are available through
mb_convert_case():
. MB_CASE_LOWER (used by mb_strtolower)
. MB_CASE_UPPER (used by mb_strtoupper)
. MB_CASE_TITLE
. MB_CASE_FOLD
. MB_CASE_LOWER_SIMPLE
. MB_CASE_UPPER_SIMPLE
. MB_CASE_TITLE_SIMPLE
. MB_CASE_FOLD_SIMPLE (used by case-insensitive operations)
Only unconditional, language agnostic full case-mapping is performed.
. Case-insensitive string operations now use case-folding instead of case-
mapping during comparisons. This means that more characters will be
considered (case insensitively) equal now.
. mb_convert_case() with MB_CASE_TITLE now performs title-case conversion
based on the Cased and CaseIgnorable derived Unicode properties. In
particular this also improves handling of quotes and apostophes.
. Data tables have been updated for Unicode 11.
. Mbstring now correctly supports strings larger than 2GB.
. Performance of the mbstring extension has been significantly improved
across the board. The largest improvements are in case conversion functions.
. mb_ereg_*() functions now support named captures. Matching functions like
mb_ereg() will now return named captures both using their group number and
their name, similar to PCRE:
mb_ereg('(?<word>\w+)', '国', $matches);
// => [0 => "国", 1 => "国", "word" => "国"];
Additionally, mb_ereg_replace() now supports the \k<> and \k'' notations
to reference named captures in the replacement string:
mb_ereg_replace('\s*(?<word>\w+)\s*', "_\k<word>_\k'word'_", ' foo ');
// => "_foo_foo_"
\k<> and \k'' can also be used for numbered references, which also works
with group numbers greater than 9.
readline:
. Support for the completion_append_character and completion_suppress_append
options has been added to readline_info(). These options are only available
if PHP is linked against libreadline (rather than libedit).
Standard:
. The --with-password-argon2[=dir] configure argument now provides support for
both Argon2i and Argon2id hashes in the password_hash(), password_verify(),
password_get_info(), and password_needs_rehash() functions. Passwords may be
hashed and verified using the PASSWORD_ARGON2ID constant.
Support for both Argon2i and Argon2id in the password_* functions now requires
PHP be linked against libargon2 reference library >= 20161029.
(RFC: https://wiki.php.net/rfc/argon2_password_hash_enhancements).
LDAP:
. Full support for LDAP Controls has been added to LDAP querying functions
and ldap_parse_result
========================================
3. Changes in SAPI modules
========================================
phpdbg:
. The unused constants PHPDBG_FILE, PHPDBG_METHOD, PHPDBG_LINENO and
PHPDBG_FUNC have been removed.
FPM:
. A new global option log_limit has been added. It can be used for setting
log limit for logged line which allows to log messages longer than 1024
characters without wrapping. It also fixes various wrapping issues.
. A new global option log_buffering has been added. It allows an experimental
logging without extra buffering.
. A new pool option decorate_workers_output has been added. It allows
disabling output decoration for workers output when catch_workers_output
enabled.
. The getallheaders() function is now also available.
. In PHP 7.3.11 a new pool option
request_terminate_timeout_track_finished has been added. When enabled,
request_terminate_timeout will also apply after fastcgi_finish_request()
has been called, as well as during execution of shutdown functions.
========================================
4. Deprecated Functionality
========================================
Core:
. The declaration of case-insensitive constants has been deprecated. Passing
true as the third argument to define() will now generate a deprecation
warning. The use of case-insensitive constants with a case that differs from
the declaration is also deprecated.
(RFC: https://wiki.php.net/rfc/case_insensitive_constant_deprecation)
. Declaring a function called assert() inside a namespace is deprecated.
The assert() function is subject to special handling by the engine, which
may lead to inconsistent behavior when defining a namespaced function with
the same name.
Filter:
. The explicit usage of the constants FILTER_FLAG_SCHEME_REQUIRED and
FILTER_FLAG_HOST_REQUIRED is now deprecated; both are implied for
FILTER_VALIDATE_URL anyway.
GD:
. image2wbmp() has been deprecated.
Intl:
. Usage of the Normalizer::NONE form throws a deprecation warning, if PHP is
linked with ICU >= 56.
Mbstring:
. The following undocumented mbereg_*() aliases have been deprecated. Use the
corresponding mb_ereg_*() variants instead.
. mbregex_encoding()
. mbereg()
. mberegi()
. mbereg_replace()
. mberegi_replace()
. mbsplit()
. mbereg_match()
. mbereg_search()
. mbereg_search_pos()
. mbereg_search_regs()
. mbereg_search_init()
. mbereg_search_getregs()
. mbereg_search_getpos()
. mbereg_search_setpos()
PDO ODBC:
. The pdo_odbc.db2_instance_name ini setting has been formally deprecated. It
has already been deprecated in the documentation since PHP 5.1.1.
Standard:
. Passing a non-string needle to string search functions is deprecated. In the
future the needle will be interpreted as a string instead of an ASCII codepoint.
Depending on the intended behavior, you should either explicitly cast the
needle to string or perform an explicit call to chr(). The following functions
are affected:
. strpos()
. strrpos()
. stripos()
. strripos()
. strstr()
. strchr()
. strrchr()
. stristr()
. The fgetss() function and the string.strip_tags stream filter have been deprecated.
This also affects the SplFileObject::fgetss() method and gzgetss() function.
========================================
5. Changed Functions
========================================
JSON:
. 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 a
JsonException upon an error, instead of setting the global error state that
is retrieved with json_last_error(). JSON_PARTIAL_OUTPUT_ON_ERROR takes
precedence over JSON_THROW_ON_ERROR.
(RFC: https://wiki.php.net/rfc/json_throw_on_error)
Session:
. session_set_cookie_params() now also supports the following signature:
session_set_cookie_params(array $options)
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".
Standard:
. 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.
. setcookie() and setrawcookie() now also support the following signature:
set(raw)cookie(string $name, [string $value, [array $options]])
where $options is an associative array which may have any of the keys
"expires", "path", "domain", "secure", "httponly" and "samesite".
PCRE:
. preg_quote() now also escapes the '#' character.
LDAP:
. Added a serverctrls parameter to send controls to the server in ldap_add,
ldap_mod_replace, ldap_mod_add, ldap_mod_del, ldap_rename,
ldap_compare, ldap_delete, ldap_modify_batch,
ldap_search, ldap_list, ldap_read
. Added an out parameter to get controls from the server in ldap_parse_result
. Fixed support for LDAP_OPT_SERVER_CONTROLS and LDAP_OPT_CLIENT_CONTROLS in
ldap_get_option and ldap_set_option.
========================================
6. New Functions
========================================
Core:
. Added monotonic timer function hrtime([bool get_as_num]). It returns an
array of the form [seconds, nanoseconds] with the timestamp starting at
an unspecified point in the past. If the optional argument is passed as
true, the return value is an integer on 64-bit systems or float on
32-bit systems, representing the nanoseconds. The timestamp is not
adjustable and is not related to wall clock or time of day. The timers
are available under Linux, FreeBSD, Windows, Mac, SunOS, AIX and their
derivatives. If no required timers are provided by a corresponding
platform, the function returns false.
. Added net_get_interfaces() to retrieve an array of available network
interfaces including several details.
. Added the gc_status() function to retrieve status information regarding the
cyclic GC.
Date:
. Added the DateTime::createFromImmutable() method, which mirrors
DateTimeImmutable::createFromMutable().
FPM:
. Added fpm_get_status() function which returns FPM status info array.
GMP:
. Added gmp_binomial(n, k) for calculating binomial coefficients.
. Added gmp_lcm(a, b) for calculating the least common multiple.
. Added gmp_perfect_power(a) to check if number is a perfect power.
. Added gmp_kronecker(a, b) to compute the Kronecker symbol.
Intl:
. Added void Spoofchecker::setRestrictionLevel(int $level) method, available
when linked with ICU >= 58.1. Levels are represented as class constants
- Spoofchecker::ASCII
- Spoofchecker::HIGHLY_RESTRICTIVE
- Spoofchecker::MODERATELY_RESTRICTIVE
- Spoofchecker::MINIMALLY_RESTRICTIVE
- Spoofchecker::UNRESTRICTIVE
- Spoofchecker::SINGLE_SCRIPT_RESTRICTIVE
For the detailed documentation on the restriction levels, see
URestrictionLevel under
http://icu-project.org/apiref/icu4c/uspoof_8h.html
. Added Normalizer::getRawDecomposition() and normalizer_get_raw_decomposition(),
to retrieve the Decomposition_Mapping property of a character.
LDAP:
. Added ldap_exop_refresh() to conveniently perform a Refresh extended
operation.
OpenSSL:
. Added openssl_pkey_derive that derives a shared secret for DH, ECDH and
possibly other future algorithms supported by EVP_PKEY_derive.
Sockets:
. Added functions to import/export the WSAPROTOCOL_INFO info struct. This
implementation complements the already supported SCM_RIGHTS as in
man 3 cmsg and is Windows specific. For the import/export, the default
system securities apply for the SHM reading/writing. The socket becomes
invalid, when the last reference to it is closed.
- socket_wsaprotocol_info_export(resource $sock, int $pid) - exports the
WSAPROTOCOL_INFO structure into shared memory and returns an identifier
to be used for the import, or false on failure. The exported ID is
only valid for the dedicated PID.
- socket_wsaprotocol_info_import(string $id) - returns a duplicated
socket as per the passed identifier, or false on failure.
- socket_wsaprotocol_info_release(string $id) - releases the shared memory
corresponding to the passed identifier.
Standard:
. Added is_countable() function, to check whether a value may be passed to
count().
(RFC: https://wiki.php.net/rfc/is-countable)
. Added array_key_first() and array_key_last() which retrieve the first and
last key of an array, respectively.
(RFC: <https://wiki.php.net/rfc/array_key_first_last>)
LDAP:
. Added functions ldap_add_ext, ldap_bind_ext, ldap_delete_ext, ldap_mod_add_ext,
ldap_mod_replace_ext, ldap_mod_del_ext, ldap_rename_ext
which gives access to the result object to be able to parse it
with ldap_parse_result and get more information than just success/failure.
========================================
7. New Classes and Interfaces
========================================
JSON:
. JsonException
========================================
8. Removed Extensions and SAPIs
========================================
========================================
9. Other Changes to Extensions
========================================
Curl:
. libcurl >= 7.15.5 is now required.
DBA:
. As of PHP 7.3.14, dba_open() accepts a fifth optional parameter for lmdb
databases which allows to specify the mapsize. The parameter defaults to
zero, in which case the compiled in default mapsize (usually 1048576) will
be used. The mapsize should be a multiple of the page size of the OS.
Filter:
. 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.
FTP:
. Set default transfer mode to binary
Intl:
. 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
MBString:
. The configuration option --with-libmbfl is no longer available.
ODBC:
. Support for ODBCRouter has been removed.
. Support for Birdstep has been removed.
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.
See <https://github.com/php/php-src/pull/3317>.
PCRE:
. 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.
See <https://wiki.php.net/rfc/pcre2-migration> for details.
PDO_DBLIB:
. Added the attribute PDO::DBLIB_ATTR_SKIP_EMPTY_ROWSETS to enable automatic
skipping of empty rowsets.
. Exposed the TDS version via the PDO::DBLIB_ATTR_TDS_VERSION attribute.
. DATETIME2 columns are now treated like DATETIME columns.
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.
Standard:
. var_export() now exports stdClass objects as an array casted to an object
(`(object) array( ... )`), rather than using the nonexistent method
stdClass::__setState().
Tidy:
. Building against tidyp (<https://github.com/petdance/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:
. 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:
. Added the zlib/level context option for the compress.zlib wrapper to
facilitate setting the desired compression level.

========================================
11. Changes to INI File Handling
========================================
- birdstep.max_links
. This INI directive has been removed.
- opcache.inherited_hack
. This INI directive has been removed. The value has already been ignored
since PHP 5.3.0.
- session.cookie_samesite
. New INI option to allow to set the SameSite directive for cookies. Defaults
to "" (empty string), so no SameSite directive is set. Can be set to "Lax"
or "Strict", which sets the respective SameSite directive.
- syslog.facility
- New INI to set syslog facility which specifies what type of program is
logging the message. It is used only when error_log is set to syslog.
- syslog.filter
. New INI to set syslog filter type to filter the logged messages. There are
3 supported filter types - all, no-ctrl and ascii. It is used only when
error_log is set to syslog.
- syslog.ident
. New INI to set syslog ident string which is prepended to every message. It
is used only when error_log is set syslog.
- mbstring.regex_stack_limit
. New INI directive (since 7.3.5) limiting stack depth of mbstring/oniguruma
regular expressions.
========================================
12. Windows Support
========================================
